Freedman NCUACS 137/2/05 5 GENERAL INTRODUCTION PROVENANCE The papers were received in July 2003 and July 2004 from Dr Freedmanand the Freedmanfamily. OUTLINE OF THE CAREER OF ALBERT FREEDMAN Albert Freedman was born on 26 July 1916 in London. He received part of his early education in Fontainebleau, France and Basel, Switzerland but returned to England in 1933 to enrol at Regent Street Polytechnic, London. After attending a course of evening classes, he graduated with a BScin Physics and Maths from London University in 1940 and was awarded a PhD for his work on echo formation in fluids by the sameinstitution in 1962. Between 1936 and 1938 Freedman worked in the research department of The Gramophone Company, nowElectric and Musical Industries (EMI), based in Hayes, Middlesex, on the development of fluorescent screens for cathode ray tubes. In 1940 he moved to Portsmouth to take up a position with the Naval Establishment as a research assistant on HMS Vernon where he contributed to work relating to searchlight technology used in the defence of naval convoys. The following year Freedman joined the Underwater Detection Establishment, which later became the Admiralty Underwater Weapons Establishment (AUWE), in Portland, Dorset. In 1966 he was appointed Principal Scientific Officer. He stayed with the organisation for over thirty-five years until his retirement. A fluent speaker of French and German, Freedman wassent, in 1945, as a navalintelligence officer to assess recently captured Nazi scientific research facilities in the Netherlands. Some of Freedman’s workonthis assignment remainsclassified. Freedman’s work at the AUWE was varied and involved both theory and application. His interests included the design of electro-magnetic equipment, shock and vibration protection, radiator fields, effects of baffles and layers, the measurement of echoes, and scattering and radiation processes. He was a pioneer in the use of computers for physics research and worked on the implementation of a number of specially developed early computer programmes. Freedman spent 1964/1965 as an exchangescientist with the Transducer Division at the US Navy Electronic Laboratory in San Diego, A. Freedman NCUACS 137/2/05 6 California, USA, where his research focussed on the problems associated with transducer array and signal processing. his retirement in After concentrating particularly on aspects of interaction of plates with incident acoustic fields. He was a 1977, Freedman continued his research work privately, theoretical Fellow ofthe Institute of Physics and the Institute of Acoustics. He served on the editorial board of the Journal of Sound and Vibration for seventeen years and regularly refereed papers submitted for publication in Acustica, the Journal of the Acoustical Society of America and Transactions of the Institute of Electrical and Electronics Engineers. DESCRIPTION OF THE COLLECTION The material is presented in the order given in the contentslist. It covers the period from ca 1929 to 2004. Section A, Biographical, contains a very small amount of material relating to various aspects of Freedman’s professional career. Section B, Research, is the largest section in the catalogue and constitutes a fairly comprehensive representation of Freedman’s scientific work. A series of titled folders containing a selection of research notes on a variety of topics, ranging from acoustic array investigations and bi-static scattering to lamb modesand transducer theory, documents Freedman’s professional and private research interests from 1949 to 1996. Some material relating to Freedman’s research workfor papers submitted to scientific journals appears in this section. Plots and computer printout relating to Freedman’s work during the 1980s on programmesfor acoustic modelling is also presented here. Section C, Publications, mainly comprises a chronological sequence of Freedman’s published scientific papers, 1948-1996. It contains working papers and drafts as well as a small amount of correspondence with publishers. Material relating to Freedman’s unfinished and unpublished booksis also presented here. Section D, Admiralty Underwater WeaponsEstablishment (AUWE), contains material from between 1944 and 1994 relating to Freedman's period of employment by the organisation. It comprises a series of formal AUWE reports authored by Freedman with associated working papers and drafts, a A. Freedman NCUACS 137/2/05 7 selection of lecture notes relating to courses attended at the South Dorset Technical College, Weymouth and a small amount of administrative correspondence. Section E, Visits and conferences, is composed of correspondence and papers relating to conferences and meetings attended by Freedman between 1956 and 1983. Freedmancontributed a talk or discussion paper to some of these conferences, most of which took place in the UK. The section also includes material concerning several events in the USA attended by Freedman during his time as an exchangescientist based in San Diego, California. Section F, Societies and organisations, contains a small amount of material relating to nine scientific and academic bodies, including the Council for National Academic Awards, the Acoustical Societyof America and the Leverhulme Trust, with which Freedman was connected. It includes correspondence and papers documenting research projects undertaken by Freedman in collaboration with the Department of Mathematics, University of Dundee. Section G, Correspondence, comprises material covering the period 1949 to 2001 and documents a range of work and research-related topics. It includes correspondence relating to proposed study visits within the UK and abroad and to Freedman’s collaborative work with staff at the University of Salford on the design and development of computer programmesfor acoustic modelling. There is also an index of correspondents. ACKNOWLEDGEMENTS Weare very grateful to the Freedman family, Dr Philippe Blondel and Dr Olga Gomezfor their assistance in making this material available. L.

Freedman NCUACS 137/2/05 10 Research SECTION B RESEARCH B.1-B.269 This section contains material relating to various aspects of Freedman’s research andscientific work. Some of the research undertaken by Freedman appears to have been directly related to his various publications in journals, although some is connected with lecture courses on maths and other subjects attended by Freedman at South Dorset Technical College, Weymouth. Freedman continued his research on acoustics and associated topics after his retirement in 1977. Material relating to this later work is also presented here. It includes plots, diagrams andprintout relating to his interest in and development of computer programmesfor theoretical acoustic modelling using different parameters. There was no obvious schemeof organisation to the material as it was received. Freedman appears to have worked in a meticulous but rather spontaneous way recording his ideas and thoughts on whatever paper was available at the time and rarely dating ortitling notes. Much of the research material presented in this section takes the form of raw data and ongoing project work rather than thoroughly collated and organisedfinal reports.

Freedman joined the Underwater Detection Establishment, which later became the Admiralty Underwater Weapons Establishment, in Portland, Dorset in 1940 and stayed until his retirement in 1977. During 1964/1965 Freedman worked as an exchange scientist at the US Navy Electronics Laboratory in San Diego, California, USA. He was appointed AUWE Principal Scientific Officer in 1966. His work included the design of electro- mechanical equipment, theoretical acoustic research, the development of shock and vibration protection and methods of echo and reverberation measurement. During the later part of his career Freedman wasalso involvedin setting up and directing several post-doctoral research fellowships at UK universities. The material presented here includes formal AUWE reports produced by Freedmanforinternal circulation, some of Freedman’s working papers, a variety of lecture notes and a small amount of AUWE-related correspondence.
