Allen Dulles

Allen Welsh Dulles was the first civilian Director of Central Intelligence (DCI), and its longest-serving director to date. As head of the Central Intelligence Agency (CIA) during the early Cold War, he oversaw the 1953 Iranian coup d'état, the 1954 Guatemalan coup d'état, the Lockheed U-2 aircraft program, the Project MKUltra mind control program, and the Bay of Pigs Invasion. He was fired by John F. Kennedy over the latter fiasco.

Dulles was one of the members of the Warren Commission investigating the assassination of John F. Kennedy. Between his stints of government service, Dulles was a corporate lawyer and partner at Sullivan & Cromwell.
