Yuri Nosenko

Yuri Ivanovich Nosenko (Russian: Юрий Иванович Носенко; October 30, 1927 – August 23, 2008) was a putative KGB officer who allegedly defected to the United States in 1964. Controversy arose over whether he was a genuine defector or a KGB "plant." As a result, he was detained by the CIA for over three years. Eventually, he was deemed a true defector. After his release, he became an American citizen and worked as a consultant and lecturer for the CIA.
