J. CORRESPONDENCE CSAC 63.1.79/J.1 - J.158
K. Conspectus of Publications
The collection is extensive, relating to almost every aspect of Blackett's long and varied career in science and in public life. Blackett himself frequently used the material for lectures and writings on matters of particular personal or historical interest such as his period of research at the Cavendish Laboratory, Cambridge, under Rutherford, operational research and other controversies in the second world war, aspects of India's development, and the like. Furthermore, it is apparent that, towards the end of his life, he was assembling material for one or perhaps two books: a collection of writings and an autobiography. The clearest statement of his intentions is in a letter to M.M. Gowing dated 22 May 1972, in which he says: '... I am considering the possibility of publishing a volume of my collective papers, essays, lectures, etc.' (see CSAC 63.1.79/D.183); in November 1973 he writes in similar vein to the Director, National Maritime Museum: 'I am writing up a good deal about my activities during the war ...' (see CSAC 63.1.79/D.58); the note in H.123 would also seem to be part of a draft introduction to such a work. With this in view, Blackett obtained published or typed copies of the writings chosen for inclusion, revised and emended them, and sometimes added new linking material. Documents of this kind can be found in
CSAC 63.1.79/D.58, D.110, D.183 (quoted in part above)
CSAC 63.1.79/G.23-G.31, G.72, G.84
CSAC 63.1.79/H.1, H.64, H.77, H.96, H.109, H.110, H.119, H.124.
It will be seen that none of these refers to any of Blackett's 'scientific' work in the narrow sense.
As a result of these activities, and of the multiple provenance, the collection when received was in doubtful order. Although most of the folders bore Blackett's own note of the contents, this was not always a reliable guide, as he often 'cannibalised' previous work when preparing a lecture or paper, removing earlier work to a new folder or adding later material to the originals. While every attempt has been made to retain Blackett's preferred order in so far as it can be discerned, his headings and descriptions being preserved and indicated by inverted commas in the catalogue entries, some re-organisation was undertaken to bring the material under the broad headings of the List of Contents.
The introductory notes to the Sections and sub-sections of the catalogue indicate the main areas of interest in the collection.
Various episodes in Blackett's career can be clarified, or more accurately dated, from the manuscripts, and are briefly noted here in chronological order. Fuller accounts appear in the catalogue entries.
CSAC 63.1.79/J.35, correspondence with A.V. Hill on the date of Blackett's appointment as Scientific Adviser to General Sir Frederick Pile, A.A. Command;
CSAC 63.1.79/D.84, Blackett's paper, 'Scientists at the operational level', leading to his appointments as Chief Adviser Operational Research, later Director, Naval Operational Research;
CSAC 63.1.79/D.174, J.3, correspondence with C.R. Attlee and others on Blackett's paper on the international control of atomic energy;
CSAC 63.1.79/B.48, correspondence with C.D. Anderson on the discovery and naming of V-particles;
CSAC 63.1.79/E.24, E.33, papers and correspondence on the 'Gaitskell Group' of Labour Party advisers.
There are also the text of, or material relating to a substantial number of publications by Blackett omitted from the Bibliography accompanying the Memoir by A.C.B. Lovell (Biographical Memoirs of the Fellows of the Royal Society, 21, 1975, 1-115, also available as a separate publication). They are listed here in catalogue sequence.

CSAC 63.1.79/J.6, J.116
There are in addition many unpublished writings throughout the collection.
For all the wealth of material in certain areas, there are lacunae elsewhere. No documents survive, for example, relative to Blackett's long service with the National Research and Development Corporation 1949-64, or the Department of Scientific and Industrial Research 1955-60; and, of his correspondence in the war years, only that for 1942 survives (CSAC 63.1.79/D.126 - D.147).
Blackett always had a fondness for acronyms and abbreviations, and this grew stronger with age; same of his later notes and drafts bristle with clusters of initials which, in conjunction with his increasingly cramped hand and his habit of paginating by beginning with Roman I (on a page often later removed) and continuing in Arabic numbers 2...n, make them difficult to follow or attribute with confidence. Conversely, one can only admire his determination to maintain a presence in the world of scientific research despite great pressures of public life, and, later, of failing powers; the documents and correspondence on his last research (CSAC 63.1.79/C.182 - C.185) convey this especially clearly.
The material in Sections A - H is presented chronologically within the sub-sections designated in the list of contents. Section J. Correspondence, is in alphabetical order. Many of the Sections and sub-sections include a brief introductory note summarising their contents and drawing attention to material of particular interest.
Scientific research notes and data
Blackett's scientific fame rests in part on the versatility of mind which enabled him to make significant contributions to knowledge in several areas of research (particle disintegration, magnetic spin, rock magnetism) as well as to develop the technique of operational research. Nevertheless, these contributions emerged from a gradual evolution in Blackett's thinking, and there is no sharp switch from one to another even when there is a discontinuity in time (such as the long period of war service) or place (such as the various moves from Cambridge to Birkbeck, Manchester and Imperial College). The distinction between Sections B and C is therefore to some extent an artificial one, and cases of overlapping material are noted in the entries.
Almost all the material was received in Blackett's own folders, usually with his note of the contents in some abbreviated form, E.g., 'C.R.' (= Cosmic Rays), 'R.M.' (= Rock Magnetism). The contents of the folders may be any or all of the following: laboratory experiments, datasheets, graphs and calculations; notes, drafts and comments for talks or publications; Blackett's or others' offprints, sometimes annotated; correspondence. Bulky folders have been split into more manageable units, but kept together with a note of their original grouping. Blackett's titles and descriptions of the folders are given in inverted commas.
Blackett kept various sequences of his notes clipped or pinned together. These sequences have been retained in his order, although the pagination, size of paper, etc. are often heterogeneous.
Many of Blackett's own notes were made on the backs of previous notes, drafts, proofs, etc. No attempt has been made to give an account of such material.
Lectures and publications
Manuscript notes, typed drafts or offprints of Blackett's extensive output of lectures and writings are to be found throughout the collection. Those on specific research topics were kept by him with the data in Sections B and C and have been left there; similarly with material on operational research in Section D and on India in Section G. Section F groups together talks on three topics arising from Blackett's involvement in public life, and Section H contains the sequence of all other surviving documents of this type, including his Anniversary Addresses as President of the Royal Society and his speeches in the House of Lords.
Correspondence dealing with a specific research topic, lecture or publication was usually kept by Blackett in the same folder as his notes and drafts on the subject. Such material has been left in place whenever possible, or, if it has been re-allocated, a note has been made to that effect. The correspondence on magnetic spin (CSAC 63.1.79/C.41 - C.71) and on rock magnetism (CSAC 63.1.79/C.221 - C.268) is in chronological order and enables Blackett's thinking, his methods, and the graph of his activity to be clearly seen. The surviving correspondence on cosmic rays (CSAC 63.1.79/B.132 - B.147) is, though interesting, regrettably much less complete. There is very little material remaining from the war years.
Correspondence on overseas activities (CSAC 63.1.79/G.32 - G.51, G.82 - G.84) and general correspondence in Section J are in alphabetical order, with dates and an indication of any material of personal or scientific interest; a note is also made of cases when only Blackett's carbon copy survives.
Material in every Section is linked as far as possible to A.C.B. Lovell, Biographical Memoirs of Fellows of the Royal Society, 21, 1975, 1-115
References to the text are in the form Lovell, Memoir, p ...
References to the Bibliography are in the form RS ...
When this catalogue was in proof, Lady Blackett contributed some additional material, including plans and extracts from her husband's autobiography. These documents appear as CSAC 63.1.79/A.10A.
A biographical 'Memoir' of Sir Patrick Maynard Stuart FRS was written by Lovell and published in the 'Biographical Memoirs of Fellows of the Royal Society' Volume 21 1975 by the Royal Society.
The following is a conspectus of Blackett's publications as listed in the Bibliography of the 'Memoir', and the principal items in the catalogue to which they refer. Only the more extended references (to research, publication or reception of work and ensuing correspondence) are given, minor allusions in letters, requests for reprints etc being omitted.
This is followed by a copy of the Bibliography taken from the 'Memoir'. It is reproduced here by permission in order to enable users of the Conspectus to identify the full titles of works elsewhere referred to in the form RS....


