Nathan Gregory Silvermaster
Russian-American spy (1898-1964)
Nathan Gregory Silvermaster (November 27, 1898 – October 7, 1964) was an economist with the United States War Production Board (WPB) during World War II, during which time he was also the head of a large ring of Communist spies in the U.S. government. It is from him that the FBI Silvermaster File, documenting the Bureau's investigation into Communist Party USA penetration of the U.S. federal government during the 1930s and 1940s, takes its name. His wife Helen and stepson Anatole Volkov were members of his ring.
Silvermaster was identified as a Soviet agent in the WPB operating under the code names Pel, Pal, and "Paul", in the Venona decrypts; and as "Robert" both in Venona, and independently by defecting Soviet intelligence courier Elizabeth Bentley.
Background
Silvermaster was born to a Jewish family in Odessa, Russia (present-day Odesa, Ukraine) in 1898. He moved with his family to China, where he learned to speak perfect English with a British accent. He emigrated to the United States and earned his B.A. from the University of Washington in Seattle (where he was "stated to be a known Communist") and a Ph.D. from the University of California, Berkeley, where his thesis was entitled Lenin's Economic Thought Prior to the October Revolution. He became a naturalized American citizen in 1926. He was reported to be in contact with a very large number of Communist Party USA officials, and was active in a number of Communist front groups.
