The details

Nathan Gregory Silvermaster (November 27, 1898 – October 7, 1964), an economist with the United States War Production Board (WPB) during World War II, was 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 penetration of the Federal government during the 1930s and 1940s, takes its name. His wife, Helen and stepson, Anatole Volkov, were members of his ring.
He was identified as a Soviet agent in the WPB operating under the code names Pel, Pal, “Paul” in the Venona decrypts; and as “Robert” both in Venona and independently by defecting Soviet intelligence courier Elizabeth Bentley.

Early years

Silvermaster was born of a Jewish family in Odessa, Russia (present-day Odessa, 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.


While nominally remaining on the employment rolls of the Farm Security Administration, Silvermaster arranged in 1942 to be detailed to the Board of Economic Warfare. The transfer, however, triggered objections from military counter-intelligence who suspected he was a hidden Communist and regarded him as a security risk. On July 16, 1942 the U.S. Civil Service Commission recommended "Cancel eligibilities ... and bar him for the duration of the National Emergency."


Silvermaster denied any Communist links and appealed to Under Secretary of War Robert Patterson to overrule the security officials. Both White House advisor Lauchlin Currie (identified in Venona as the Soviet agent operating under the cover name “Page”) and Assistant Secretary of the Treasury Harry Dexter White (identified in Venona as the Soviet agent operating under the cover names “Lawyer”; “Jurist”; “Richard”) intervened on his behalf. Silvermaster subsequently received two promotions and pay raises.

Kathryn S. Olmsted, the author of Red Spy Queen (2002), points out: "Every two weeks, Elizabeth would travel to Washington to pick up documents from the Silvermasters, collect their Party dues, and deliver Communist literature. Soon the flow of documents grew so large that Ullmann, an amateur photographer, set up a darkroom in their basement. Elizabeth usually collected at least two or three rolls of microfilmed secret documents, and one time received as many as forty. She would stuff all the film and documents into a knitting bag or other innocent feminine accessory, then take it back to New York on the train." Moscow complained that around half of the photographed documents received in the summer of 1944 were unreadable and suggested that Ullmann receive more training. However, Pavel Fitin, who was responsible for analyzing the material, described it as very important data.

War Production Board

At the War Production Board, Silvermaster was able to provide the Soviet Union with a large amount of data on arms, aircraft, and shipping production. In June 1943, Silvermaster sent a War Production Board report on arms production in the United States, including bombers, pursuit planes, tanks, propelled guns, howitzers, radar and submarines, sub chasers, and the like, to Soviet intelligence. Then, in December 1944, the New York MGB office cabled another Silvermaster report stating: "(Silvermaster) has sent us a 50-page Top Secret War Production Board report ... on arms production in the U.S."

Silvermaster was associated with Harry Dexter White at the Bretton Woods conference, and his testimony before the US Senate Internal Security Subcommittee covers "175 pages of interrogation and exhibits" regarding his espionage activities in the U.S.


He died on October 7, 1964, aged 65, possibly in Harvey Cedars, New Jersey.
