OUTLINE OF THE CAREER OF PETER HOWARD FOWLER For an outline of Fowler’slife and career see NCUACScatalogue 115/1/03. DESCRIPTION OF THE COLLECTION This supplementary collection is presented in the order given in the list of contents. It covers the period from 1960 to 1988. It should be consulted in conjunction with the principal body of Fowler papers catalogued as NCUACS115/1/03. Section A, Biographical, is the smallest section and includes Fowler’s entries in professional registers such as Who’s Who and presscuttings relating to his research on cosmic rays. Section B, University of Bristol, includes correspondence, agendas, minutes and reportsrelating to University departmental committees. There is also material relating to teaching duties, examination and research supervision - including syllabuses, teaching timetables, student questionnaire results and analysis - and correspondence with prospective members of Fowler’s Cosmic Rays Study Group. Section C, Balloon flights, is arranged in chronological order and complements the earlier material catalogued in Fowler NCUACS 115/1/03. The bulk of the material relates to flights made between 1970 and 1975 launched from Palestine in Texas and Sioux Falls in South Dakota, USA. Thereis alsoa little material covering the transatlantic flights launched from Milo in Sicily. Documents include correspondence regarding balloon flight arrangements, project proposals, flight reports, copies of papersand lectures. P. H. Fowler NCUACS 129/2/04 6 Section D, Research, mainly covers Fowlers cosmic ray research using balloons, cosmic ray detectors such as BUGS4 and accelerator facilities including Nimrod and the University of Princeton Accelerator. The material comprises correspondence, proposals and grant applications, research outlines and reports. Other topics covered are the plastic track detector CR39 used to capture cosmic rays and the UK 6, Solar Flare and the Ariel 6 satellite programmes. There is a small sequence on Pi-mesonsin cancer treatment. Section E, Drafts and publications, is not extensive. It is arranged in chronological order from 1964 to 1979 and principally comprises drafts of Fowler’s scientific papers, figures, tables and correspondence. Section F, Lectures, principally relates to Fowler’s public lectures, all on the topic of cosmic rays with the exception of his 1971 Rutherford Memorial Lecture on Pi-mesons in cancer treatment. The material comprises drafts, notes and correspondence from 1962 to 1987. Thereisa little academic teaching material and an Honorary Degree oration at the University of Bristol. Section G, Visits and conferences, is one of the larger sections and complements previous material in NCUACS 115/1/03. It is arranged in chronological order from 1964 to 1987. Principal visits covered are a visit to the USSR in 1969, the Royal Society of New Zealand Rutherford Memorial Lecture Tour in 1971, a visit to the University of Chicago Enrico Fermi Institute in 1978 and International Union of Pure and Applied Physics International Cosmic Rays Conferences. Section H, Societies and organisations, forms the largest section of the collection and documents Fowler’s involvement with ten UK and international organisations. Bodies covered include the European Space Research Organisation (Fowler was a consultant, 1974-1977), Rolls-Royce plc (early consultancy work 1984-1987), the Royal Society (Fowler served on various British National Committees and there are documents relating to the administration and funding of his Research Professorship) and the Science Research Council (Fowler was involved with a number of committees mainly concerned with astronomy and grantallocation). Section J, Correspondence, is divided into two sequences: an alphabetical sequence arranged by correspondence, and references and recommendations. Dates covered are 1966 to 1987. Correspondents are mainly scientific colleagues and historians of science, although there are no extended exchanges. There is also an index of correspondents. P. H.
