I heard this fellow speak at "Facing History" in Brookline. He wrote and spoke on his book: "Hitler's Willing Executioners: Ordinary Germans and the Holocaust".
Great discussion on PBS by a brilliant young Harvard scholar, Daniel Goldhagen, of the Holocaust period and after. This is Part I. There are two more dialogues "More about Hitler's Willing Executioners and then Part II. Fascinating discussion with one of the most articulate scholars I have ever had the pleasure to hear.
