What British intelligence officer worked as a double agent for the Soviet Union and was recruited by Arnold Deutsch?
Kim Philby Harold Adrian Russell "Kim" Philby (1 January 1912 – 11 May 1988) was a high-ranking member of British intelligence who worked as a double agent before defecting to the Soviet Union in 1963. He served as both an NKVD and KGB operative.
Elizabeth Bentley Elizabeth Terrill Bentley (January 1, 1908 – December 3, 1963) was an American spy for the Soviet Union from 1938 until 1945. In 1945 she defected from the Communist Party and Soviet intelligence and later (1952) became an informer for the U.S. She exposed two networks of spies, ultimately naming over 80 Americans who had engaged in espionage for the Soviets. When her testimony became public in 1948, it became a media sensation and had a major impact on Soviet espionage cases of the 1950s.