The material in this Section covers every aspect of Blackett's long and varied career: his scientific achievements, his academic posts in Manchester and London, his wartime and political activities, and the many honours and awards he received.
Some of the material is in the form of photocopies of original documents still in family hands.
A substantial proportion of the Section (CSAC 63.1.79/A.45 - A.83) consists of letters, cables and messuages of congratulation received by Blackett on the award of the Nobel Prize (1948), the Copley Medal (1956), the Companionship of Honour (1965), his election as President of the Royal Society (1965), the award of the Order of Merit (1967) and his elevation to the peerage (1969). Many of these letters contain material of considerable biographical interest; they are not individually itemised in the list below, but are presented in alphabetical order, and indexed.

Letters, cables and telegrams of congratulation  CSAC 63.1.79/A.45-A.83  1948-1969

Received by Blackett on the award of the Nobel Prize (1948), Copley Medal (1956), Companionship of Honour (1965), Order of Merit (1967), his election as President of the Royal Society (1965) and his elevation to the peerage (1969).
Many of the letters are of interest for their biographical or historical reminiscences, discussions of scientific work, references to political activities or to social causes.
The letters on the Nobel Prize were kept by Blackett in an alphabetically indexed box file. These have been removed to folders but retain Blackett's original ordering.
The letters on the Companionship of Honor, the Presidency of the Royal Society and the Order of Merit were kept in three large bulky files. Each file has been split into nine smaller, alphabetically-arranged folders for ease of reference. Letters of congratulation on behalf of corporate bodies are generally filed under the name of the organisation.
If Blackett sent a typescript acknowledgement, the carbon is attached to the letter. Most of the correspondence generated by the award of the Nobel Prize was answered in this manner, but letters re the later awards were answered by hand.

One box of press-cuttings relating to Blackett and his activities, or to topics which were of interest to him.  CSAC 63.1.79/A.106  n.d


The material in this Section documents the first steps in Blackett's scientific career - his work at the Cavendish Laboratory under Rutherford, his year in Göttingen with Franck, his move to Birkbeck College, London, in 1933 to head his own department, and then to Manchester to occupy the Langworthy Chair of Physics. He photographed the disintegration of the hydrogen nucleus (1924), collaborated with Occhialini to provide evidence for the existence of the positive electron (1933) and supported the research of Rochester and Butler which led to the discovery of the V-particles (1947). Not all of the evidence has survived - whether in the form of laboratory notebooks, working papers or correspondence - but those documents which remain testify to Blackett's energy, persistence and deft experimental technique.
Section A should be consulted for several items of interest pertaining to Blackett's work on particle disintegration and cosmic rays - see especially his application to the Royal Society for a Moseley Fellowship (CSAC 63/1/79/A.12), press-cuttings relating to the electro-magnet built by Metropolitan-Vickers for Blackett and installed in the Magnet Hut at Birkbeck (CSAC 63/1/79/A.15), letters of congratulation on the award of the Nobel Prize, many of which recall Blackett's work which led to the award, and of course the obituary notices and tributes published after his death.
The material is presented as follows:
CSAC 63.1.79/B.1 - B.21 Laboratory notebooks on particle disintegration, 1920-32
CSAC 63.1.79/B.22 - B.61 Working notes and papers on particle disintegration and cosmic rays, 1923-56
CSAC 63.1.79/B.62 - B.67 Photographs of particle disintegration and cosmic rays
CSAC 63.1.79/B.68 - B.74 Working notes on theories of the origin of cosmic rays, 1949-55
CSAC 63.1.79/B.75 - B.83 Working notes on astrophysics, 1953-59
CSAC 63.1.79/B.84 - B.131 Lectures, broadcasts, publications, 1932-60
CSAC 63.1.79/B.132 - B.147 Correspondence, 1923-74
Because Blackett's research evolved from one topic to another, interest in each being aroused and developed by previous work, the above categories are not rigidly defined and are intended to provide only a rough guide to contents. Even if it were possible to distinguish areas of interest more strictly, Blackett's record-keeping would make inevitable some degree of overlap, since he often intermingled various types of document to suit his purposes, E.g. pages were torn from laboratory notebooks and kept with the working papers, photographs and notes for lectures were inserted in notebooks, etc. Wherever possible, the presence of 'anomalous' material of this kind is indicated in the entries below.

LABORATORY NOTEBOOKS  CSAC 63.1.79/B.1-B.21  1920-32

The notebooks are presented in chronological order as far as possible. They are all in Blackett's hand, unless otherwise indicated; other hands are identified where known.
The notebooks provide a record of Blackett's first research at the Cavendish Laboratory under Rutherford (CSAC 63.1.79/B.2 - B.4), his year at Göttingen with Franck (CSAC 63.1.79/B.10 - B.12) and his collaborative work with research students E.P. Hudson (B.13), F.C. Champion (CSAC 63.1.79/B.17 - B.18) and D.S. Lees (CSAC 63.1.79/B.15, CSAC 63.1.79/B.19 - B.20) in Cambridge.
Several incomplete sequences (CSAC 63.1.79/B.5 - B.6, CSAC 63.1.79/B.17 - B.18) indicate that some notebooks have not survived. Sometimes pages have been torn from the notebooks and kept with the working notes.

Blackett's folders of working notes and papers are of a very miscellaneous composition. An attempt has been made in the list below to present them in chronological order, but since many of the folders contain a wide range of material of differing dates, this ordering is of necessity somewhat artificial and incomplete.
Some originally very bulky folders have been split into several smaller folders for ease of reference, E.g. CSAC 63.1.79/B.22 - B.25, CSAC 63.1.79/B.35 - B.37; in some cases, manuscripts and drafts for lectures have been removed and listed sepaarately (see the introductory note to CSAC 63.1.79/B.84 - B.131).
Some of the papers refer to measurements and observations recorded in laboratory notebooks. It has not been practicable to cross-reference such cases to the notebooks listed above (CSAC 63.1.79/B.1 - B.21), since many of Blackett's notes refer to books which are missing from the sequence.
Some of the notes are written on the verso of examination scripts, others are on specially devised forms for the recording of data. All notes are manuscript, and in Blackett's hand unless otherwise indicated; other hands are identified where known.
All correspondence found with these working notes has been left in the folders, itemised and indexed (see the introductory note to CSAC 63.1.79/B.132 - B.147).

In 1946-47 G.D. Rochester and C. Butler, working with Blackett in Manchester, obtained the first photographs of V-particles. Their results were published in Nature, 160, 855. In 1949 the cloud chamber and magnet which Rochester and Butler had used to obtain their photographs was moved from Manchester to the Observatory on the Pic du Midi in the hope of photographing new tracks (see letters to Carl Anderson, 5 December 1949 and 26 April 1950, in CSAC 63.1.79/B.48).
CSAC 63.1.79/B.42-B.46 contain the initial correspondence: between Blackett and J. Rösch of the Observatory (with the intermediary help of G.

Cowan should spend some time in Blackett's laboratory at Manchester (he was unable to do so), and re verification by Anderson's team of Rochester's and Butler's hypothesis that forked tracks were 'caused by new unstable particles'; re Pic du Midi project and re naming of the new particles.
In his letter of 12 July 1950, Blackett suggests the names 'V-tracks' and 'V-particles' and adds: 'I would like to get our ideas set on this question before the end of August as I will be talking at the British Association on these particles on the 31st, and would like by then to have come to some decision as to what they should be called. I propose to write to Niels Bohr to ask for his approval when I have heard from you'. (see also Blackett's letter of 19 July 1950 to A.H. Chapman in CSAC 63.1.79/B.44);

Blackett kept his notes and drafts either among his working papers or in bulky folders labelled simply 'Cosmic ray lectures', each folder containing perhaps a dozen different lectures. These scattered manuscripts have been brought together and listed below in one chronological sequence. Those lectures which have been extracted from the working papers are cross-referenced to the folder in which they were originally found (i.e. CSAC 63.1.79/B.70 and CSAC 63.1.79/B.107).
Many of the notes for lectures are very brief jottings, occupying only one or two pages. Places and precise dates of delivery are given in the handlist where possible. Many of the later lectures are in the form of reminiscences of early cosmic ray research and thus provide interesting historical and biographical information. Other semi-autobiographical lectures which touch upon Blackett's work on particle disintegration or cosmic rays may be found in Section H. See also under Rutherford in the general index.
Occasionally, a lecture was directly related to the working notes with which it was found. These were left in situ and are briefly noted here for ease of reference: Copenhagen, 1931 (CSAC 63.1.79/B.29); Gassiot Conference, 1948 (CSAC 63.1.79/B.58); Florence, 1948 (CSAC 63.1.79/B.35); Paris, 1950 (CSAC 63.1.79/B.48); Oxford, 1950 (CSAC 63.1.79/B.49) and Bombay, 1950 (CSAC 63.1.79/B.49).
Published lectures are cross-referenced to the bibliography in the Royal Society Memoir, with the notation R.S.x, 'x' being the number in the bibliography. Some of the publications listed below do not appear in the Royal Society bibliography. See especially CSAC 63.1.79/B.115, CSAC 63.1.79/B.116, CSAC 63.1.79/B.120.

