[About his father, Ludwig] Two Gestapo officials came and took him away. Then the thing after that was that my father had this big library. Partly it was because he was a collector of antiquarian books, but the bulk of it was his library. He also had an enormous number of review copies being the publisher, and so on. They came and took most of it. A removal van came with large cases, and people who knew what they were doing took the books and put them in there.
