Career
He served there from December 1952 to December 1958. Thompson was in contact with the Soviet intelligence after he returned to the United States of America. On 7 June 1963 Federal Bureau of Investigation surveillance watched a personal meeting with a known Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) officer and an individual who later was identified as Thompson. Thompson was arrested on 7 January 1965 at his service station in Babylon, New York where Thompson was running a home fuel-oil delivery service as a truck driver.
He pled guilty and received a 30-year sentence which he served in the Lewisburg Federal Penitentiary in Pennsylvania.
Thompson"s release came in 1978 in a three-way spy swap. As part of the deal, an American student Alan van Norman who was arrested on 2 August 1977 in East Germany for trying to help a family escape East Germany and an Israeli pilot imprisoned by the Marxist regime in Mozambique were released.
The swap arranged by East German lawyer Wolfgang Vogel. The triple prisoner play was the result of several months of negotiations.
Among the key Western officials involved in the bargaining was Congressman Benjamin Gilman, a New York Republican who has involved in obtaining freedom for a number of people imprisoned by Communist regimes.
United States. investigators held that Thompson was a Detroit-born American. Robert Glenn Thompson was born on January 1st in 1935 in Detroit, Michigan. His mother Berenice M. Simmers got divorced and moved to Tucson, Arizona where she died in March 1993.
He wrote that Thompson was born in Germany to a Russian mother and a German father, served in the Red Army as a tank commander and was trained to spy by the Komitet Gosudarstvennoy Bezopasnosti (Committee for State Security) and sent to Canada in 1949.
Thompson himself claimed when he was released in 1978 that he was an East German who was born in Leipzig and that spying "was his job." He said that he was a Soviet agent and Thompson was his cover name. In 2010 Nigel West said that Thompson"s claims to be a Soviet intelligence officer were false and that evidently Thompson believed that he would not be exchanged in a spy-swap if he acknowledged being a United States citizen.