CORRESPONDENCE  CSAC 63.1.79/B.132-B.147  1923-1974

Related information: See also correspondence with H. Bhabha, D.S. Kothari, A.W. Mailvaganam in Section G., and letters of congratulation on the award of the Nobel Prize in Section A.

Very little remains of what must once have been an extensive correspondence on particle disintegration and cosmic rays. The little that is left, and which is presented below, has been extracted from miscellaneous folders found elsewhere in the collection; it is presented in chronological order, with an indication of contents.
Correspondence found with the working papers and notes in Section B has been left in situ and itemised in the entries for the relevant folders. The majority of the letters thus preserved are usually isolated items, or an exchange of letters over a brief period, which have survived largely by chance. Attention is drawn, however, to the following more extended sequences, of some historical interest: CSAC 63.1.79/B.42 - CSAC 63.1.79/B.46, extensive correspondence on the electro-magnet and cloud chamber erected on the Pic du Midi in 1948-49 and the observations recorded there; CSAC 63.1.79/B.48, an important and interesting exchange of letters between Blackett and C.D. Anderson of the California Institute of Technology in 1949-50 re the newly-discovered and as yet un-named V-particles, and their nomenclature.
Some of the correspondence in Section J. marginally refers to work on particle disintegration and cosmic rays. See the birthday message to Blackett from B. Rossi (CSAC 63/1/79/J.76) recalling their early collaboration, the letter from M. Cosyns (CSAC 63/1/79/J.20) hoping to rejoin Blackett in Manchester after the Second World War, and a letter from E.J. Williams, 1931 (CSAC 63/1/79/J.108).

Publications  CSAC 63.1.79/B.136-B.138  1937

In April 1937 Blackett communicated for publication in Proc. Roy. Soc. A. an experimental paper by himself and J.G. Wilson on 'The energy loss of cosmic ray particles in metal plates' (R.S.40). He then wrote a theoretical paper which he circulated in draft form to Rutherford, Dirac and Peierls for comment. (Blackett may have distributed it more widely but this is not apparent from the surviving correspondence.)
In his letter to Rutherford of 26 May 1937, Blackett wrote: 'I am awaiting your comments on my paper with great hope that you will think there is something in it! Heisenberg has written expressing great interest in our experimental paper, and saying that the results are extremely important for the further development of the theory. As our experimental paper is out, I think I had better publish the theoretical paper quickly - if it is considered not too unreasonable. For others will surely be getting on to the same points'.
In the event, Blackett did not publish this theoretical paper, but did communicate another paper in December 1937 (R.S.42) which accepted the conclusions of Neddermeyer and Anderson that two types of particles existed.
See Lovell, Memoir, pp.26-29 for full discussion of the Bhabha-Heitler theory and Blackett's response to it.

Rutherford then passed the paper on to E.V. Appleton for comment (see CSAC 63.1.79/B.137).

SECTION C MAGNETISM  CSAC 63.1.79/C.1 - C.289  [n.d.]

The generic term 'Magnetism' is used for convenience, to describe several related areas of scientific research and activity. These are:
CSAC 63.1.79/B.1 - C.71 Magnetic Spin and Rotating Bodies
CSAC 63.1.79/B.72 - C.268 Rock Magnetism, Continental Drift, Magnetic Field Reversal
CSAC 63.1.79/B.269 - C.285 Plasmas, Fusion Reactions
Each of these sub-sections, which may include research notes and data, lectures and writings, and correspondence, is preceded by an introductory note on the material and its presentation.


Blackett's principal period of research on this topic was 1946 - 51. His work on cosmic rays and their origin had led to an interest in astrophysics and the possible influence of magnetic fields on phenomena in electron showers. Further investigation led Blackett to postulate a proportional relationship between magnetic moment and angular momentum, which might constitute 'a possible general law of Nature for all massive rotating bodies'. This hypothesis, formulated in his 1947 paper published in Nature (R.S.56) attracted very wide attention among the general public as well as in scientific circles. (See CSAC 63.1.79/C.68 - C.71.)
Experiments to verify the hypothesis were devised and undertaken, Blackett's own chief contribution being the construction of a highly sensitive magnetometer which eventually gave a negative result and thus disproved the general validity of the earlier theory (R.S.64). (See CSAC 63.1.79/C.9 - C.12 and note.) The sensitivity of the apparatus, however, enabled weak magnetic fields to be detected, and was thus admirably suited to the work on palaeomagnetism to which Blackett turned his attention. (See CSAC 63.1.79/C.72 - C.268 and the introductory note.) Blackett's letters to J.W. Warwick, M. Farbstein (C.64) and W. Sullivan (J.97) give his account of his hypothesis and its history.
See Lovell, Memoir, pp.39-44, and R.S.54, 56, 60, 61, 62, 64.
The material is presented as follows:

Drawings, calculations and correspondence relating to the design of a magnetometer to measure the magnetic fields of a rotating sphere (see Lovell, Memoir, pp.41-43).
This magnetometer was designed to test the hypothesis advanced in Blackett's 1947 paper (RS.56) of a relation between the magnetic moment and the angular momentum of massive rotating bodies. He began to plan its design immediately after the publication of his paper, and observations are recorded from 9 August 1947 (see CSAC 63.1.79/C.30-C.32 for laboratory notebooks of observations on the apparatus). The sensitivity of the instrument enabled earlier experiments, by Swann and Longacre, Schuster and Wilson, and others, to be further tested, a negative result being obtained and presented in Blackett's 1952 paper (RS.64).
This magnetometer thus disproved Blackett's own 1947 hypothesis, which had attracted great attention at the time, but its superior sensitivity made possible further advances in paleo-magnetism.

LABORATORY NOTEBOOKS  CSAC 63.1.79/C.30-C.40  1947-54

The ten surviving notebooks form part of three different incomplete sequences as follows:
CSAC 63/1/79/C.30-C.32, at Manchester University, almost entirely in Blackett's hand. It should be noted that the First observations recorded (in CSAC 63.1.79/C.30) are dated '9.8.47.', and that observations headed 'Jodrell' are dated '16.1.49.' (p.25 of CSAC 63.1.79/C.30).
Lovell, Memoir, gives 'during the spring and summer of 1949' as the beginning of measurements at Jodrell Bank.
CSAC 63/1/79/C.33-C.38, at Jodrell Bank. The majority of the observations are by J.M. Pickering, checked and annotated by Blackett. Some are entirely in his own hand.
CSAC 63/1/79/C.39-C.40, at Imperial College, London, where the work was continued after Blackett's appointment to the Chair of Physics in succession to G.P. Thomson. These books are entirely in Blackett's own hand.

Three laboratory notebooks, nos. 1, 5, 8 of an incomplete sequence  CSAC 63.1.79/C.30-C.32  1948-1950

Red notebook, cover labelled Book 1 1948-49  CSAC 63.1.79/C.30  1949

(Observations begin 9.8.47. inside book) to 18.7.49.
Observations dated 16.1.49. (p.25 in book) are marked 'Jodrell'.

Green notebook, cover labelled 'Book 5'  CSAC 63.1.79/C.31  1950

Observations 30.1.50. to March 1950.

Black notebook, cover labelled 'Book 8.  CSAC 63.1.79/C.32  1950

All books contain notes and calculations on the working of the magnetometer installed at Manchester University, and experiments carried out with it. Almost all the work is in Blackett's hand, sometimes with later corrections or re-thinking in pencil or red ink. Sometimes a page is in another hand, later checked over by Blackett.

Six laboratory notebooks, nos. 4, 5, 6, 7, 8, 9 of an incomplete sequence, all labelled 'Jodrell', containing observations of magnetic swing under various conditions.  CSAC 63.1.79/C.33-C.38  1950-1951

The observations cover the following periods

Observations Book 4  CSAC 63.1.79/C.33  July-October 1950

Observations Book 5  CSAC 63.1.79/C.34  October-November 1950

Observations Book 6  CSAC 63.1.79/C.35  October 1950-February 1951

Observations Book 9  CSAC 63.1.79/C.38  January-April 1951

All these books are labelled inside 'J.M. Pickering, Manchester University' and contain her observations, checked and annotated by Blackett, as well as Blackett's own.

