Allen Welsh Dulles (/ˈdʌlɪs/ DUL-iss; April 7, 1893 – January 29, 1969) was an American lawyer who was the first civilian director of central intelligence (DCI), and its longest serving director. As head of the Central Intelligence Agency (CIA) during the early Cold War, he oversaw numerous illegal activities, such as the 1953 Iranian coup d'état, the 1954 Guatemalan coup d'état, the Project MKUltra mind control program, and the Bay of Pigs Invasion in 1961. As a result of the failed invasion of Cuba, Dulles was fired by President John F. Kennedy.
Dulles was a member of the Warren Commission that investigated Kennedy's assassination. A conspiracy theory suggesting that Dulles and the CIA were somehow involved in Kennedy's assassination and its potential cover up in the Warren Commission have been subject to popular debate among historians, political commentators, and conspiracy theorists. In 1979, the House Select Committee on Assassinations (HSCA) concluded that the CIA was not involved in the assassination of Kennedy.[1]
