PIPPARD Pippard was born in Yeovil in 1891 and educated at Yeovil School and Bristol University where he studied civil engineering. served for two years as an articled assistant in the Bristol office of consultant engineer A.P.1. Cotterell before obtaining a position as assistant engineer with the Pontypridd & Rhonda Valley Joint Water Board. Graduating from Bristol in 1911 he In 1915 he was appointed as technical adviser to the Director of the Air . y pa His is evidenced the R.100 and R.101 (see B.21). In 1933 Pippard moved to Imperial College where for more than twenty years where he contributed to the work of the structures section Department of the Admiralty in improving aircraft safety and, incidentally, advancing structural science. interest in aircraft structure continued after the war, first as a partner in a firm of aero~ nautical engineers, 1919-1922, and subsequently as Professor of Engineering at Cardiff, In this period he was particularly associated 1922-1928, and Bristol, 1928-1933. with the experimental testing of airship structures in connection with the building of he presided over one of the finest civil engineering departments in the country, winning His own active pursuit of researc! the respect and affection of staff and students alike. Although Pippard was the subject of some press criticism for the length of time his Thames Pollution Committee set up by the Minister of Local Government and Housing to make recommendations on the future management of the tidal reaches of the river. His early M.Sc. thesis dealt with masonry dams and in his last five years at dams. Imperial College he undertook research projects on arched dams. In the public domain, he served for ten years, 1951-1961, as Chairman of the by a growing number of with Letitia Chitty. od b f one be published papers, many written In coliaporation Throughout his career he retained an interest in the structure of blist lat an al tre .? a . a * 3 A.J.S. Pippard CSAC 97/1/84 Committee took to report, its work proved of immense benefit to those living and working in the capital. He also took part in an investigation for Hatfield Development Corpora- tion into the gale damage to houses which occurred in November 1957, and in 1968-1969 he served as a consultant for Westminster City Council on the safety of system-built tall blocks of flats in respect of the Lisson Green development. Over many years he was actively involved in the affairs of the Institution of Civil Engineers, serving as its president, 19 55~1959.: DESCRIPTION OF THE COLLECTION The collection is particularly strong in material of a biographical and personal nature. Of especial interest is the extensive autobiographical account written by Pippard towards ihe end of his life (A.4). virtually every aspect of his career (A.2, A.3), and two scrapbooks devoted to his year There are also two scrapbooks covering as president of the Institution of Civil Engineers (A.25, A.27). Almost all the material available relating to Pippard's scientific work is con- cerned with his research on aircraft structures which is represented by a series of committee report (B.37). of articles and broadcaster. It covers a period of nearly fifty years and a variety of tion and iraining of engineers. This last topic was of particular importance to him survives.
