K. Vonnegut, "Slaughterhouse-five or The Chidren's Crusade"
"...Even then I was supposedly writing a book about Dresden. It wasn't a famous air raid back then in America. Not many Americans knew how much worse it had been than Hiroshima, for instance. I didn't know that, either. There hadn't been much publicity.
I happened to tell a University of Chicago professor at a cocktail party about the raid as I had seen it, about the book I would write. He was a member of a thing called The Committee on Social Thought. And he told me about the concentration camps, and about how the Germans had made soap and candles out of the fat of dead Jews and so on.
All I could say was, "I know, I know. I know."..."
I Love This Book.