Two black notebooks, nos. 2 and 3 of an incomplete sequence, labelled 'ROTOR 2. October 1953 to January 1954' and 'ROTOR 3. January-April 1954', with Blackett's name inside, and pages numbered by him.  CSAC 63.1.79/C.39, C.40  1953-1954

Continuation, at Imperial College, London, of work begun at Manchester: notes and dates of experiments carried out, or ideas for further experiments, calculations and queries. These books are entirely in Blackett's hand.


The topics principally referred to are:
Blackett's hypothesis, as set out in his papers of 1947 and 1949 and in related talks, its reception and discussion.
Experiments arising from the hypothesis, especially the new magnetometer and the 'White Dwarfs' experiment (CSAC 63.1.79/C.42-C.44, see also CSAC 63.1.79/C.13), and other possible experiments.
Later observations on geomagnetism.

Correspondence on 'White Dwarfs'  CSAC 63.1.79/C.42-C.44  May 1947-January 1948

Following his 1947 paper, Blackett attempted to interest astronomers in examining the spectra of white dwarfs for evidence of polarisation. It was hoped to undertake the experiment at the Solar Physics Laboratory, Cambridge, under the direction of A.D. Thackeray; it proved unsuccessful with the available equipment and conditions.

This work, begun at Manchester, was continued at Imperial College, London, where it became Blackett's chief research interest. There is some overlap between the later work at Manchester (see CSAC 63/1/79/C.39 - CSAC 63/1/79/C.40 above) and its continuation at Imperial College, where some of Blackett's research students and collaborators followed him (see especially the letter from J.A. Clegg, December 1952, in CSAC 63/1/79/C.221).
Blackett made contributions to the study of continental drift and of magnetic field reversal, through his own researches, lectures and publications, through his initiation and encouragement of research teams in UK and abroad, and by the devising of improved instruments and techniques of magnetic measurement. All these activities can be amply documented from the records below, though Blackett's contribution to the debate on continental drift is more widely known through lectures and writings, while his work on field reversal is more extensively displayed in the data and working notes than in published work.
The high proportion of notes in his own hand in the folders below indicates his urge to maintain personal involvement in scientific research during a period when much of his time was occupied with heavy public and political commitments in Britain and overseas (see Sections E and G), and his Presidency of the Royal Society. His interest in rock magnetism continued to the end of his life; see especially CSAC 63/1/79/C.125 - CSAC 63/1/79/C.188 for the extensive data on magnetic field reversal and drafts for unpublished papers on the subject, and the correspondence with R.L. Wilson (CSAC 63/1/79/C.182) and C.W.F. Everitt (CSAC 63/1/79/C.268).
Attention is drawn to CSAC 63/1/79/C.72 (1954) and CSAC 63/1/79/C.125 (1967), which contain particularly clear expositions of Blackett's thought on the subject at the dates in question and, with more specific reference to magnetic field reversal, to CSAC 63/1/79/C.170 - CSAC 63/1/79/C.171.
The material is presented as follows:
CSAC 63/1/79/C.72-C.188 Working notes and data 1953-73
These folders, while generally following chronological order, often group themselves about a specific paper or papers in which Blackett summed up his research to date and advanced hypotheses: for example, CSAC 63/1/79/C.106 - CSAC 63/1/79/C.124 and introductory note, dealing with his paper on climatology (R.S.88), and CSAC 63/1/79/C.125 - CSAC 63/1/79/C.188 and introductory note, dealing with his unpublished work on magnetic field reversal.
Correspondence found in these folders has been left in place, as have drafts or notes for lectures. The correspondence, when seen in chronological order with its related notes and data, gives a good picture of Blackett's drive in pressing on a research project.

Letter to Sir Ben Lockspeiser  CSAC 63.1.79/C.70,C.71/C.72  1954

To accompany Blackett's application to Department of Scientific and Industrial Research for three substantial research grants 'to support the study of rock magnetism' by himself and S.K. Runcorn. 5 pp. duplicated typescript. 3 May 1954
In this letter, Blackett says:
'As the subject and possibilities of rock magnetism are not very well known in this country, I have thought it fit to attempt to give a short outline of its history, and of possibilities which may result from further work.'
The succeeding 'Notes' review current work throughout the world, the contribution of various researchers (many of whom supplied specimens, data or other information to Blackett, and corresponded with him), existing hypotheses especially on field reversal, Blackett's attempts to initiate co-operative projects on an international level (especially in South Africa and with Bhabha's Institute at Bombay), the importance of the project, and Blackett's belief that at that time 'this country has, largely through the operation of various accidental causes, taken over the lead in the application of rock magnetism to geophysical problems'.

This paper was referred to as 'Climatology Paper' in many of the documents, and used by Blackett as a running title on his folders.
These folders, though incomplete and disordered, well illustrate Blackett's method of work. In addition to the large proportion of graphs, notes and calculations in his own hand, the correspondence shows his continuous search for information and new data from colleagues, and his incorporation of the latest findings into successive drafts and revisions of his paper.
Correspondence on special topics, E.g., corals, remains in the relevant folders among the working papers, where Blackett retained it; other correspondence is in his 'Correspondence' folders, CSAC 63.1.79/C.114 - C.123.

WORK ON MAGNETIC FIELD REVERSAL  CSAC 63.1.79/C.125-C.188  1961-1967

This topic occupied much of Blackett's interest in rock magnetism; he delivered a paper on the subject at the International Conference at Kyoto, Japan, in 1961 and from about 1964 concentrated almost entirely upon it, with the help of his research assistants, notably Miss J.L. Langbein. The working papers are very extensive both in time and in the detail of the recordings, measurements, calculations and drafts.
The unpublished paper 'Some observations of the petrology of normal and reverse lavas', subtitled 'Progress Report on Work carried out since 1965' and dated July 1967, provides a brief account of the work and a guide to the detailed worksheets. It has therefore been taken out of chronological sequence and placed at the head of this section as item CSAC 63.1.79/C.125, together with 'Table 1. Details of sites and samples' (included as a loose page) which lists the sites and the names of the collectors of samples. The working papers are presented in the order of the sites (15 in all) and many of the folders include correspondence with the collectors.
Although the 1967 paper refers to 'work carried out since 1965', some of the work began earlier (several folders and letters are dated from 1963) and Blackett maintained his interest and research on the problem after 1967. Items CSAC 63.1.79/C.162 - C.188 deal with the continuation of the analysis, and also with additional samples analysed and measured in the period 1965-67 but not included in the 15 sites chosen for the 1967 paper.
Much of the work is in Blackett's hand and indicates his determination to give whatever time he could to scientific research despite his many political activities at this period (see Section E). The titles and descriptions in inverted commas are those he gave to folders, bundles of notes or data. Work in other hands has been identified wherever possible.
The material is presented as follows:
CSAC 63.1.79/B.125 - C.132 Texts, drafts and corrections of July 1967 paper.
CSAC 63.1.79/B.133 - C.161 Working papers on field reversal 1962-67, preceding July 1967 paper.
CSAC 63.1.79/B.162 - C.165 Working papers on field reversal not used in July 1967 paper.

Re-working of data, with special reference to the 'oxidation controversy'.  CSAC 63.1.79/C.170-C.188  1967-1968

Related information: See CSAC 63.1.79/C.219 for lectures by Blackett on oxidation.

These folders deal with new research, or the re-working of previous samples and data, in an attempt to determine whether field reversal was attributable to changes in the earth's magnetic field, or was self-induced by magnetic interactions between differing iron/titanium oxides (the Fe-Ti relation referred to in the correspondence and documents below).
The work was mainly based on samples provided by J.M. Ade-Hall and R.L. Wilson at Liverpool University, with whom Blackett maintained regular links by correspondence and visits. See the relevant correspondence in CSAC 63.1.79/C.212-C.268 below.
Blackett's ideas on the subject can be seen developing in CSAC 63.1.79/C.170-C.171, and are set out humourously in CSAC 63.1.79/C.172.
With the exception of tables of results, etc. sent to Blackett for information, all these notes, worksheets and classification of data are in his own hand, which becomes increasingly cramped in the later work.

Some of the notes are in sequence, others are loose pages; most have no date, but some have dates 1966, with 1 p. 'Random Thoughts!' January 1968.
The file includes a 2 pp. sequence of assumptions and deductions on oxidation and self-reversal dated 15.5.66, and a draft for 'Appendix' probably for July 1967 paper.
The folder gives a good impression of Blackett's methods of work.

