Dean Gooderham Acheson (April 11, 1893 October 12, 1971) was United States Secretary of State under President Harry S. Truman. It has often been said that Acheson was more responsible for the Truman Doctrine than Harry Truman and the Marshall Plan than George Marshall. Although he developed anti-Communist views early in his political career, Acheson was a prominent defender of State Department employees accused during Senator Joseph McCarthy's anti-Communist investigations. Acheson persuaded Truman to dispatch aid to French forces in Indochina, but later counseled President Lyndon B. Johnson to negotiate for peace with North Vietnam. During the Cuban Missile Crisis, President John F. Kennedy called upon Acheson for advice, bringing him into Kennedy's ExCom.
