Air Vice Marshal Sir John Gerard Willsley Weston, (15 November 1908 – 13 June 1979) was a high-ranking signals officer in the Royal Air Force during the Second World War and the post-war years. He later served as the Deputy Head of the Secret Intelligence Service (MI6). There is a Weston Avenue in Leighton Buzzard that used to be housing for personnel at RAF Stanbridge. Since this was a signals establishment during the Second World War, it is believed that it is named after him.
