1,950 pages of files copied from FBI Headquarters in Washington, D.C., covering Nathan Gregory Silvermaster Group. Files contain approximately 1,400 narrative pages. Nathan Silvermaster was a leader of a Soviet espionage ring. Silvermaster was Chief of the division of economic analysis of the War Assets Board. This espionage investigation from 1945 to 1959 uncovered Soviet placed agents working within the U.S. Government. The case, titled Gregory, using the middle name of Silvermaster, exposed 27 individuals in the Silvermaster ring who gathered information from at least six Federal government agencies to turn over to the Soviets. No indictments for espionage were returned against any subjects in the Gregory case by any Grand Jury; however, a Grand Jury did return an indictment against Alger Hiss for perjury.
