context_page_description: Dieter Felix Gerhardt is a former commodore in the South African Navy and commander of the strategic Simon's Town naval dockyard. He was arrested by the FBI in New York City in 1983 following information obtained from a Soviet defector. He was convicted of high treason as a Soviet spy in South Africa together with his second wife, Ruth, who had acted as his courier. Both were released prior to the change of government following the 1994 general election.
context_section_description: As part of his service in the Royal Navy, he trained at HMS Collingwood and served on HMS Tenby, and passed classified information about the weapons systems there to the Soviets. Among the systems he compromised through these activities were the SeaCat and Sea Sparrow missiles. He was also responsible for passing the first intelligence information about the French Exocet missile to the Soviets. British journalist and security services specialist Chapman Pincher maintained that, while in London in the late 1960s, Gerhardt was able to interview Royal Navy Polaris submarine crews for potential candidates that the Soviets could approach. It was also during this time that he met his first wife, British-born Janet Coggin whom he married in 1958.
  Coggin says she became aware of her husband's Cold War spying activities eight years later in 1966, but chose not to turn him in, fearing that he would be executed, leaving her children fatherless. She says Gerhardt eventually gave her an ultimatum to become a spy too, which she declined, forcing the couple's separation. She divorced him in 1966 and moved to Ireland with her children, claiming that she lived in constant fear of the Soviet security services. She subsequently published a book in 1999 about her experiences called The Spy's Wife.
  In 1973 Gerhardt married his second wife, Ruth Johr, a Swiss citizen who author Chapman Pincher claims was already a spy for the German Democratic Republic. According to Gerhardt, he recruited her shortly after they were married. She travelled to Moscow to undergo training.
  Gerhardt rose through the ranks of the naval establishment as his career progressed. Upon his return from training in the United Kingdom in the early 1970s, he served as the naval liaison officer with the defence company that subsequently become Armscor.  From 1972–1978, he was appointed as a senior staff officer to the Chief of the SADF in Pretoria. In this position he was able to access South African Army and Air Force secrets and plans regarding the South African Border War. He claims direct involvement in aspects of Israeli and South Africa's military cooperation, using this position in 1975 to pass Israeli secrets to the Soviets, including details of the purchase of Jericho missiles from Israel.
  Later, he was appointed commander of the strategically important Simonstown naval dockyard.  In this position, he had access to all the South African Naval intelligence reports from the Silvermine listening post near Cape Town, as well as technical details of weapons systems. He reportedly revealed to the Soviets most of the Western naval surveillance techniques for the South Atlantic. During the 1982 Falklands War, Gerhardt was allegedly able to use his position to supply the Soviets with detailed information about the locations of Royal Navy ships in the south Atlantic that the South African Navy intercepted at Silvermine. Admiral of the Fleet Lord Hill-Norton publicly contradicted this view, but supported screening of Royal Navy officers who had been in contact with Gerhardt throughout his career.
  Gerhardt visited the USSR five times during his career, while his wife travelled with him twice in 1972 and 1976. He was reportedly paid 800,000 Swiss francs by the GRU for his spying activities; his contact in the GRU said that money was not the motive for Gerhardt.