Notes  CSAC 63.1.79/C.172  n.d

2 pp. ms. notes, with many additions and revisions, of an examination of the field and self-reversal controversy expressed in parodic form as a legal case 'Core v/s Surface', described as 'Situation like last chapter but one of one of the detective stories by one of Oxford's Hon.D. Laws'. The pages are numbered 5 and 6 by Blackett and presumably formed part of a longer sequence which has not survived.
The notes include 'Case for prosecution of Earth's core' (i.e. self-reversal), 'The Core's Case for its Defence', and verdict of 'NOT PROVEN'.
There are also 2 quatrains of rhyming couplets by Bret Harte, copied out by Blackett.
There is no indication of place or date, or whether the 'case' was publicly delivered. The paper used is the same as for the 'Random thoughts' notes dated 1968 in CSAC 63.1.79/C.171.

Extensive correspondence with R.L. Wilson  CSAC 63.1.79/C.182  1971-1973

April 1971-July 1973. The correspondence shows Blackett's continuing wish to maintain an active interest in rock magnetism, and to participate in research. He undertook petrological analyses of Western Icelandic rock samples for Wilson, and exchanged results and information throughout 1972. Here, as in earlier work, Blackett insisted on some form of coding so that the work was done 'blind' to avoid any possibility of biased findings; tables and data to accompany specific letters have been left as received.
In his letters of May and July 1973, Blackett admits his inability to complete the task or undertake any further research, and concludes: 'I certainly won't undertake any more petrological work - in fact I won't do any more experimental work at all'.

Extensive worksheets, calculations, graphs, etc. on Western Icelandic rocks sent from Liverpool by R.L. Wilson, all in Blackett's hand, various dates January-September 1972.  CSAC 63.1.79/C.183  1972

Related information: Additional correspondence on rock magnetism appears in CSAC 63.1.79/C.81-C.82, C.98-C.100, C.105, C.114-C.123, and passim among the related working papers.

Blackett kept his correspondence on rock magnetism in roughly chronological order, in very bulky folders, separate from his other letters. The original bulky folders have been split into more manageable proportions, but the chronological order has been retained since it reveals the development of his ideas through his own and others' researches, and the urgency with which he pressed on a project which interested him. Sometimes Blackett would remove material of special interest or relevance and interfile it with the related datasheets or working papers; such letters have been left in place, and a note made on the relevant items in earlier entries. Blackett also kept in a special folder correspondence specifically related to his major paper on climatology (R.S.88): see CSAC 63.1.79/C.114-C.123.
In the folders below, extensive correspondence with an individual has been kept together, with terminal dates and some indication of content. (See especially the entries for J.M. Ade-Hall, E.C. Bullard, S.K. Runcorn, R.L. Wilson.) With these exceptions, the material is presented chronologically, thus enabling the development of Blackett's thinking, and the peaks of his activity in this field of research, to be followed.
The correspondence is particularly heavy for 1964-66, when Blackett was actively pursuing the research for the unpublished paper of 1967. During this period he was in constant touch with colleagues, requesting samples, discussing results, methods and equipment, preparing papers and the like; there is also a small amount of administrative correspondence about grants, degrees, appointments, etc. for his research students.
The ensuing decline of Blackett's active research is also reflected in the correspondence. His last letter to C.W.F. Everitt, February 1974, is very interesting in this respect (C.268).
A brief indication is given in the catalogue entries of any material of particular scientific or personal interest, and all correspondents are listed in the general index.

Correspondence with C.W. Francis Everitt.  CSAC 63.1.79/C.268  1974

In his reply, Blackett writes (February 1974): 'I am still interested in the origin of the Earth's magnetic field and I still have interest in diversed (sic) magnetisation but agree with the general view that these reversals are wholly dependent on the reversals of the Earth's core', and 'I am still just as puzzled as I was many years ago'.


Work on thermonuclear reactions at Imperial College was begun by G.P. (Sir George) Thomson in 1945-46. Its nature and development are clearly explained in a Note by Thomson contributed to the Minutes of the Governors' Meeting, 25 February 1958, which appears as CSAC 63.1.79/C.269 below. See also CSAC 63.1.79/D.200, Thomson's letter and note to Blackett of June 1946 in which he explains his early ideas for a torus.
Blackett's own interest in the use of a magnetic field in fusion reactions seems to date from 1958. As always, he pressed on the research, producing copious notes and narratives incorporating new material as it came to hand, testing and checking his own and others' calculations and using the results for lectures, discussions, etc. His lectures at the Tata Institute, Bombay, in February 1958 (C.271) represent his first presentation of the work of the Imperial College team, many of the notes and working papers being additions to and revisions of this.
The reports by R. Latham and J.A. Nation in CSAC 63.1.79/C.275 set out the conclusions of the work done in 1958-59.
None of the notes in this section go beyond 1959; though Blackett lectured as 'Controlled fusion reactions' in 1961 (R.S.85) there is no surviving material relating to that occasion.

This designation subsumes Blackett's activities on various defence projects and as a member of government committees before the outbreak of war in 1939, and his continuing service in similar capacities after its conclusion, as well as 'war work' in the stricter sense.
As has been pointed out (Lovell, Memoir, pp.50-69), Blackett conducted research for and contributed to the work of all three Services, in addition to his development of 'Operational Research' as a non-specific technique of investigation. The folders below attempt to present the material under headings related to committees, projects or areas of activity, within a roughly chronological order, though the rapidity of Blackett's movements sometimes makes this unattainable. 'Operational Research' has been treated as a separate section (CSAC 63.1.79/D.83 - D.125) because of its continuing value as an investigative method on which Blackett lectured and conducted correspondence for many years.
As with the working papers in Sections B and C, correspondence, lectures or talks which accompanied the research notes have been left in place.
It should be noted that the folders listed below describe only such documents as survive of Blackett's work during this period, and do not claim to be a complete record. Nothing remains, for example, of his wartime correspondence other than that for 1942 (CSAC 63.1.79/D.126 - D.147) and the letters interfiled with the working papers. Furthermore, because of the national importance of the work, and the public interest which was increasingly shown in it, Blackett re-worked the material on several occasions for writings or lectures, or in response to outside enquiries. The original order of the papers was therefore considerably disturbed and some material is likely to have been removed and not always returned.
The material is presented as follows, each sub-section being preceded by an introductory note:
CSAC 63.1.79/D.1 - D.10 Correspondence and papers 1936-40

THE MARK XIV BOMBSIGHT  CSAC 63.1.79/D.38-D.58  1940-45, 1973

This refers to the Mark XIV continuously set vector bombsight, sometimes referred to as the 'Blackett sight'. It was developed at R.A.E. Farnborough, from an idea of Blackett, during his connection with the Establishment for the work on fuzes, and subsequently further developed and tested there and at other Establishments. Folders CSAC 63.1.79/D.17, D.18 above contain the early drafts, working papers and graphs of test performances of the sight, which Blackett himself referred to as a 'stabilised sight' but which is called 'Blackett sight' on the R.A.E. documents in those folders.
Folders CSAC 63.1.79/D.38-D.50 below consist mainly of official reports and papers, typescript or stencilled, on the testing, development and use of the Mark XIV sight in British and US aircraft, and on German devices. The material is presented chronologically and is itemised in some detail in view of the statement by Lovell, Memoir, p.55, that 'the relevant R.A.E. files have been destroyed'.
Folders CSAC 63.1.79/D.51-D.57 contain miscellaneous committee papers and reports, many annotated by Blackett, on various aspects of bombing tactics and the U-boat campaign, as well as of bombsight design. They run from December 1939-February 1941.
Blackett himself clearly felt that the work had had some importance, since he wished to include some account of it in a proposed autobiography in 1973 (see CSAC 63.1.79/D.58).

In his letter of 1 November 1973 Blackett explains: 'I am writing up a good deal about my activities during the war, particularly certain parts of operational research and I felt I would like to mention the Mk 14 Bomb Sight as this was conceived and designed by a young colleague of mine at Birkbeck College and was a great success'. Later he says: 'I am only interested in what we did in 1943 ...' but this would appear to be a slip of the pen.

PAPERS ON BOMBING POLICY  CSAC 63.1.79/D.59-D.78  1941-46, 1962

These include the period of the confrontation on bombing policy involving Tizard, Blackett and Cherwell (see Lovell, Memoir, pp.64-65) and also material preceding and following it. Blackett worked over these papers on more than one occasion after the events; in particular he made considerable efforts in 1962 to locate certain missing reports (see CSAC 63.1.79/D.76-D.78 for correspondence on this subject), but it is clear that the remaining material is still incomplete.
See under Tizard in the Index of correspondents for other material on these matters.

