The bound volumes of Thomson's autobiography (A.14), of his published papers (A.51, A.52), and of his own selection of letters from his wife Kathleen (A.14A), are included by courtesy of Mr. D.P. Thomson. The photocopy of the letter by Thomson at J.119 has kindly been made available by the Right Reverend the Bishop of Ely. CAREER AND WORK OF G.P. THOMSON 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, Factory (later Establishment) at Farnborough, where he was a member of the famous At the end of the War he returned to Cambridge, and in 1922 was most famous work was done, on electron diffraction by thin films (1926-28), for which After education at the Perse School and Trinity College, Cambridge, 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. work on the Third (1928) Edition of Conduction of Electricity through Gases. Thomson's collaboration with his father continued for many years and included joint Cambridge, and in 1906 awarded the Nobel Prize for Physics for his discovery of the Thomson began research in 1913 at the Cavendish Laboratory under his father's super- he shared with C.J. Davisson the Nobel Prize for Physics in 1937. appointed Professor of Natural Philosophy at the University of Aberdeen. Here his vision, 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 ‘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. G.P. Thomson CSAC 75/5/80 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 experi- mental 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 at Imperial College. He was knighted in 1943. His scientific interests now centred on the study of cosmic rays and to him. 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 in America; her death at the end of 1941 was a great blow He remained in Canada until summer 1942 after which he returned to Britain 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; subsequently transferred to the A.E.1. laboratories at Aldermaston, while similar work Both groups produced an apparatus - SCEPTRE at was also in progress at Harwell.

G.P. Thomson CSAC 75/5/80 DESCRIPTION OF THE COLLECTION 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 A.2 - A.14 and has, with permission, been drawn upon in compiling some of the catalogue entries. is an important source of information for some of the 'gaps' in the surviving manuscripts, particularly for It 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 A.14, A.14A respectively.

He wrote and lectured widely on these subjects, often for anniversary celebrations of various kinds, and also contributed many obituary tributes for individual scientists, Thomson's own distinguished contribution to scientific knowledge, many of them his personal friends. G.P. Thomson CSAC 75/5/80 6 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. Sectiom 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. LOCATIONS OF OTHER MATERIAL Thomson's original electron diffraction camera was deposited in the Science Museum, London, in 1948 (see J.107). Material relating to the Thomson and Paget families remains in family hands. relating to electron diffraction, is gratefully acknowledged. ENQUIRIES ACKNOW LEDGEMENT The help of Dr. M.J.

The material is presented as follows: B.1 -B.10 School notebooks 1905-10 B.11-B.31 Cambridge University. notebooks and early research 1910-14 Undergraduate 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 B.2 (school exercises at one end and personal accounts for 1924-26 at the other) and E.60 (school exercises followed by notes on thermo- nuclear research).

Thomson CSAC 75/5/80 SECTION F SCIENTIFIC LECTURES AND WRITINGS F.1 - F.209 Fol@ F.33 University lectures (at Cambridge, Aberdeen, and Imperial College London) F.34 - F.149 Physics 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', F.34 - F.149, naturally focus on Thomson's own research interests and discoveries. F.36 - F.61 are almost 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. F.120 - F.168 area crowded cluster of items - including several broadcasts - on the nature and control scope, as tools of research. speak, show the international recognition of his work. Several items, F.66 - F.77, 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 deal with the practical applications of electron diffraction, and the electron micro- (F.188 et seq.). the remainder of the material, some linked with the opening of atomic power stations of nuclear energy, followed by a similar output at F.169 - F.174 on the then new implications of the hydrogen bomb. These problems continue to recur throughout G.P. Thomson CSAC 75/5/80 Scientific lectures and writings Thomson himself made a distinguished contribution to research on nuclear fusion from the early 1940s, and played a part in the development of thermo- nuclear research at Harwell and A.E.1. 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 (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.

There is inevitably some overlap with material assigned to other Sections, e.g., F.150 - F.209 on the effects of nuclear and thermonuclear power. tions of the recent discoveries in physics. The surviving material represents two main strands in Thomson's Thomson was always interested in the wider aspects of science. fields of activity affected by developments in his own profession. 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 The main criterion is that Section H contains the reflections of a non-professional on and Canada, 1929-30, are known to have included a talk on the philosophical implica- similar topics. 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 G.P. Thomson CSAC 75/5/80 Science-related interests 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 aitention to this in his later years, and planned an extended work on the subject (H.126 - H.138), left un- published at his death.
