He fled the U.S. in the 1950s in danger of reprisals for his left-wing activities at Harvard and in Buffalo, New York. He landed in the former German Democratic Republic (Socialist East Germany), studied journalism, founded a Paul Robeson Archive and became a freelance journalist and author. One of his books is available in English: "Crossing the River. A Memoir of the American Left, the Cold War, and Life in East Germany" (2003, University of Massachusetts Press).]
