Administrative history:
Thomson was born in Cambridge in 1892, into a family of scientific distinction on both sides. His father, Sir Joseph Thomson (always known as 'J.J.'), was one of the foremost physicists of the day, Director of the Cavendish Laboratory, Cambridge, and in 1906 awarded the Nobel Prize for Physics for his discovery of the electron. His son George was much guided and influenced by his father, conducting early collaborative research with him and having access through him to current work on the frontiers of knowledge, as his later historical writings frequently testify. Thomson's collaboration with his father continued for many years and included joint work on the Third (1928) Edition of Conduction of Electricity through Gases.
After education at the Perse School and Trinity College, Cambridge, Thomson began research in 1913 at the Cavendish Laboratory under his father's supervision, and was elected a Fellow of Corpus Christi College in 1914. During the First World War he was attached to the Royal Flying Corps at the Royal Aircraft Factory (later Establishment) at Farnborough, where he was a member of the famous 'Chudleigh Mess' and formed lasting friendships with F.W. Aston, W.S. Farren, B.M. Jones, F.A. Lindemann (later Lord Cherwell), G.I. Taylor and others.
At the end of the War he returned to Cambridge, and in 1922 was appointed Professor of Natural Philosophy at the University of Aberdeen. Here his most famous work was done, on electron diffraction by thin films (1926-28), for which he shared with C.J. Davisson the Nobel Prize for Physics in 1937.
In 1930, after a visit to America lecturing and working at Cornell, Thomson, now a Fellow of the Royal Society, moved to London as Professor of Physics at Imperial College. He continued work on electron diffraction and tried to develop it as a research tool for the study of surfaces, and also encouraged electron microscopy. A protracted illness which declared itself early in 1936 seriously interrupted his experimental work and marked the effective end of his work on electrons. Instead, he pursued the interest in nuclear physics begun a few years earlier, and in 1939 was quick to see the possible military implications of current work in nuclear fission. His professional knowledge, and his personal acquaintance with leading scientists and government advisers enabled him to initiate investigations, especially as (from April 1940) Chairman of the MAUD Committee which reported on the feasibility of an atomic weapon.
During the Second World War, subsequent to his work on the MAUD Committee, and after two years at the Royal Aircraft Establishment, Farnborough, Thomson was sent as Scientific Liaison Officer to Canada. At this time, his wife Kathleen was seriously ill in America; her death at the end of 1941 was a great blow to him. He remained in Canada until summer 1942 after which he returned to Britain to become Deputy Chairman of the Radio Board (1942-43) and Scientific Adviser to the Air Ministry (1943-44). He resigned this post in December 1944 to resume work at Imperial College. He was knighted in 1943.
His scientific interests now centred on the study of cosmic rays and mesons, and on nuclear fusion - itself a development of a theory of an electrodeless discharge put forward by 'J.J.'. Under Thomson's guidance, work on an electrodeless torus proceeded at Imperial College and was provisionally patented in 1946; the team subsequently transferred to the A.E.I. laboratories at Aldermaston, while similar work was also in progress at Harwell. Both groups produced an apparatus - SCEPTRE at A.E.I., ZETA at Harwell - which attracted much attention when they were brought to the notice of the general public in 1958.
In 1952 Thomson returned to Corpus Christi College, Cambridge, as Master; he remained there until 1962 and spent his retirement in Cambridge, where he died in 1975.