OPERATIONAL RESEARCH (O.R.)  CSAC 63.1.79/D.83-D125  1940-74

Blackett became known as the 'virtual founder' of O.R. studies in Britain (though he makes clear in R.S.65 and elsewhere that this was not the literal truth) because of the great impetus given to the subject by the outbreak of war and the many new weapons, techniques and devices then rapidly being introduced. His early studies of radar for A.A. Command (D.83) led to the development of an O.R. unit for Coastal Command, and then to his appointment as C.A.O.R. and D.N.O.R. at the Admiralty, where he worked especially on convoys and the anti U-boat campaign (see CSAC 63.1.79/D.78-D.81 above, and D.84).
Blackett lectured extensively on the subject to Service personnel throughout the Second World War. After the War, he continued to lecture, though less frequently, and also wrote up some of his material for general publication. He returned to the subject on several occasions, notably in 1961 (see CSAC 63.1.79/D.109) and at the end of his life (see CSAC 63.1.79/D.110).
See also CSAC 63.1.79/J.54, J.60 for references to Blackett's service at the Admiralty on Operational Research.
The material is presented as follows:

3 pp. Typescript dated 10 November 1940 with ms. 'note' added, 20 December 1940, amending some of the information.
This is one of the reports on 'rounds per bird' prepared on the effectiveness of radar in London's air defence, during Blackett's service with A.A. Command as Scientific Adviser to General Sir Frederick Pile. See Lovell, Memoir, pp.56-58.

'Scientists at the Operational Level  CSAC 63.1.79/D.84  1941

Notes on Statement to Admiralty Panel on 16.9.41. on the function of an Operational Research Section (O.R.S.)'
These are based on the talk given to senior staff at the Admiralty, in which Blackett explains how 'the scientist can encourage numerical thinking on operational matters, and so can help to avoid running the war by gusts of emotion'.
The talk and document led to Blackett's appointment as Chief Adviser Operational Research with effect from 10 December 1941. See also CSAC 63.1.79/A.16.
When the document was published by Blackett in 1962 (R.S.91) (see CSAC 63.1.79/D.101, D.102) Blackett gave the date as December 1941. Lovell, Memoir, p.60, n, corrects this to 31 October 1941, but it will be seen that the date was in fact 16 September 1941.
Included here is a letter agreeing to allow Blackett 'the full services of Dr. Bullard as your Deputy'. The letter is dated 23 April 1942 and stipulates that Bullard should continue certain other work as 'we need somebody of Bullard's calibre to hold things together'.

Ms. draft, n.d., beginning: 'In a former paper I have attempted to outline some methods... for analysing the complex material provided by real operations of war'. The reference is presumed to be to CSAC 63.1.79/D.86 and the present paper on 'large changes' gives examples drawn from the U-Boat war and air attack to the end of 1943, and is therefore tentatively dated then.

The Committee was set up under the Chairmanship of Tizard to report on future technical developments in weapons of war. Atomic weapons were excluded from its terms of reference.
Members of the Committee were: J.D. Bernal, P.M.S. Blackett, C.D. Ellis and G.P. Thomson. The Committee reported in June 1945, and in October 1945 a revision was initiated by the Joint Technical Warfare Committee of the Chiefs of Staff Committee 'in the light of later knowledge about atomic energy' (see CSAC 63.1.79/D.161-D.183).
Items CSAC 63.1.79/D.149-D.157 below contain reports, discussion papers and ideas contributed by members of the Committee or by others on various specialised areas relevant to the Committee's work. Blackett retained and annotated copies of these papers, and also prepared his own notes for the Committee's report (D.158-D.160) in which he marshalled and presented some of the material.
The papers are preceded (D.148) by an undated draft by Blackett on a similar topic, probably written in 1942, in response to a Note from the First Sea Lord, Admiral Sir Dudley Pound. Blackett's draft, though incomplete, shows his interest in future weapons and the allocation of defence spending at a considerably earlier date than the setting-up of the Sub-committee.

2 pp. pencilled draft for the opening sections of a paper  CSAC 63.1.79/D.148  1942

'After the war, a decision will have to be taken by the Government as to the total fraction of the national resources which are to be allocated to the armed forces.'
The ms., which is undated and incomplete, accompanies extracts from a Note prepared for Chiefs of Staff Committee, 15 November 1942, by First Sea Lord. The note, initialled 'D.P.' (Sir Dudley Pound), refers to 'a number of scientific and technical matters of vast proportions and great complexity' and suggests:
'... the formation of an ad hoc scientific commission to obtain an objective scientific analysis of this policy and its affect (sic) on other operations. I suggest the commission should consist of Sir Henry Tizard, Professor Bernal, Dr. L.B.C. Cunningham, Sir Charles Darwin, Professor Blackett and that the Prime Minister should be asked to allow Lord Cherwell to preside over this body'.
Also included is an extract from Chief of Staffs Committee meeting 319, in which Pound put forward the suggestion and was answered by Portal that 'he did not think that an examination of the problem by a group of scientists would be of any advantage'. This document is dated 18 November 1943, but must refer to 1942. Pound died in October 1943.

Blackett's folder labelled 'Papers for Tizard Committee'  CSAC 63.1.79/D.149-D.157  1945

Containing reports and discussion papers sent to him by other members of the committee, or by outside sources, and containing material which he used in preparing his own 'Notes for Tizard Report' (D.158-D.160).
Note: These documents are all on poor quality wartime paper and are in fragile condition. Many still bear the security categories applicable at the time they were written, and Blackett's notes and underscorings.

Notes for Tizard Report'  CSAC 63.1.79/D.160  1945

2 pp. ms. notes for above, incorporating items from the material in CSAC 63.1.79/D.149-D.157 above, with a note of the relevant paper to be used or quoted.


This was a Sub-committee of the Chiefs of Staff Committee, instructed 'to proceed with the revision of Sir Henry Tizard's Ad Hoc Committee's report on the future development of weapons of war in the light of later knowledge about atomic energy which will be made available to them'.
The material consists mainly of Blackett's own notes, drafts and background research for papers or for discussion at meetings. It also includes similar documents sent to him by colleagues or interested parties. Some correspondence, with scientific, Service or government colleagues has been left in the folders, itemised and indexed.
The official invitation to serve on the Committee 'to consider this important topic' is dated 6 October 1945 (D.161), but Blackett had already assembled material and drafted short papers on various relevant aspects, and continued to do so. Items CSAC 63.1.79/D.162-D.166 are papers and notes of this kind on the implications of atomic warfare, brought together by Blackett August-September 1945 before the Committee was formally set up. Some of the later notes are headed 'TWC 46' and 'ACAE' (Advisory Committee on Atomic Energy, see CSAC 63.1.79/D.184-D.205) and represent Blackett's reflections prompted by papers or discussions at these committees.
Problems of atomic (later nuclear) weapons became the principal subject of concern, and on two occasions Blackett openly took a dissenting view from official decisions on the manufacture of an atomic bomb by Britain, and on international control of atomic weapons.
The minority papers which he wrote and circulated on both these occasions are documented in the folders below. The drafts and notes, and the correspondence which accompanies them, help to elucidate the dates of composition and circulation of the papers, and the comments they evoked at the time.
CSAC 63.1.79/D.167, D.168 refer to Blackett's memorandum of November 1945 'Atomic Energy. An Immediate Policy for Great Britain', which was reproduced in M.M. Gowing, Independence and Deterrence, London 1974, Vol.I, pp.194-206.
CSAC 63.1.79/D.174-D.181 refer to the paper on international control of atomic energy, which Blackett considered impractical and indeed undesirable in view of American superiority in atomic weaponry at the time. This paper was presented to the Prime Minister (Mr. Attlee) and was subsequently circulated as a 'Gen 75' Committee paper. In particular, the correspondence in CSAC 63.1.79/D.174 makes it clear that the paper was submitted to the Prime Minister in November 1946, three months before it appeared as a 'Gen 75' paper in February 1947 (see Gowing, op.cit., pp.115, 183).
See also CSAC 63.1.79/J.3, correspondence with CSAC 63.1.79/C.R. Attlee, and CSAC 63.1.79/D.201, Blackett's letter to Stafford Cripps, referring to another meeting he had had with the Prime Minister to discuss atomic energy policy in February 1947.

