Powell (Supplement) CSAC 111/2/86 INTRODUCTION The material came to light at Powell's home in Bristol in February 1985 and was received by courtesy of Professor P.H. Fowler FRS of.the H.W. Wills Physics Laboratory, University of Bristol. PRESENTATION The 'new' 1985 material includes biographical records, correspondence, photographs and press-cuttings which were largely absent from the original collection received in 1973; there is in consequence almost no overlap or duplication of content or of archival class. For this reason, and in view of the considerable lapse of time, no attempt has been made to consolidate the two catalogues. The 1985 material has been treated essentially as a separate collection, presented and indexed as shown in the list of contents. DESCRIPTION pondence after his death. (A.101-A.106), with their endearing spontaneity. Powell's unassuming friendliness, so often invoked by others in letters of congratulation or condolence becomes visible, so to say, in many of the delightful photographs (A.107-A.142). Powell's research is represented chiefly by the contemporary records of the 1952 and The biographical material in Section A, though still not a full record, contains an interesting span of Powell's career from the meagre provision of the State Scholarship (A.4) to the worldwide renown of the Nobel Prize (A.6-A.32). The sad coincidence in 1969 of his retirement (June) and death (August) is also marked. Of-interest are the family letters Tantalisingly, a small proportion of the correspondence has now 1953 high altitude balloon flights in Sardinia (B.1-B.9). . The earlier research on cosmic associations, remains very scantily documented, only a few records of the Pugwash conferences rays, recorded in the notebooks of Powell and his team, is to be found in the 1973 collection. Powell's public life in national and international affairs, and service for many scientific surviving (Section D) what was thought to be the wholesale destruction of his papers and corres C.F. Powell (Supplement) CSAC 111/2/86 4 come to light and is preserved in Section E, though it can be no more than a tiny fraction of the original. References to the Memoir of Powell by F.C. Frank and D.H. Perkins (Biographical Memoirs of Fellows of the Royal Society, 17, 1971) are given in the form (Memoir, iy a) LOCATIONS OF FURTHER MATERIAL Mrs. Powell retains medals and citations of Powell's honours, family photographs (some going back to 1900), press-cuttings, Nobel Prize and other souvenirs.

Powell (Supplement) CSAC 111/2/86 SECTION B BALLOON FLIGHTS B.1 -B.18 Powell's discovery of the pion in 1947 led toa programme of balloon flights since ‘in order to obtain a reasonable number of events and investigate in detail the pion production process itself, it was essential to transport the [photographic J emulsions to the stratosphere, where they would be exposed to the primary cosmic ray protons! (Memoir, p.548). These flights, conducted at first in Britain, were moved in 1952 to the Mediterranean and involved collaboration with colleagues in many universities (Memoir, pp.550-51, 554). The surviving material includes interesting contemporary accounts of the 1952 and 1953 high altitude flights in Sardinia (B.1 - B.9) and correspondence on the manufacture of balloons by a Bristol company (B.12 - B.17). Photographs of the manufacture of the balloons, and of expeditions, are at A.123 -A.125, A.127, A.128. Correspondence on planning, funding and carrying out of balloon flights can be found in Section E, particularly in exchanges with Feather (E.15), Houtermans (E.18, E.19), Hutchinson (E.20), Massey (E.21), The Royal Society (E.26), Shapiro (E.31), S¥rensen (E.35), West (E.56), Yekutieli (E.69).

The surviving material, however, is unfortunately scanty and many of the conferences are unrepresented here. The material includes several of the addresses delivered by Powell at the conferences, printed matter, press-cuttings, and photographs including several taken at the first and second conferences in 1957 and 1958 (D.12, D.13).