The material includes notebooks, manuscript notes and drafts, drafts for lectures and papers (many unpublished or additional to those listed in the Bibliography compiled for the Royal Society Memoir of Thomson), photographs and slides of experimental results, and correspondence.
Of considerable interest are the drafts and text of Thomson's autobiography covering his career to 1966; this document, which he had written primarily for his family, is included at CSAC 75.5.80/A.2 - A.14 and has, with permission, been drawn upon in compiling some of the catalogue entries. It is an important source of information for some of the 'gaps' in the surviving manuscripts, particularly for such matters as Thomson's activities in the Second World War (other than the MAUD Committee), his many foreign visits and his public commitments. In his introduction to the autobiography, Thomson mentions his inability to write adequately of his wife Kathleen, and of his hope to compile a selection of her letters to him; bound copies of the autobiography, and of the letters, have been made available by Mr. D.P. Thomson and appear at CSAC 75.5.80/A.14, A.14A respectively.
Thomson's scientific research on electron diffraction is well documented by notebooks, lectures and slides; his contribution to thermonuclear research, on which he was able to publish very little because of the demands of security, survives mainly in the form of manuscript notes and drafts (see Section E). Unfortunately, it is clear that much has been lost of the early correspondence on electron diffraction.
Thomson's service to the Royal Society, The Institute of Physics, the British Association and many other learned societies, is also very scantily documented.
Thomson's own distinguished contribution to scientific knowledge, together with his admiration for his father and early acquaintance with eminent men of science, made him always aware of the history of science and its practitioners. He wrote and lectured widely on these subjects, often for anniversary celebrations of various kinds, and also contributed many obituary tributes for individual scientists, many of them his personal friends. He frequently assembled information and recollections additional to those which appeared in the final publication, but which survive in the collection. Material relating to his historical and biographical writings on 'J.J.' can be found in the collection of papers of J.J. Thomson (CSAC no. 74/4/80) in the Library of Trinity College, Cambridge.
In addition to an historical awareness, Thomson was also conscious of the impact of science on many aspects of life and thought. Section H groups together his lectures and writings on science-related topics of this kind; it includes inter alia material on his work for the Voluntary Euthanasia Society which occupied much of his interest in his later years.

Autobiographical material.  CSAC 75.5.80/A.2-A.14  [n.d.]

The main source is Thomson's draft autobiography (CSAC 75.5.80/A.2-A.12) in a series of notebooks and loose pages, most autograph manuscript but including some typed-up sequences. Some additional notes and material are included in A. 13.
Of his autobiography, Thomson wrote (CSAC 75.5.80/A.2): 'This book has been written for my children and grandchildren, in the hopes that the former may be interested in reading of events they remember or have heard about and that the latter as they grow up may enjoy hearing about the homes in which their parents lived, and the family into which they have been born. It is not meant for publication, but I have no objection to suitable extracts being published at John's discretion [Sir John Adam Thomson, KCMG], or at David's [Mr. D.P. Thomson] if John happens to be out of England. A copy may be lent to whoever the Royal Society selects to write the usual biographical memoir. I did not feel able to write about Kathleen [Kathleen Buchanan, née Adam Smith], but hope to have a few copies made of a selection of her letters which may give a better idea of her than I can hope to do.'
A bound copy of the complete autobiography appears of CSAC 75.5.80/A.14; a volume of Kathleen Thomson's selected letters is included at CSAC 75.5.80/A.14A.

SECTION B EARLY NOTEBOOKS AND RESEARCH, 1905 - 1922  CSAC 75.5.80/B.1 - B.39  [n.d.]

Related information: See also CSAC 75.5.80/D.17 in the collection of J.J. Thomson (CSAC 74/4/80, in Trinity College, Cambridge), a notebook containing mathematics notes from Thomson's undergraduate days which he later used for his father's biography.

This Section documents aspects of Thomson's education at the Perse School and Trinity College, Cambridge, and his early research conducted at the Cavendish Laboratory under the direction of his father immediately before and after the First World War.
The material is presented as follows:
CSAC 75.5.80/B.1 - B.10 School notebooks 1905-10
CSAC 75.5.80/B.11 - B.31 Cambridge University. Undergraduate notebooks and early research 1910-14
CSAC 75.5.80/B.32 - B.39 Research in Cambridge 1919-22
Many of Thomson's notebooks were re-used at different periods of his life; sometimes the old pages were torn out, sometimes he restarted from the back of the book. Occasionally a single notebook contains very diverse material, such as CSAC 75.5.80/B.2 (school exercises at one end and personal accounts for 1924-26 at the other) and CSAC 75.5.80/E.60 (school exercises followed by notes on thermonuclear research).

School Notebooks 1905-10  CSAC 75.5.80/B.1-B.10  [n.d.]

