As early as 1923, Pfitzner and Hitler met. It was while the former was a hospital patient: Pfitzner had undergone a gall bladder operation when Anton Drexler, who knew both men well, arranged a visit. Hitler did most of the talking, but Pfitzner dared to contradict him regarding the homosexual and antisemitic thinker Otto Weininger, causing Hitler to leave in a huff. Later on, Hitler told Nazi cultural architect Alfred Rosenberg that he wanted "nothing further to do with this Jewish rabbi." Pfitzner, unaware of this comment, believed Hitler to be sympathetic to him.
