The Martin and Mitchell Defection occurred in September 1960 when two U.S. National Security Agency (NSA) cryptologists, William Hamilton Martin and Bernon F. Mitchell, defected to the Soviet Union. A secret 1963 NSA study said that "Beyond any doubt, no other event has had, or is likely to have in the future, a greater impact on the Agency's security program."