ADVISORY COMMITTEE ON ATOMIC ENERGY (ACAE)  CSAC 63.1.79/D.184-D.205  August 1945-April 1949

This was the 'Anderson Committee', set up in August 1945
'(a) To investigate the implications of the use of atomic energy and to advise the Government what steps should be taken for its development in this country for military or industrial purposes;
(b) To put forward proposals for the international treatment of this subject'
The folders also include material related to ACAE's Subcommittee on Nuclear Physics established in December 1945 'to make recommendations regarding research in nuclear physics in this country as a whole'.
ACAE was dissolved in January 1948, and the Subcommittee was reconstituted as the Nuclear Physics Committee responsible to the Ministry of Supply. Its Chairman was Sir James Chadwick; Blackett was Vice-Chairman.
See M. Gowing, Independence and Deterrence, 2 Vol., London 1974, passim.
The material consists of correspondence, reports, Blackett's notes of meetings, etc. Because they reflect various aspects of an important historical episode, they have been presented in some detail, and follow chronological order as far as possible.

POLITICAL ACTIVITIES  CSAC 63.1.79/E.1 - E.76  1939-1969

The papers in this Section fall into two groups.
There is a relatively small amount of material relating to the Association of Scientific Workers, with which Blackett had a long connection and of which he was President 1943-47.
The bulk of the material consists of papers relating to the work of discussion groups in the Labour Party which met under various names and sponsors with the aim of preparing a policy for science and technology to be implemented under a future Labour Government, and in particular to the development of the idea of a Ministry of Technology which was instituted after the Party's victory in the General Election of October 1964.
A considerable amount of duplicated or typescript reports, research and discussion papers and similar documents, circulated to Blackett by the Labour Party or other groups, or by individuals, remains in the folders. Blackett drew upon it as background material at various times for his own papers, and it is also a record of activity in one aspect of the preparation for the 1964 General Election and the formation of the Ministry of Technology.
Although all the material in this Section is concerned with political activity, it by no means represents the whole of Blackett's involvement in political matters as recorded in the collection. Reference should also be made to Section F, in particular to CSAC 63.1.79/F.26 - F.38 (The Trend Committee), and to lectures and writings in Sections G. and H.
The material is presented in the following sub-sections, though there is inevitably some degree of overlap. Each sub-section is preceded by an introductory note.
CSAC 63.1.79/E.1 - E.23 Association of Scientific Workers (A.Sc.W.) 1939-48, 1963-67
CSAC 63.1.79/E.24 - E.34 'The Gaitskell Group' 1956-63

CSAC 63.1.79/E.75, E.76 Press-cuttings and printed matter


Related information: See also CSAC 63.1.79/F.11.

Blackett became a Vice-President of the Association in 1939 and served as its President from 1943 to 1947. During his term as President, Blackett delivered numerous lectures relating to the work of the Association in which he stressed the need for scientists to play a larger role in post-war economic and political affairs. He also called for closer links between scientists and the organised trade union movement. To this end, he sponsored a resolution at the 1945 T.U.C. that a scientific advisory committee should be established; Blackett was one of the three A.Sc.W. representatives on the first committee, which was formed in 1946.
In addition to the lectures and publications, the papers also include 2 chronological sets of correspondence, 1939-48 and 1963-67, and one folder of printed matter re the Association.

THE 'GAITSKELL GROUP'  CSAC 63.1.79/E.24-E.34  1956-63

This was a group of senior scientists and politicians who met occasionally 'with the aim of evolving a scientific and technological policy for the country'. The meetings were organised and hosted by J.R.M. Brumwell, who also acted as secretary. When the group began meeting in July 1956, H. Gaitskell was the Leader of the Labour Party and attended the meetings. Later he was represented by H. Wilson. Even after Wilson succeeded Gaitskell as Leader, Blackett continued to refer to it as the 'Gaitskell Group', and this description has been used in the entries.
In 1959 a set of 'Cabinet Papers' was prepared for Gaitskell (see CSAC 63.1.79/E.27 and CSAC 63.1.79/E.28). Blackett often used or commented on these papers during the next several years - see especially CSAC 63.1.79/E.39 and CSAC 63.1.79/E.54. In July 1963 another set of 'Cabinet Papers' was prepared, this time for H. Wilson and R.H.S. Crossman. See CSAC 63.1.79/E.41, CSAC 63.1.79/E.44, CSAC 63.1.79/E.45, and CSAC 63.1.79/E.50 for copies of, or comments on these papers.
The composition of the group varied over the years but it included on occasion (in addition to H. Gaitskell and H. Wilson) J. Callaghan, A. Robens, R.H.S. Crossman, J.D. Bernal, J. Bronowski, G. Dickson, R.G. Forrester, D. Glass, B. Lockspeiser, P.M. Newitt, C.P. Snow, B.R. Williams, P. Shore and G. Mitchison. Blackett was a senior member of the group from its inception and one of its most senior scientists. The note sent along with the letter to Gaitskell in November 1962 (E.33) provides a useful summary of the group's activities. After Crossman became Shadow Minister for Education, he initiated more official conferences, several of which were held in the Bonnington Hotel, London. (See CSAC 63.1.79/E.42, E.56, F.33, F.34.)

The formation of the Ministry of Technology followed the victory of the Labour Party at the General Election of October 1964; the Minister was F. Cousins. Blackett became Deputy Chairman of the Advisory Council on Technology and Scientific Adviser to the Ministry. This gave him at the time 'immense power' (Lovell, Memoir, p.80), but he had also had an important say in the formation of the Ministry, through many writings and discussions and through his close relations with H. Wilson and R.H.S. Crossman. He wrote himself of his paper 'The case for a Ministry of Technology' (E.49): 'I believe that this memorandum had considerable influence in the setting up of the Ministry of Technology soon after the General Election of 1964'.
The folders CSAC 63.1.79/E.48-E.65 contain various writings, reports and correspondence relating to this period. Reference should also be made to CSAC 63.1.79/F.26-F.38 (The Trend Committee) since Blackett used much of the material and ideas contributed by scientific colleagues for the Royal Society's submission to the Trend Committee in the formation of his plans for the organisation of science and technology at ministerial level.

The topics covered here include university expansion (especially in science and technology); student intake, intelligence quotient, economic background and achievement; the financing and organisation of science and its relations with government.
Blackett's interest in these topics developed during the war and his service on the Barlow Committee (CSAC 63.1.79/F.9 - F.14). The items below fall into 2 main periods of activity: at Manchester C. 1945-51, and 1962-68 when formulation of ideas was encouraged both by the preparation for the 1964 General Election and by the institution of the Trend Committee. Many lectures and writings here and in Section H and his pressure on Labour Party leaders to devise a policy for government involvement with science and technology (see Section E) testify to Blackett's lifelong commitment to these matters. The training of scientists and engineers (referred to passim in his notes on QSEs), and the organisation of science both nationally and internationally were frequently referred to in his Anniversary Addresses as President of the Royal Society and formed the main theme of the 1969 Address (R.S. 119, See CSAC 63.1.79/F.49 - F.51).
Unfortunately, no manuscripts remain related to Blackett's long service on the National Research and Development Council (N.R.D.C.) (1949-64), but CSAC 63.1.79/F.23 - F.25 show his concern with the organisation and financing of science as a member of the Council of the Department of Scientific and Industrial Research (D.S.I.R.) from 1955 and Chairman of its Research Grants Committee 1956-60.
The material is presented as follows:

Blackett's earlier involvement with the problems of atomic weapons began in 1945 (see especially CSAC 63.1.79/D.148 - D.218).
It will be seen from the items below that he continued to voice his concern on the subject almost continuously until 1964 (cf. Lovell, Memoir, p.75). It is also clear how widely he lectured on this topic, to political, military, religious and academic audiences of varying composition and influence.
Several items in the list below represent published talks and lectures omitted from the Bibliography in the R.S. Memoir, and many more are unpublished.

OVERSEAS ACTIVITIES  CSAC 63.1.79/G.1-G.126  1944-1970

This Section comprises material relating specifically to India (CSAC 63.1.79/G.1 - G.55), and that concerned with matters more generally affecting developing countries (G.56 - G.126). The items under 'Visits and Conferences' include some wholly scientific meetings, but mainly refer to conferences on international co-operation, overseas aid, etc.
Blackett's involvement in India, from which sprang his general concern with the problems of developing countries, had a double origin. Through his researches on cosmic rays, he had become acquainted with Homi Bhabha, whose research establishments, and those of other scientific colleagues, he visited for lectures, conferences and discussions and whose plans - especially for atomic energy research in India - he encouraged (see his correspondence with Bhabha in CSAC 63.1.79/G.33). Secondly, his visit to India for the Indian Science Congress Association in 1947, and his consequent meeting with Nehru, led to his reports and advice to the Government of India on military and defence matters, using the technique of Operational Research developed in wartime (see CSAC 63.1.79/D.83 - D.125). See especially CSAC 63.1.79/G.1 - G.6, G.23, G.29 for material on this period, and for recollections of Nehru.
These two interests, fostered by frequent visits to India, encouraged a broadening of Blackett's concern to include problems of economic growth, distribution of wealth, overseas aid, population control and the like. In this later work, India remained the principal, though not the exclusive, example of the disparity between developed and undeveloped countries in Blackett's thinking.
Blackett's lasting sense of personal commitment to India can be seen from CSAC 63.1.79/G.23 - G.31, a folder probably made up in 1972, containing a list of his visits to India and his own collection of his earlier writings, together with some new linking material, intended as part of a book or section of collected writings devoted to the problems of India.
It will be see that relatively little material survives for the period CSAC 63.1.79/C. 1955-70, but reference to India is frequently made in lectures and writings in other sections of the collection, some of which were indeed given there. Repeated invitations in the correspondence for Blackett to visit, lecture or tour in India show how greatly his presence and advice were valued.
The material is presented as follows:

VISITS AND CONFERENCES  CSAC 63.1.79/G.85-G.126  1944-71

Arrangement: The material is presented chronologically.