The earliest of these dates from Thomson's first year at the Perse School, Cambridge, and the subjects covered include English literature and the classics as well as science and mathematics. During his last year at school he attended A. Wood's lectures at Cambridge University, and his notes on these appear at CSAC 75.5.80/B.5 - B.7.

In his autobiography (CSAC 75.5.80/A.4) Thomson recalls that he and five others went to G.A. Herman three times a week for private coaching. 'It cost nine guineas a term, quite a sum in those days... The coaching was really a set of lectures, but examples were set and each morning he went through those set last time... The actual lecture was given fairly fast and our notes were often incomplete, but we used to meet afterwards in someone's rooms and learned a lot in the process of sorting them out. If the lectures had been free we should probably not have taken this trouble, to our loss.'

Administrative history:
In 1922 Thomson was appointed as Professor of Natural Philosophy in the University of Aberdeen, where he remained until 1930 when he went to succeed H.L. Callendar as Professor of Physics at Imperial College, London. It was at Aberdeen that Thomson did his famous electron diffraction experiments which led to his sharing the Nobel Prize for Physics with C.J. Davisson in 1937. The research notes and notebooks in this Section document much of this work together with his earlier research at Aberdeen on positive rays.
On moving to Imperial College Thomson continued to study electron diffraction and tried to develop it as a technique for the study of surfaces. His experimental work was interrupted by illness at the beginning of 1936 by which time he was already becoming interested in the study of neutrons which had been introduced to Imperial College by P. B. Moon soon after his arrival (see Section D); it was to this study that he returned when he was able to resume work in 1938.
Lectures on electron diffraction are to be found in Sections F and G. See also Section K for slides of electron diffraction experiments.

The material is divided into two sections, each with an introductory note.
CSAC 75.5.80/D.1 - D.28 Nuclear physics and the MAUD Committee
CSAC 75.5.80/D.29 - D.78 Second World War: other activities


Administrative history:
According to Thomson's autobiography (CSAC 75.5.80/A.7) his interest in nuclear physics stemmed from the arrival of P.B. Moon at Imperial College in 'about 1932'. Moon introduced the study of neutrons to the laboratory soon after their discovery by Chadwick, and Thomson's early work on this subject is documented at CSAC 75.5.80/D.1 - D.4; on his return to Imperial College in 1938 after two years of illness he collaborated with Moon in attempts to measure slow-neutron velocity distributions and absorption coefficients (see CSAC 75.5.80/D.5, D.6).
In the spring of 1939 work on nuclear fission in various parts of the world suggested that the release of an enormous amount of energy from uranium by means of a chain reaction might be a real possibility. Thomson was quick to realise the military implications of this. He asked Air Marshal Sir Wilfred Freeman for a ton of uranium oxide for conducting experiments at Imperial College and proceeded to establish that a chain reaction could not be easily obtained using natural uranium oxide and ordinary water or paraffin.
The work was interrupted when Thomson went to Farnborough on the outbreak of the Second World War (see CSAC 75.5.80/D.30 - D.34), but his interest in the problem was reawakened in early 1940 by the claim of O. Frisch and R. Peierls that the chain reaction could be obtained by using pure U²³5. This led to the formation of the MAUD Committee which had its first meeting in April 1940 (see CSAC 75.5.80/D.10).

The following papers contain some papers contain some of Thomson's early research notes on experiments with neutrons and one folder of calculations re uranium (CSAC 75.5.80/D.8) as well as copies of the MAUD Committee reports of July 1940, various notes of meetings and some correspondence, both contemporary and later. Other material on the MAUD Committee is held at Churchill College, Cambridge, where Thomson deposited a small collection of papers at the request of Sir John Cockcroft in 1966. Permission to consult these should be obtained from The Archivist, Churchill College, Cambridge.

Administrative history:
At the beginning of the Second World War Thomson went to work at the Royal Aircraft Establishment, Farnborough. His wife, Kathleen, and their four children were sent to America for safety during the threat of invasion in the summer of 1940, but in 1941 Kathleen became gravely ill and at his own request Thomson was transferred to Ottawa as Scientific Liaison Officer in order to be nearer to her. She died at the end of 1941 but Thomson continued to work in Canada for a further six months, returning to England in the summer of 1942. He then spent a year as Deputy Chairman of the Radio Board and a further year as Scientific Adviser to the Air Ministry, returning to take up his duties at Imperial College at the end of 1944.

