The Analysis of Adolph Hitler, with Predictions of His Future Behavior and Suggestions for Dealing with Him, Now and After Germany’s Surrender, was a two-hundred and forty page typewritten manuscript prepared for the wartime OSS, (Office of Strategic Services), by the Harvard Psychology Department under the supervision of Henry A. Murray, MD. The report was commissioned by the head of the OSS, William, "Wild Bill" Donovan and was done in collaboration with psychoanalyst Walter C. Langer, Dr. Ernst Kris of the New School for Social Research, and Dr. Bertram D. Lewin of the New York Psychoanalytic Institute. The report used multiple sources in profiling Hitler, including informants such as Ernst Hanfstaengl, Hermann Rauschning, Princess Stephanie von Hohenlohe, Gregor Strasser, Friedelinde Wagner and Kurt Ludecke. The work is considered a groundbreaking study and was the pioneer of offender profiling and political psychology, today commonly used by governments when assessing international relations.
