Papers and correspondence of Cecil Reginald Burch, 1901-1983.

Archive Collection

Scope and Content

The papers contain biographical and personal material, notably records of other members of Burch's family including his father, George James Burch, Professor of Physics at Reading University, 1882-1909, and his brother, Francis Parry Burch who worked with him at Metropolitan-Vickers. There is substantial research material relating to his university-based work in optics and mineral dressing and his late medical interests, especially vitamin B-group therapy and inositol. Almost all the surviving material from the Metropolitan-Vickers period relates to the work of Francis Parry Burch. There are conference talks and invitation lectures, 1932-1981 and some publications material. The surviving correspondence is not extensive though there is one relatively substantial sequence of letters on aspects of mineral dressing and mining.

Administrative / Biographical History

Burch was born in Oxford and educated at the Dragon School, Oxford, 1907-1914, and Oundle School, 1914-1919. He then entered Gonville and Caius College, Cambridge (with his elder brother Francis) to read for the Natural Sciences Tripos, 1919-1922. On graduating Burch and his brother joined the Research Department of the Metropolitan-Vickers Electrical Company, Trafford Park, Manchester where he spent eleven years until, after the distressing death of his brother in 1933, he felt compelled to leave Metropolitan-Vickers. He moved to the Physics Department, Imperial College, London, as a Leverhulme Fellow in Optics, 1933-1935 and then Bristol University where he spent the rest of his life, first as a Research Associate, then as a Fellow of the H.H. Wills Physics Laboratory and from 1948 to 1966 as Royal Society Warren Research Fellow. He continued to do research in the laboratory to within the last few weeks of his life.

Burch made important research contributions in industry and university to a number of very different fields. His main activities lay in the industrial development of induction heating applied to electric furnaces; in the evaporative distillation of organic substances, leading to a range of low vapour pressure oils and greases, and its application to the pharmaceutical industry; and in the construction of vacuum pumps and of thermionic power valves. In university research he worked principally in optics, especially in the figuring of aspheric surfaces to extremely high degrees of accuracy, leading to the production of reflecting microscopes of wide aperture, and then, while continuing to make valuable contributions to this subject, he gave his primary attention to mineral dressing, inventing new classifiers and separators. He was elected FRS in 1944 (Rumford Medal 1954).
