I respected Bethe a lot. I liked him very much. I… he had some curious traits. He was very marked by German inflation because he lived through the post-First World War German inflation where you couldn't… you didn't know the price of anything. And then the mark was worth nothing and things were… it bothered him all his life. So he was very, very disturbed that he'd have to relive that again. So he was very, very careful with money. He was always hedging. He had a very elaborate stamp collection because he thought stamps would be a good hedge against inflation. And he would… if he came to New York on whatever business and he had breakfast in the hotel, he would give me the bill, which I would pay. I never said anything. It was very odd. I have, still saved, some of the bills. Two scrambled eggs and coffee and toast, $3.86. And fine, I paid him $3.86. You know, I understood what his feelings were.
