McGeorge "Mac" Bundy (March 30, 1919 – September 16, 1996) was an American academic who served as the U.S. National Security Advisor to Presidents John F. Kennedy and Lyndon B. Johnson from 1961 through 1966. He is primarily remembered as one of the chief architects of the United States' escalation of the Vietnam War. He was president of the Ford Foundation from 1966 through 1979.
After World War II, during which Bundy served as an intelligence officer, he was selected in 1949 to work for the Council on Foreign Relations. He worked with a study team on the implementation of the Marshall Plan. He was appointed a professor of government at Harvard University, and, in 1953, became its youngest dean for the Faculty of Arts and Sciences, working to develop Harvard as a merit-based university. In 1979, he returned to academia as professor of history at New York University, and later as scholar in residence at the Carnegie Corporation.