The documentation for this period is sparse. There is very little in the way of correspondence, and less to illustrate Thomson's daily activities, with the exception of the visits he made to various establishments in Canada and the U.S.A. for which a series of ms. and typescript reports is to be found at CSAC 75.5.80/D.35 - D.59.

Related information: See CSAC 75.5.80/F.150 - F.209 for further material on thermonuclear energy.

Administrative history:
'By the beginning of 1946,' wrote Thomson in his autobiography (CSAC 75.5.80/A.9) 'my own interest was turning to the possibility of the controlled emission of nuclear power from the (relatively) heavy isotopes of hydrogen; what is now called thermonuclear energy.'
The initial work was done at Imperial College in collaboration with M. Blackman with whom Thomson filed a provisional patent for 'Improvements in or relating to high temperature systems' in 1946 (see CSAC 75.5.80/E.75). By 1947 considerable progress had been made in theoretical and small-scale experimental research, and Thomson felt ready to initiate a full-scale project, requiring more extensive facilities than Imperial College could provide. Related research was already in progress at the Atomic Energy Research Establishment (A.E.R.E.), Harwell, so Thomson approached T.E. Allibone, Director of the newly-established Research Laboratory of Associated Electrical Industries Limited (A.E.I.) at Aldermaston. Some aspects of the ensuing negotiations are documented in CSAC 75.5.80/E.88 - E.90; the Imperial College group finally moved to Aldermoston in 1951 and a programme of research was started which led to the production of the apparatus known as Sceptre Ill in autumn 1957. The Aldermaston group worked in close cooperation with Harwell throughout its existence; several minutes of progress meetings, at which Thomson was also in regular attendance, are to be found at CSAC 75.5.80/E.91 - E.105.
Most of the thermonuclear work ceased to be secret after the simultaneous publication in January 1958 of accounts of the work with Sceptre Ill and Zeta, a similar apparatus produced by Harwell. Thomson subsequently became less directly involved with thermonuclear research and his active participation finally ceased in 1963 when A.E.I. decided to close down the Aldermaston Laboratory.

The material is divided as follows:
CSAC 75.5.80/E.1 - E.70 Notes, drafts and calculations, 1946-59
CSAC 75.5.80/E.71 - E.87 Patent applications relating to thermonuclear energy, 1946-59
CSAC 75.5.80/E.88 - E.90 Correspondence and papers, 1946-52
CSAC 75.5.80/E.91 - E.105 Minutes of meetings, 1952-63
CSAC 75.5.80/E.106-E.111 Correspondence, 1958-63
CSAC 75.5.80/E.112-E.143 Research reports and lectures by others
CSAC 75.5.80/E.144, E.145 Miscellaneous other material
The survival of Thomson's research notes and drafts for this period (CSAC 75.5.80/E.1 - E.70) is particularly interesting in view of the secrecy restrictions which allowed him to publish so little (but see CSAC 75.5.80/F.114, F.115), although some of his drafts were reproduced for limited circulation as Harwell research reports (see, e.g., CSAC 75.5.80/E.34, E.35).

