There is a small amount of biographical material relating to various aspects of Rotherham's career. It includes correspondence and papers concerning Rotherham's appointments at Brown-Firth, the UK Atomic Energy Authority (UKAEA) and the Central Electricity Generating Board (CEGB); his membership in professional societies and organisations; and documentation, in photographic form, relating to his career, 1957-1967. There are notebooks from his years as undergraduate and postgraduate student at University College, London; off-prints of his published papers, 1942-1967; and correspondence and papers relating to the British Fast Reactor Project, 1975-1976. There is a good record of lectures, speeches and talks given by Rotherham as Director of Research, UKAEA, Member for Research, CEGB, President of the Institution of Metallurgists and the President of the Institute of Metals. Conferences and meetings attended by Rotherham are documented, 1956-1969, including two Royal Society Discussion Meetings, on heavy section steel structures and advanced methods of energy conversion, which he organised and chaired in 1964 and 1965. Service on a number of advisory bodies is also documented, especially the University Grants Committee Technology Sub-Committee, ten years from 1961, and the Central Advisory Council for Science and Technology, 1968-1970. The surviving correspondence is not extensive but covers the period 1952-1990.
