Two wartime reports by the Allies attempted to analyse Hitler psychologically. A 1943 report by Walter C. Langer for the U.S. Office of Strategic Services (OSS) describes Hitler as having repressed homosexual tendencies and opined that he was an impotent coprophile. Psychologist Henry Murray wrote a separate psychoanalytical report for the OSS in 1943 that drew similar conclusions. Otto Strasser, one of Hitler's opponents in the Nazi Party, also told his post-war interrogators a similar story. British historian Ian Kershaw describes Strasser's statement as anti-Hitler propaganda.^[5]
