“In Jung: A Biography”, is mentioned that Jung was an Agent. He secretly worked for the Office of Strategic Services (OSS), which was the predecessor to the CIA. His first contact with the OSS was through his patient Mary Bancroft. The celebrated psychologist Carl  Gustav Jung cured Bancroft her asthma through analysis and became a lifelong friend.  The relationship of the exceptionally extroverted woman with Jung was summarized in her New York Times obituary: “To Jung … her appeal was textbook obvious”. In his scheme of things she was an extroverted intuitive like he was. The list of Bancroft’s male consorts over time included besides Dulles the film director Woody Allen, and Time magazine CEO Henry R. Luce.

Bancroft, in German and  good with people was recruited by Dulles to serve as an intelligence analyst for the United States Office of Strategic Services (OSS) from 1941 to 1945, while living and working in Zurich.Dulles was the OSS chief in Switzerland and later became the first Director of the CIA. It seems that Dulles’s had relationship with  Mary Anne Bancroft, which then also belonged to the circle of friends  of C.G. Jung. 

In 1941, during World War II, Jung’s job was to analyze the psychology of leaders. In return Jung became privy to top-secret Allied intelligence. It has come to light that C. G. Jung operated as “Agent 488” for and his handler, Allen W. Dulles, later remarked: “Nobody will probably ever know how much Prof Jung contributed to the allied cause during the war.” Jung became an important advisor of the US and sent ideas to Eisenhower, how the Germans could be persuaded psychologically of the uselessness of resistance against the allied forces. In 1945, General Dwight Eisenhower read Jung’s ideas for persuading the German public to accept defeat. Allan Dulles relied on Jung’s psycholgical advice, including Jung’s prediction that Hitler would kill himself. Such a characterization of Hitler, Stalin and Mussolini can be found in C.G. Jung speaking, Bollinger Press.
