George Blake (born George Behar 11 November 1922), is a former British spy who worked as a double agent for the Soviet Union. He became a Communist and decided to work for the KGB while a prisoner during the Korean War. Discovered in 1961 and sentenced to 42 years in prison, he escaped from Wormwood Scrubs prison in 1966 and fled to the USSR. He was not one of the Cambridge spies, although he associated with fellow double agents Donald Maclean and Kim Philby after reaching the USSR.
