Born in 1939, he grew up in New York City and went on to study philosophy and western European history at Swarthmore College and Stanford University.
By the time he graduated, he was heavily involved in political activism, and worked first as a community organizer in Newark, and then as a reporter in Latin America.
After making The People’s War, a film on the guerrilla movement in Venezuela, he moved back to New York City and helped to found Newsreel, an underground media collective which produced some 60 documentaries and short films about radical political subjects and the anti-war movement. It was during this time that Kramer developed his highly distinctive cinematic style, a blending of fiction and documentary filmmaking.
In the early 1980's, Kramer relocated to France, where he remained a prolific filmmaker until his death in 1999.