CSAC 75.5.80/F.1 - F.33 University lectures (at Cambridge, Aberdeen, and Imperial College London)
CSAC 75.5.80/F.34 - F.149 Physics
CSAC 75.5.80/F.150 - F.209 Nuclear and Thermonuclear Energy
The material in each of the sub-sections is presented in approximate chronological order, though Thomson rarely dated his early notes and drafts; in many cases they can only be roughly dated on internal evidence. The 'University Lectures', especially those given at Aberdeen, were often cannibalised and updated for use at Imperial College, London, and no firm boundary can be drawn except for the post-Second World War lectures at London on cosmic rays and nuclear physics.
The lectures and writings on 'Physics', CSAC 75.5.80/F.34 - F.149, naturally focus on Thomson's own research interests and discoveries. CSAC 75.5.80/F.36 - CSAC 75.5.80/F.61 are almost all on electron diffraction, his own experimental research (for which he shared with C.J. Davisson the Nobel Prize for Physics in 1937) and the wave-particle theory of matter; the number of these, and the range of places at which Thomson was asked to speak, show the international recognition of his work. Several items, CSAC 75.5.80/F.66 - F.77, deal with the practical applications of electron diffraction, and the electron microscope, as tools of research.
After the Second World War, Thomson continued to write and lecture on the electron, and also on cosmic rays, mesons, and atomic structure. The advent of nuclear, and later of thermonuclear power, however, provided the chief matter of his scientific research and publications. CSAC 75.5.80/F.120 - F.168 are a crowded cluster of items - including several broadcasts - on the nature and control of nuclear energy, followed by a similar output at CSAC 75.5.80/F.169 - F.174 on the then new implications of the hydrogen bomb. These problems continue to recur throughout the remainder of the material, some linked with the opening of atomic power stations (CSAC 75.5.80/F.188 et seq.).
Thomson himself made a distinguished contribution to research on nuclear fusion from the early 1940s, and played a part in the development of thermonuclear research at Harwell and A.E.I. Most of his work was not released for publication, but the public announcement of Zeta in 1958 led to many lectures and articles by him, some technical and some more popular, on thermonuclear questions (CSAC 75.5.80/F.193 - F.205).
The material in this Section is only rarely accompanied by research material or by related correspondence - it should be consulted in conjunction with the notebooks and documents in Sections C and E.
Although several items naturally contain autobiographical and historical reflections by Thomson on his experience of twentieth-century physics, his explicit writings on the history of physics and physicists, and his more general ideas on the methods, purpose and implications of science have been grouped in Sections G and H respectively.

CSAC 75.5.80/H.160, H.161 Shorter talks.
The material in this Section includes notes, lectures, broadcasts and publications, and a little related correspondence.
There is inevitably some overlap with material assigned to other Sections, e.g., CSAC 75.5.80/F.150 - F.209 on the effects of nuclear and thermonuclear power. The main criterion is that Section H contains the reflections of a non-professional on fields of activity affected by developments in his own profession.
Thomson was always interested in the wider aspects of science. Some of the talks on the purposes and methods of science, and of its relation with religion, appear to date from the late 1920s or early 1930s; his lectures in America and Canada, 1929-30, are known to have included a talk on the philosophical implications of the recent discoveries in physics.
The surviving material represents two main strands in Thomson's thinking. One of these is concerned with the practical aspects of science, its impact on society, its funding and guidance, its relations with government institutions, its influence on individual lives in peace and war. His book 'The foreseeable future' (1955, widely translated) is the best known summation of these ideas, but the entries below indicate the number and also the time-span of his writings and lectures on similar topics.
The second aspect relates to abstract and philosophical concepts. From general discussion of scientific and religious criteria of truth and choice, Thomson was led to examine determinism in human affairs, and randomness and predictability in the human brain. Much of his later work is concerned with these matters.
The two threads may be said to come together in Thomson's work for the Voluntary Euthanasia Society. Here he seems to have felt that for both sociological and philosophical reasons an individual may, and should, exercise the power of choice over his life. Thomson gave much attention to this in his later years, and planned an extended work on the subject (CSAC 75.5.80/H.126 - H.138), left unpublished at his death.

SECTION J CORRESPONDENCE  CSAC 75.5.80/J.1 - J.134  [n.d.]

The main sequence of correspondence (CSAC 75.5.80/J.1 - J.124) is presented alphabetically, dated, and with an indication of any material of particular scientific or biographical interest. Most of the correspondence is with individuals, but some societies and organisations are also included.
There are few very substantial exchanges and it is clear that there are considerable gaps in the material; in particular there is very little early correspondence on electron diffraction, and the only letter in the collection from J.J. Thomson is at CSAC 75.5.80/C.3.
CSAC 75.5.80/J.125 - J.134 consists of shorter correspondence, mostly unindexed.
