The surviving papers cover almost every aspect of Bullard's career. The chief lacunae are his wartime papers which he destroyed in 1945 and his official papers at Toronto and the National Physical Laboratory. There are biographical and personal material, diaries, personal and family correspondence and photographs, records of the Cambridge Department of Geodesy and Geophysics including the original correspondence leading up to its foundation in 1921, and documentation of his connection with the University of California, chiefly the Scripps Institution of Oceanography. The largest body of material relates to Bullard's many research interests from early work on gravity to the last uncompleted book on energy sources and nuclear waste disposal, and includes full documentation for his work on dynamo theory and on computing applications. There is much material on Bullard's service on committees and as consultant, and relating to learned societies and professional organisations, to publications, lectures and broadcasts, and to visits and conferences. Bullard's surviving scientific correspondence is somewhat disappointing and contains a high proportion of material dating from his later years.

Scope and Content
Administrative / Biographical History
Bullard was born in Norwich and educated at Repton School and Clare College, Cambridge where he read natural sciences, 1926-1929. His first graduate research was at the Cavendish Laboratory, Cambridge working under the direction of P.M.S. Blackett and in collaboration with H.S.W. Massey, on electron scattering in gases. In 1931, partly because of the economic depression, he accepted a post under G.P. Lenox-Conyngham in the Department of Geodesy and Geophysics at Cambridge. Here he worked on geophysical instrument design and development, gravity determination in Britain and Africa, explosion seismology including the first British expeditions to study the Atlantic seafloor, and heat-flow in South Africa bore-holes. During the Second World War he was seconded to the Admiralty, working on anti-mine protection, operational research and intelligence. After the war he returned to Cambridge but in 1947 he moved to Toronto University as Professor of Physics and while there, but on a summer vacation visit to the Scripps Institution of Oceanography, La Jolla, California he did some of his most important work on the design of equipment for the measurement of heat-flow at sea. In 1950 he returned to Britain as Director of the National Physical Laboratory, Teddington where despite administrative and official duties he continued to work on marine heat-flow, building apparatus and taking part in sea-going expeditions, and also developed his dynamo theory of terrestrial magnetism.
In 1956 Bullard returned to the Department of Geodesy and Geophysics, Cambridge as Assistant Director of Research (Reader in Geophysics 1960, Professor 1964). His research interests now included continental drift and plate tectonics as well as continuing work in seismology and geomagnetism, and the development of computer programs for processing large amounts of observational data. During this period he was very active as consultant and adviser to Government Departments (notably the Admiralty, Foreign Office, Ministries of Defence, Science and Supply), to professional and learned societies such as the Institute of Physics, Royal Society and the International Union of Geodesy and Geophysics, and to industrial firms principally Shell and IBM UK. He was also a founder member of the Natural Environment Research Council. On retirement from Cambridge in 1974 Bullard moved to the Scripps Institution of Oceanography where he continued his research and took part in expeditions and teaching and lecturing programmes. He added a last research topic to his interests - energy sources and nuclear waste disposal - in his capacity as consultant to the Jet Propulsion Laboratory of the California Institute of Technology. Bullard was elected FRS in 1941 (Bakerian Lecture 1967, Hughes Medal 1953, Royal Medal 1975) and was knighted in 1953.
