Abraham George Silverman graduated from Harvard was considered a brilliant mathematician and statistician who went to work in Washington D.C. in the early days of the President Franklin Roosevelt's New Deal in the Railroad Retirement Board. From there he found employment in the Federal Coordinator of Transport, the United States Tariff Commission and the Labor Advisory Board of the National Recovery Administration. During World War II, Silverman was civilian Chief of Analysis and Plans to the Assistant Chief of the Army Air Forces Air Staff for Material and Service, assigned to The Pentagon. Silverman supplied documents from the Pentagon to the Silvermaster group of Soviet spies. Silverman knew Greg Silvermaster to be a conduit for CPUSA chairman, Earl Browder.
In 1941, Silverman was on loan to the Treasury Department and worked for a period of time on the frozen funds policy. Assistant Secretary of the United States Treasury Harry Dexter White used Silverman to supply documents also for Soviet intelligence in the latter part of 1942 and early 1943. Presidential Assistant Lauchlin Currie furnished Silverman with oral information, including information that the United States was on the verge of breaking Soviet codes. Irving Kaplan of War Production Board also was giving information to be transmitted to the Soviet Union to Silverman. As the war progressed, the volume of material increased. Silverman worked closely with Lud Ullman, who also worked at the Pentagon and did the photographing of the stolen documents prior to being turned over to the Golos network.
In August 1945 Silverman left the Pentagon to work for the French Supply Council in Washington D.C., an office of the new French regime.
Silverman and Greg Silvermaster learned much about U.S. policies and about Lauchlin Currie and Harry Dexter White's own views through their association. Currie appears to have been involved in carrying out orders from Roosevelt to get U.S. intelligence services to return Soviet cryptographic documents to the Soviet Union and to cease decoding operations.
"Aileron" occurred in the Venona project and was identified as Abraham George Silverman. The “D.” first initial given here may be an error or perhaps based on Silverman generally being known as “George Silverman.” The first letter of the name “George” is rendered in Russian by a Cyrillic letter that is usually Latinized as “Dzh.”
Aileron as a cover name was an obvious reference to Silverman’s Air Force position.
