Papers and correspondence of Sir George Paget Thomson, 1892-1975

Scope and Content

The papers are extensive and cover many aspects of Thomson's career and research. They include his unpublished autobiography, school and undergraduate notebooks, notebooks, drafts and photographs documenting his work on electron diffraction, manuscript notes and drafts on thermonuclear research, extensive notes and drafts for talks and writings on the history and social aspects of science, and also material relating to Thomson's involvement with the Voluntary Euthanasia Society. Unfortunately the full range of his correspondence (including that on electron diffraction) has not survived.

Administrative / Biographical History

Thomson was born into a family of great scientific distinction. His father, Sir Joseph Thomson, 'J.J.', was one of the foremost physicists of the day and a great influence on him. Thomson, 'G.P.' as he was always known, was educated at the Perse School and Trinity College, Cambridge where he read mathematics and physics. He then began research at the Cavendish Laboratory under his father's supervision, and was elected Fellow and Mathematical Lecturer at Corpus Christi College, Cambridge in 1914. After a period of service in France with The Queen's Regiment he was attached to the Royal Flying Corps at the Royal Aircraft Factory (later Establishment), 1915-1919.

After the First World War he returned to Cambridge to continue his research 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. He was Professor of Physics at Imperial College, London, 1930-1952, with secondment during the Second World War on various official duties including the Chairmanship of the Maud Committee which reported on the feasibility of an atomic weapon. Later, he made significant contributions to research on thermonuclear reactions. In 1952 Thomson returned to Corpus Christi College as Master. He remained there until 1962 and spent his retirement in Cambridge. He was elected FRS in 1930 (Bakerian Lecture 1948, Rutherford Memorial Lecture 1964, Hughes Medal 1939, Royal Medal 1949) and was awarded the 1937 Nobel Prize for Physics (jointly with C.J. Davisson) for their experimental discovery of the diffraction of electrons by crystals. He was knighted in 1943.
