Few people know of the affair Adolf Hitler had with his niece, Geli Raubal. The couple shared a strangely intense, passionate relationship, but it was always dogged by Hitler's intolerance, his chauvinistic attitude to womanhood and his possessive jealousy.
In 1931, aged 23, Geli Raubal was found dead in the Munich flat she shared with Hitler, his revolver on the floor and an unfinished letter on the table. Hitler was shattered by his niece's death, and for the rest of his life couldn't speak...
What about Hitler's neice Geli?That was defintely one twisted relationship. Old onesy's incestuous partnering was clearly not the action of a well-balanced person, especially if it was excercised as mentioned on the page you linked. I pulled the following Hitler quote from one of the reviews. A psychoanalyst would have a field day with this one:
"I never feel tired when my storm troopers and soldiers march past me and I stand at this salute. I never move. My arm is like granite, rigid and unbending. But Goering can't stand it.... He is flabby. But I am hard."
