Biography
Maurice Hyman Halperin was a scholar, former State Department and Office of Strategic Services official, and Boston University professor. In 1953 the Senate Internal Security Subcommittee questioned him about allegations that he had supplied information to Soviet intelligence. Halperin denied the accusations, invoked the Fifth Amendment, lost his university position and moved to Mexico. With extradition a concern, he and his wife moved to the Soviet Union in December 1955, where he worked with the Soviet Academy of Sciences. He left for Cuba in 1962 and later settled in Canada. Later archival scholarship treated the espionage allegations as substantiated, but no U.S. criminal trial adjudicated them before his flight.
