Soble spy ring

Since the late 1920s, the Soviet Union, through its GRU, OGPU and NKVD intelligence services, used Russian and foreign-born nationals as well as Communist, and people of American origin to perform espionage activities in the United States. These various espionage networks had contact with various U.S. government agencies, transmitting to Moscow information that would have been deemed confidential.

During the 1920s Soviet intelligence focused on military and industrial espionage in the United States, specifically in the aircraft and munitions industries, and penetrating the mainline federal government bureaucracies, such as the United States Department of State and War Department. These efforts had mixed results. A front organization was created by a NKVD agent in 1928 for the infiltration and placement of scientists into industry and government: the Federation of Architects, Engineers, Chemists, and Technicians (FAECT). "The FAECT never attracted enough followers to make an impact in labor conditions, but it served the progressive cause in other ways."

One chief aim was the infiltration, placement, and subversion of American political life at all levels of society. Earl Browder, General Secretary of the Communist Party of the United States (CPUSA), served as an agent recruiter himself on behalf of Soviet intelligence.

Browder later stated that "by the mid-thirties, the Party was not putting its principal emphasis on recruiting members." Left unstated was his intent to use party members for espionage work, where suitable. Browder advocated the use of a United Front involving other members of the left, both to strengthen advocacy of pro-Soviet policy and to enlarge the pool of potential recruits for espionage work. The illegal residency of NKVD in the US was established in 1934 by the former Berlin resident Boris Bazarov. In 1935, NKVD agent Iskhak Akhmerov entered the US with false identity papers to assist Bazarov in the collection of useful intelligence, and operated without interruption until 1939, when he left the US. Akhmerov's wife, an American who worked for Soviet intelligence, was Helen Lowry (Elza Akhmerova), the niece of CPUSA General Secretary Earl Browder. Recent information from Soviet archives have revealed that Browder's younger sister Marguerite worked until 1938 as an NKVD operative in Europe. She discontinued this work only when Browder himself requested her release from duty, fearful that her work would compromise his position as General Secretary.
