Leonard Albert Wiseman

Leonard Albert Wiseman OBE BSc ARI.C CText FTI (4 November 1915 – 20th January 2009), organic chemist, scientific intelligence analyst and scientific administrator. Following his early work as a research chemist and in intelligence, he became, successively Deputy Director of the Atomic Weapons Research Establishment, Director of the British Rayon Research Association, succeeding John Wilson, Deputy Director of the Cotton, Silk and Man-made Fibres Research Association when the BRRA merged with the British Cotton Industry Research Association (the Shirley Institute), becoming Director in 1969 until retiring in 1980 He also served for some years as Chairman of Council of the Textile Institute.

Wiseman was born in North London, and enjoyed cross-country running and other sports as a child. He won a scholarship from the Stationers’ Company School to study chemistry at University College, London. He graduated with first class honours in 1936. He married Winifred and had a son. (He lived to see four grandchildren and four great-grandchildren.)

Following graduation, he received a scholarship to conduct research on the chemistry of sucrose. He also started to study other problems in organic chemistry. The outbreak of war prevented the presentation of his Ph.D. thesis, and delayed publication of some of his work, which did finally appear in the Proceedings of the Royal Society, many years later. He became an Assistant Lecturer in Chemistry and a Fellow of Kings College, Cambridge. Near the end of the war, he was appointed to the British Intelligence Objectives Sub-Committee and was sent Germany where he worked at the Luftwaffe Research centre in Brunswick. he became fluent in German and met his second wife, Hansi.

He then came back to the UK, to work as Deputy Director of the Government Explosives Research Centre at Waltham Abbey. When the Atomic Weapons Research Establishment (AWRE) was created at Aldermaston, many of the Waltham Abbey staff played important roles in setting it up and developing its activities. Wiseman was among these and he was appointed Deputy Director in 1953, transferring to the Ministry of Supply in 1956 to oversee related production work. He directed and reported major studies of the physical chemistry of propellants and explosions - a logical continuation of his work at Waltham Abbey.
