Tennent Harrington Bagley (November 11, 1925 – February 20, 2014) was a high-level CIA counterintelligence officer who worked against the KGB during the Cold War. He is best known for having been the case officer and principal interrogator of controversial KGB defector Yuri Nosenko who claimed a couple of months after the assassination of President John F. Kennedy that the KGB had nothing to do with the accused assassin, Lee Harvey Oswald, during the two-and-one-half years Oswald lived in the USSR.
Bagley initially believed Nosenko was a true defector after meeting with him five times in Geneva, Switzerland, in May and June 1962, but, while reading the file of an earlier defector at CIA headquarters about a week later, he became convinced that Nosenko had been dispatched to the CIA to discredit what that earlier defector, Anatoliy Golitsyn, was telling the agency.[1][2][3][4]
