Blair Clark was a journalist and political activist who held many positions in both spheres.
While at Harvard University Clark befriended classmate John F. Kennedy. The two would remain in touch throughout Kennedy's political career, and Clark and Jacqueline Kennedy would correspond for decades. Other notable people with whom Clark was close include poet Robert Lowell and journalist Theodore H. White. Clark served as General Manager of CBS News from 1961-1964, and later held positions at the New York Post and The Nation. Politically, Clark was known as an avowed "left wing" Democrat. In 1968 he served as Sen. Eugene J. McCarthy's national campaign manager for the Democratic presidential nomination. Later Clark became treasurer of the New Democratic Coalition, a group of disaffected liberals from the 1968 election that tried unsuccessfully to foment a national movement. When the Watergate break-in occurred, Clark was serving as the Democratic National Committee's communications director.