It includes correspondence, travel arrangements, manuscripts or notes for lectures, papers, broadcasts, publications, etc.
This Section contains all surviving records of Blackett's attendance at international conferences, and of his foreign tours (See CSAC 63.1.79/G.23 - G.31 for visits to India), though it is clear that many other journeys were made and have left no documented evidence.
CSAC 63.1.79/G.85 - G.91 is of interest in recording Blackett's view of the episode in 1945 when he and other eminent British scientists were refused visas to visit Russia (see the note to these items).
The majority of the visits referred to in this Section were concerned with international co-operation, aid to developing countries, disarmament, etc.

Proposed visit to Russia  CSAC 63.1.79/G.85-G.91  June 1945

The visit was for the celebration of the 220th Anniversary of the Soviet Academy of Sciences.
Invitations to a large number of British representatives were issued and accepted (See CSAC 63.1.79/G.85 for a list of those invited, and Blackett's own invitation and acceptance). At the last moment, visas were refused for J.D. Bernal, P.M.S. Blackett, Sir Charles Darwin, P.A.M. Dirac, E.A. Milne, N.F. Mott, R.G.W. Norrish and E.K. Rideal, on the grounds that they could not be spared until the conclusion of hostilities with Japan.
Blackett led protests against this, by letters and interviews, but the ban remained.
The items below are kept in Blackett's folder, variously marked '1945 Russia', 'Visas Refused', 'Blackett Bernal Mott Norrish'; these notes were probably added at a late date in his career, indicating the lasting impression made on him by the matter, or perhaps the intention to refer to it in a proposed autobiography.

Some entries are accompanied by explanatory notes, and references are given to related matters in other Sections of the collection.
Several items include or refer to publications not listed in the Royal Society Bibliography. See especially CSAC 63.1.79/H.8, H.45, H.74, H.77, H.105, H.122, H.132, H.136, H.137, H.139. Many more are unpublished.

'Technology and World Advancement'  CSAC 63.1.79/H.57-H.73  1957

Blackett's Presidential Address to the British Association at its meeting in Dublin, 1957.
This was one of Blackett's most influential addresses, in which he developed his theme of the 'gap' between developed and under-developed countries, and the necessity for financial and technological support. The various drafts for the address (CSAC 63.1.79/H.62 - H.66) show Blackett's care in the preparation of the written and spoken versions of the address, and the folders of correspondence contain comments on the draft material (CSAC 63.1.79/H.57 - H.61), and also on the reception of the final product (CSAC 63.1.79/H.67 - H.68). The many requests for reprints, and the press-cuttings testify to the wide interest aroused by the address.
For other writings on these topics, see Sections F and G.
See Lovell, Memoir, pp.97-98.

Correspondence re Chadwick's 80th birthday dinner, including his reminiscences of Rutherford and his [Rutherford's] reluctance to develop nuclear physics in the 1930s. That was why I had to leave Cambridge... My last meeting with him was in early June 1936 and ended in almost a quarrel about the future of the Cavendish. I was quite right and he must have known it. He forgave me but it is an abiding sorrow to me that we should have parted with such a divergence of views'.

Hill, A.V.
Includes: Letter dated 12 August 1940, asking Blackett to act as adviser to General Pile, A.A. Command.
The letter opens: 'Apparently it was a case of love at first sight. After Pile, Newton and I had left the meeting last Friday Pile said to me that the obvious man for his job was you. I agree: it was clever of him to spot it in 3 minutes conversation. Is it conceivably possible you could take it on? It would be a very interesting job, and with all the knowledge you already have it would give you great scope to be useful. You would have a very free hand: and you ought to have a younger man (like Alan Hodgkin) as an understudy. You would be able to do for the A.A. Command what Tizard ought to have been given a chance to do for the RAF'.
The date and wording of this letter confirm 9 August as the most probable date for the meeting (see Lovell, Memoir, p.56).

I am pretty sure myself that the difficulties and delays about Tizard's mission to America in the autumn of 1940 were due to the same cause' [i.e. opposition by Cherwell].

Sullivan, W.
Includes photocopies of correspondence, December 1930- January 1931, exchanged between Einstein and William Barrett who had postulated a relation between the magnetic and rotational fields of the earth.
Blackett's letter of September 1973 gives an account of his own involvement in a similar hypothesis, as follows:
'Several years ago I thought that this was a plausible theory and I did a lot of experimental work to find out whether there was such a relationship. In fact all my work in this field proved wrong.
If you want to recover what many of us thought in the early 1930's then you might read my article in Nature ("The Magnetic Field of Massive Rotating Bodies", Nature Vol. 159, May 17, 1947) about the hypothetical relationship between the magnetic and rotational fields. Further when it was shown that the earth's magnetic field reverses several times in a million years at the same time at all places on the earth's surface it was clear that the earth's field must be originating from the dipole of an atom.
What a lot has happened since we met. I was very sad when all my thoughts and work on the rotation body proved false. However there were several very important conclusions: firstly, the proof of the reversal of the magnetic field sets enormous problems on the motion of the earth core. Then the view was that there exists in the core some very complicated phenomena and that these together in some way create this remarkable phenomenon of reversal of the fields so frequently in geological time. The failure of the experiment on rotational bodies led me to design a magnenometer of great sensitivity and this proved very valuable for the study of the magnetic fields on the earth's mantle. These magnetic studies after several years have played a major part in the development of continental drift and, to use the present jargon, to create a system of geological plates floating near the surface of the earth.'

Correspondence Swinton, P. (Lord Swinton)  CSAC 63.1.79/J.99  1936

2 letters re the Committee for the Scientific Survey of Air Defence (CSSAD) (The 'Tizard Committee').
The first of these letters (16 July 1936) opens:
'I have your letter of the 15th of July, and I appreciate the way in which you have written to me personally. I should very much like to have a talk to you and to Professor Hill next week ...'
The second letter (3 September 1936) reads:
'I have received the resignations of three of the unofficial members of the Committee for the Scientific Survey of Air Defence. In these circumstances I have no option but to dissolve the Committee as at present constituted.'
The folder includes a press-cutting of a later article by R.W. Clark (1968) stating that the resignation followed immediately on the controversial meeting on 15 July, but this was not the case. Blackett and Hill wrote to express their disquiet but did not resign until August.

Tizard, H.T.; Correspondence of various dates  CSAC 63.1.79/J.105  1940-1958

Letter from Tizard to all members of Committee for Scientific Survey of Air Warfare, 26 June 1940, resigning as Scientific Adviser to the Chief of the Air Staff, and as Chairman of the Committee.
In this letter Tizard states: 'With the change of Government matters have become worse in this respect, not better. There are too many advisers and too much conflicting advice; responsibilities are not clear cut, and in consequence action is slow... I have therefore resigned my post as Scientific Adviser, and as Chairman of the Committee, I have also told the Secretary of State that I do not think that the Committee can continue to be of much help unless there is a change in the organisation.'
Also included is the ms. draft of Blackett's letter to Archibald Sinclair (Secretary of State for Air), resigning from the Committee ('I am in entire agreement with Sir Henry Tizard that the Committee cannot function usefully under the present conditions') and arguing strongly for Tizard to be given 'a position of high executive authority in relation to the development (sic) and operational trials of new weapons', 30 June 1940; and letter from Sinclair accepting resignation 'with great regret'.
The terms of both Tizard's and Blackett's letters make clear that it was the formation of Churchill's Government, and the increased influence of Cherwell, which led to the resignations, and the end of the Committee.
2 letters, July (1 p. only) and August 1943.
1 letter, March 1945.
Correspondence, September 1958, on atomic weapons.
