Aleksandr Korotkov

Aleksandr Mikhaylovich Korotkov was a Soviet intelligence officer and operative with the rank of major general. He became chief of foreign reconnaissance in the Soviet occupation zone in Germany in 1947 and chief of the KGB while he was stationed in East Germany in 1957. Korotkov was most notable as the intelligence officer who recruited Arvid Harnack in September 1940 and Harro Schulze-Boysen later in Berlin during the Nazi regime, effectively changing a resistance organisation who fought against Hitler into the espionage organisation known as the Red Orchestra. Korotkov was an associate of Ivan Serov.
