Dieter Gerhardt

Dieter Felix Gerhardt (born 1 November 1935) is a former commodore in the South African Navy and commander of the strategic Simon's Town naval dockyard.

Gerhardt was born on 1 November 1935, in Berlin, Nazi Germany.

Gerhardt joined the South African Navy after his father successfully persuaded naval chief Hugo Biermann to take the troubled teenager under his wing to try to instill discipline in him; he graduated from the Naval Academy in Saldanha Bay in 1956, winning the Sword of Honour.

It was also during this time that he met his first wife, British-born Janet Coggin, whom he married in 1958.

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.

In 1962, he attended a Royal Navy mine school in Portsmouth and completed the parachute training course at RAF Abingdon.

After his training in Britain, he was seconded to the Royal Navy.

He started his spying career in his late twenties, while still a junior naval officer, by offering his services to the South African Communist Party.

Bram Fischer referred him to the Soviet embassy in London, where the "walk-in" was recruited into the GRU, the Soviet military intelligence branch, and instructed to continue his career in the South African military.

As part of his service in the Royal Navy, he trained at HMS Collingwood (establishment) and served on HMS Tenby (F65), 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.

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.

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.

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.

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.

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.

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 spy for the Soviets for a period of twenty years in South Africa together with his second wife, Ruth, who had acted as his courier.

Gerhardt's cover was finally blown by Soviet double agent Vladimir Vetrov (given the codename "Farewell" by France's DST intelligence service) He was arrested at his hotel in New York City in January 1983 in a sting operation by the Federal Bureau of Investigation while he was taking a degree in mathematics at Syracuse University.

The CIA interrogated him for 11 days, during which time he gave up one of his Soviet handlers, Vitaly Shlykov (codename "Bob").

Shlykov, who did not know that the Gerhardts had been arrested, was also arrested on 25 January when he travelled to Zürich under the alias "Mikhail Nikolayev" for a pre-arranged meeting with Ruth Gerhardt.

He had in his possession $100,000 in cash that he intended to pay her; he did not disclose his real identity to Swiss authorities, and was sentenced to three years imprisonment for spying.

The then Prime Minister of South Africa P.W. Botha announced Gerhardt's arrest to the world in a special press conference on 26 January 1983.

Following his deportation to South Africa, Gerhardt and his wife were tried in camera in the Cape Town Supreme Court, with the prospect of a death sentence being handed down for high treason.

Both were released prior to the change of government following the 1994 general election.

She subsequently published a book in 1999 about her experiences called The Spy's Wife.
