Well, it's true that, immediately before WWI, and for years after it, Hitler lived in Munich. But, much more than Munich, it was Vienna that shaped him. Read Brigitte Hamann's
Hitler's Vienna: A Dictator's Apprenticeship. Hitler really did resist becoming part of a proletarian crowd there. (Hamann has since gone on to Hitler's Munich and Third Reich years in
Winifred Wagner oder Hitlers Bayreuth, but that book has not been translated into English yet.)
Thanks for the background. I just stumbled across Hamann for the first time about an hour ago, when I did a google search of "Hitler" and "Vienna," checking out verginius' tip.
