If Bernal had... by the way, did you get a chance to look at the biography of JD Bernal? I had the book. It's really wonderful. I met Andrew Brown in Dublin and he's a wonderful guy. But, if Bernal hadn't been so pro-Stalin, he would have probably won a Nobel Prize, I'm pretty sure of that. Do you know that Churchill, he was an advisor to Churchill? And Churchill knew he was a communist, it's an incredible thing. I guess it's how people felt about Oppenheimer, you know. General Groves was not stupid, he said I don't care if he's a communist or not, he's a great physicist. That's the way it was, I guess. I suppose that Einstein was probably accused of being, if not a communist, a Marxist, I don't know. And, as I mentioned, Bernal was also a Sephardic name. So, I tried to find out if Derek [Price] had ever had any personal contact with Bernal and it turns out he was not, he didn't get his, he went to the University of London, but he didn't get his degree under Bernal. He just may have known about him. He knew about him. But, he didn't actually have any dealings with him when he was younger. I don't know when he first encountered the Social Function of Science but I encountered it early on because my uncle had given me a copy of that book and then when I went to the University of Colorado when we were talking about science and the war and everything, like that, Bernal's name came up. People knew about him then but only from that book because nobody was hearing about him during the war, he was working probably secretly. I don't know how open he was during the time of war, I guess he was just too busy.
