Lionel Haworth. 4 August 1912 12 April 2000

Lionel Haworth was one of the leading aero engine designers in the world. After initial training in 1934 to 1936 with the Associated Equipment Company of Southall–the builders of London9s buses—he moved to Rolls–Royce, Derby, where he worked until 1963 when he transferred to the Bristol Siddeley engine company, which merged with Rolls–Royce in 1966. Throughout his career he was very much a 9hands on9 engineer who insisted in keeping close to work on any new engine for which he was responsible. He worked on Rolls–Royce engines for aircraft ranging from the Meteor to Concorde, his crowning achievement in Derby being the Dart engine, which was an extremely successful, admirably simple turboprop that powered the Vickers Viscount and 11 other aircraft and had a wide influence on the future of civil aviation around the world. In Bristol, as Chief Designer, he took overall responsibility for the Concorde, Harrier and Tornado as well as all other aero engines being developed and built by Rolls–Royce, Bristol, between 1963 and 1977.
