Sir Anthony Blunt, British art historian and Surveyor of the Queen's Pictures, with a painting by Velazquez. He was later exposed as a former Soviet spy.
A venerable art historian who was director of the famed Courtauld Institute of Art and, for a spell, the man who presided over the Royal Family’s paintings, was for years a spy for the Soviets. Discovered, he made a secret confession to British authorities in 1964, snitching on a number of other British Soviet agents. In return, he had immunity, but his role was revealed by new British Prime Minister Margaret Thatcher in 1979 and he was forced to make a tearful confession on the BBC. He died of a heart attack three years later.
