Nathan Gregory Silvermaster


Nathan Gregory Silvermaster was an economist with the United States War Production Board 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 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 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.

Career

Civil service

From August 1935 to November 1938, Silvermaster worked an economist in the Farm Security Administration. From November 1938 to July 1940, he worked on the Maritime Labor Board. From July 1940 to December 1944, he worked in the Department of Agriculture
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 and Assistant Secretary of the Treasury Harry Dexter White intervened on his behalf. Silvermaster subsequently received two promotions and pay raises.
From 1942 to 1945, he was also assigned to the United States Treasury. In mid-1945, he joined the Reconstruction Finance Corporation. In March 1946, he resigned from government.
On August 28, 1950, Lee Pressman said of Silvermaster, "I believe he was with the Maritime Labor Board when I was with the CIO, and in that connection I may have had some business dealings with him".

Espionage: Silvermaster Group

Kathryn S. Olmsted, the author of Red Spy Queen, points out: "Every two weeks, Elizabeth Bentley 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.
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: " has sent us a 50-page Top Secret War Production Board report... on arms production in the U.S."
In 1944, 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.
The Silvermaster spy ring operated primarily in the Department of the Treasury but also had contacts in the Army Air Forces and in the White House. Sixty-one of the Venona cables concern the activities of the Silvermaster spy ring. This represents 1% of the total and 3% of the translated/partially translated VENONA cables.
He died on October 7, 1964, aged 65, in Philadelphia.
