I was reading the following article on the BBC's website about Hitler's personality
and a few things caught my eye. His avoidance of small talk, his annoying voice, his general social inadequacy. Normally when people mention these things about the famous dead, they are quick to follow up that the person must have had Asperger's Syndrome (AS). I didn't read that in this article though, and now I come to think of it I've never seen Hitler's name on any of those internet lists about all the great people who "must have had" AS. After all, it's such a gift, such a wonderful thing that makes you an exemplary human being...right? ;)
Hitler does feature on the Wikipedia article about famous people posthumously diagnosed, but I see he has a special note that indicates people disagree and think there isn't enough evidence for a diagnosis. Yet we know more about him than many other distance historical figures as he has only just passed from living memory.
