William Stephenson

Sir William Samuel Stephenson (23 January 1897 – 31 January 1989), born William Samuel Clouston Stanger, was a Canadian soldier, fighter pilot, businessman and spymaster who served as the senior representative of the British Security Coordination (BSC) for the western allies during World War II. He is best known by his wartime intelligence code name, Intrepid. Many people consider him to be one of the real-life inspirations for James Bond. Ian Fleming himself once wrote, "James Bond is a highly romanticised version of a true spy. The real thing is... William Stephenson."

As head of the BSC, Stephenson handed British scientific secrets over to Franklin D. Roosevelt and relayed American secrets back to Winston Churchill. In addition, Stephenson has been credited with changing American public opinion from an isolationist stance to a supportive tendency regarding the United States' entry into World War II.
