OUTLINE OF THE CAREER OF THOMAS BROOKE BENJAMIN Benjamin was born on 15 April 1929 in Wallasey, Merseyside, and educated at Wallasey Grammar School. He studied electrical engineering at Liverpool University 1947-1950, before moving to Yale University on a Rotary Foundation Fellowship to take an M.Eng. Benjamin then went to Cambridge University where he took his doctorate on cavitation in fluids. He was elected Fellow of King’s College, Cambridge in 1955, and appointed Assistant Director of Research 1958-1967 and Reader in Hydrodynamics 1967-1970, working in the Department of Applied Mathematics and Theoretical Physics, Cambridge University, on problems of fluid dynamics such as thin films, wave instability, drag reduction, and vortex breakdown. He was elected Fellow of the Royal Society in 1966, at the early age of 36. the Fluid Mechanics Research Institute, to promote interaction between mathematicians and experimentalists in advanced fluid mechanics. In 1979 he accepted appointment to the Sedleian Chair of Natural Philosophy at Oxford, which carried with it Fellowship of The Queen’s College. In addition to his contributions to the study of fluid dynamics, Benjamin retained a lifelong interest in music, as executant (piano and strings), conductor and composer. Somewhat later in life, he also In 1970 Benjamin moved as Professor of Mathematics to the University of Essex, where he set up Apart from periods as visiting professor at overseas universities, principally in America, Benjamin the marriage was dissolved in 1974. In 1978 he married Natalia Court, by whom he had a daughter. Benjamin was twice married: in 1956 to Helen Ginsburg, by whom he had a son and two daughters; remained in Oxford until his death on 16 August 1995. tumed to the composition of poetry. T. B. Benjamin NCUACS 63/1/97 DESCRIPTION OF THE COLLECTION The material is presented as shown in the List of Contents. Additional explanatory notes, information and cross-references are appended where appropriate to the separate sections and the individual entries. The surviving documentation of many aspects of Benjamin's career, is unfortunately sparse; several of his career moves seem to have resulted in the loss or destruction of papers. Section A, Biographical, provides a useful outline of the principal events of Benjamin’s life including his appointment to the Sedleian Professorship at Oxford. His non-professional interests, music and poetry, are well recorded, with examples of Benjamin’s own scores and writings on music, and poems, almost all wrtten in 1980. Section B, Notes, drafts and calculations, is the largest in the collection. It includes material relating to university courses taught by Benjamin and a considerable quantity of notes and other material relating to research, publications and lectures, much of it undated and difficult to assign as to category. higher education, especially the National Conference of University Professors of which he was a founder and first Chairman. Section F, Correspondence, is slight. a lecturer can be seen. It covers the years 1970-1994. Section D, Societies and organisations, is slight and does not convey the full involvement of Benjamin in the life of professional mathematical societies, or of his contribution to the publication of learned journals (he was a founder editor of the influential Journal of Fluid Mechanics). Section C, Lectures, conferences and visits, is far from being a complete record of Benjamin’s travel Section E, Mathematics and higher education, records Benjamin's concem with various aspects of and conference commitments, although something of the extent of his travels and his reputation as There is also an index of correspondents.

Benjamin NCUACS 63/1/97 Biographical player, orchestral Benjamin was involved with music throughout his life. As an undergraduate at Liverpool he played a major part in the university’s Music Society as violin manager and chairman, and as a composer. He wrote light-hearted music for reviews, pantomimes and performances by ‘Pantopera’, and more serious works which were regularly performed and attracted favourable critical comment. The university string orchestra, which he founded, performed widely in Liverpool and outside. choir-master, conductor and Michael At this time, when musical talent at Liverpool was unusually strong - John Shirley-Quirk, were among contemporaries - Benjamin was almost drawn to a full-time career in music. Having decided in favour of science, he kept music firmly in second place at Cambridge, but at Essex he again played an important part in the orchestral and choral concerts of the University Music Society.

He was active in writing for its Policy Documents, and in contributing more generally in articles and letters to the press to the discussion of current issues in educational policy such as selection, curriculum content, quality control and appraisal. Some of these appear at E.15-E.18. E.1-E.14 NATIONAL CONFERENCE OF UNIVERSITY PROFESSORS (NCUP) E.15-E.18 ARTICLES AND WRITINGS T. B. Benjamin NCUACS 63/1/97 Mathematics and higher education NATIONAL CONFERENCE OF UNIVERSITY PROFESSORS (NCUP) The NCUP was founded in 1989. A preliminary meeting was held in March and at a more formal meeting at Manchester in December officers were elected and a constitution approved. Benjamin was the first Chairman, serving until 1992, and subsequently as a member of Council. The NCUP was set up as a non-political independent organisation. Its aims, as set out in its brochures were: to support university professors in carrying out their responsibilities for the maintenance of academic standards; to provide a forum for discussion and a corporate voice on matters of concern to the nation’s university system; to improve public perceptions about the work of universities; to act as a means of collecting and disseminating information relevant to universities. The Conference held an Annual Assembly, commissioned policy documents for general circulated newsletters and information to its members. specific issues of concem and publication on involved Benjamin was closely or contributed to, the policy documents, made representations to ministers, conducted correspondence and wrote articles and letters to the press as NCUP Chairman.
