Deryabin, Petr Sergeevich

(1921–1992)

   One of the first important KGB defectors, Deryabin was a war hero who was wounded three times as a young officer in World War II. Recruited into the MGB, he first served in the Ninth (Guards) Directorate and then was posted to Vienna with the First Chief Directorate. In the early 1950s he defected to the Central Intelligence Agency, which safely exfiltrated him out of Austria. Deryabin later wrote a number of books on KGB operations.
