Fowler, a colleague of Powell. OUTLINE OF THE CAREER OF CECIL FRANK POWELL Powell was born in Tonbridge, Kent in 1903 and educated at Judd School in Tonbridge and Sidney Sussex College, Cambridge. He began his research career in physics at the Cavendish Laboratory Cambridge, working with C.T.R. Wilson, but in 1928 he moved to the University of Bristol as a research assistant to A.M. Tyndall, Henry Overton Wills Professor of Physics. of DESCRIPTION OF THE COLLECTION the photographic method of studying nuclear processes and his discoveries regarding mesons made with this method. Powell spent the rest his career at Bristol as Lecturer, 1931-1946, Reader, 1946-1948, Melville Wills Professor of Physics, 1948-1963, and Henry Overton Wills Professor and Director of the H.H. Wills Laboratory, 1964-1969. Powell always encouraged an international approach to research, and from 1950 played an increasingly large part in political and international science, as Chairman of the World Federation of Scientific Workers, 1956-1959, Chairman of the Science Policy Committee CERN, 1961-1963, and in many other capacities. He was one of the signatories of the Russell-Einstein manifesto of July 1955, and presided at the plenary session of the first Pugwash Conference in July 1957. Powell was a pioneer in particle physics, best known for his discovery of the pion. He was elected FRS in 1949 (Hughes Medal 1949, Royal Medal 1961) and was awarded the 1950 Nobel Prize for Physics for his development of Throughout this catalogue titles in inverted These papers and correspondence of Cecil Frank Powell supplement those catalogued in 1974 (CSAC catalogue 12/6/74) and 1986 (CSAC catalogue 111/2/86.), both deposited in the Library, University of Bristol. The collection is presented as in the list of contents. The material covers the period 1941-2002. Material supplementary to the previous catalogues has been found for Sections A (Biographical), B (Balloon and aeroplane flights), C (Publications), E (Correspondence) and F (Research). Section G, Visits and conferences, is a completely new section. C. F. Powell (Second supplement) NCUACS 114/13/02 commas indicate the original typescript or manuscript titles of Powell's folders. These have not generally been retained. Section A, Biographical, includes a large-format photograph album featuring balloon flights from the University of Bristol and Italy 1949-1961, and group photographs of Powell's Cosmic Ray research team including visiting scientists and students at the University of Bristol between 1949 and 1960. Those featured include Powell and his wife Isobel Powell, P.H. Fowler, J.H. Davies, D.H. Perkins and H. Heitler. It is numbered to follow on from catalogue CSAC 111/2/86. Section B, Balloon and aeroplane flights, is arranged in alphabetical order based on Powell's own folder titles and comprises material on flight expeditions between 1953 and 1971. It is one of the larger sections of the catalogue and presents a good record of the research of Powell and his team (in particular P.H. Fowler). It includes correspondence, photographs, technical drawings, maps, memoranda and reports on balloon flights in Bristol, Cardington (Bedfordshire), Scotland, Sardinia, Hyderabad (India), New Mexico, Victoria (Texas) and Sioux Falls (Minnesota) 1953-1971, and aeroplane flights on Comet, Vulcan and VC10 aircraft between 1957 and 1964. Material also documents balloon making, collaboration with foreign universities and institutions, technical support with naval and air ministries, meteorological services in the United Kingdom and relations with NATO. At the end of the sequence is a little photographic material. The section is numbered to follow on from catalogue CSAC 11 1/2/86. alphabetical sequence as originally arranged, running from A to S. The sequence precedes that running from S-Z, which is to be found in catalogue CSAC 111/2/86. Section C, Publications, is slight and includes documentation of four papers only. Most of the Section E, Correspondence, forms the largest section of the collection. It is presented in an cancer treatment written by Powell and P.H. Fowler. It is numbered to follow on from catalogue material relates to a paper entitled ‘Therapeutic Applications of Beam of Negative Pion Mesons' on issues of atomic energy and nuclear weapons, exhibitions, publications of papers and proceedings of not exclusively correspondence, covers a wide range of topics from collaboration on research and expeditions with national and foreign universities, to dealings with governmental bodies in the UK including the Department of Scientific and Industrial Research and the United Kingdom Atomic Energy Authority and supra-national bodies abroad such as NATO. There is also material relating to scientific societies and organisations such as the Royal Society and CERN, and national laboratories including the Rutherford and Culham Laboratories and the National Physical Laboratory. There is also material on the supply of cosmic ray research material by commercial companies, balloon flights expeditions and analysis of exposed emulsion stacks, the CSAC 111/2/86. The material, which is C. F. Powell (Second supplement) NCUACS 114/13/02 conferences. It is numbered to follow on from catalogue CSAC 111/2/86, although as indicated above, the sequence presented in this catalogue precedes it in the alphabet. Section F, Research, is not substantial. It is mainly related to collaboration on K- research with foreign universities and institutions. There is also material relating to n-p scattering and neutrino experiments. This material follows on from catalogue CSAC 12/6/74. Section G, Visits and conferences, covers the period from 1960 to 1965. Powell went to only some of the conferences but he retained material relating to many that he did not attend, some of which were attended by other members of his team. Conferences of particular significance are the series of Rochester conferences on High Energy Physics, the Ultra High Energy Nuclear Physics conference in Bristol (1963), various CERN conferences and the 1965 International Union of Pure and Applied Physics conference. There is also an index of correspondents. ACKNOWLEDGEMENTS Thanks are due to Mrs Rosemary Fowler for assistance in making the papers available for photographs. Caroline F.
