Extract

The Chairman said that a short biographical note would illustrate the Lecturer's very wide experience Professor RICHARDS was engaged in research at the Royal Aircraft Establishment, Farnborough, and then went to the Bristol Aeroplane Co Ltd, from 1937 to 1939 He was a scientific officer at the National Physical Laboratory from 1939 to 1945 and then went to Vickers-Armstrong Ltd, where he was Assistant Chief Designer and Chief Aerodynamicist between 1945 and 1950 He became Professor of Aeronautical Engineering, University of Southampton, in 1950
