Anatoliy Mikhaylovich Golitsyn CBE (August 25, 1926 – December 29, 2008)[1] was a Soviet KGB defector and author of two books about the long-term deception strategy of the KGB leadership. He was born in Piryatin, Ukrainian SSR. He provided "a wide range of intelligence to the CIA on the operations of most of the 'Lines' (departments) at the Helsinki and other residencies, as well as KGB methods of recruiting and running agents."[2] He was an Honorary Commander of the Order of the British Empire (CBE)[citation needed] and, as late as 1984, was an American citizen.[3]
Golitsyn worked in the strategic planning department of the KGB in the rank of Major. In 1961 under the name "Ivan Klimov" he was assigned to the Soviet embassy in Helsinki, Finland, as vice counsel and attache. He defected with his wife and daughter to the Central Intelligence Agency (CIA) via Helsinki on December 15, 1961
In 1964, Yuri Nosenko, a KGB officer working out of Geneva, Switzerland, insisted that he needed to defect to the United States, as his role as a double-agent had been discovered, prompting his recall to Moscow.[13] Nosenko was allowed to defect, although his credibility was immediately in question because the CIA was unable to verify a KGB recall order. Nosenko made two extremely controversial claims: that Golitsyn was not a double agent but rather a KGB plant; and that he had information on the assassination of President John F. Kennedy by way of the KGB's history with Lee Harvey Oswald in the time Oswald lived in the Soviet Union.[citation needed]
