Allen Dulles, American lawyer and diplomat, 5th Director of Central Intelligence (d. 1969)
Allen Welsh Dulles (; April 7, 1893 – January 29, 1969) 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. His older brother, John Foster Dulles, was the Secretary of State during the Eisenhower Administration and is the namesake of Dulles International Airport.
