In January 1946, having closed down the Office of Strategic Services, America’s wartime intelligence arm, President Harry Truman threw a jolly lunch party at the White House for its successor. The new National Intelligence Authority comprised the secretaries of state, war and the Navy, with Admiral Sidney Souers as the new Director of Central Intelligence. Truman gave each of his guests a black cloak and a black hat, and then solemnly presented them with a wooden dagger.
Then the President advanced upon Admiral Souers and, like a magician pulling a rabbit from a hat, produced a large fake black moustache and stuck it on the new spymaster’s upper lip. ‘The new Director of Centralised Snooping,’ Truman announced.
