Fuchs came to the house several times while I was there, and he was always a welcome guest and he was very, very nice. I mean we all felt very fond of him. He was very gracious guest and he was a lonely fellow. He was at Harwell at that time running the theoretical division, and he liked to come to Birmingham and he and Peierls, of course, had been old colleagues. So they were very close, and he loved the Peierls children. He was very good with the children, altogether just a sort of a friendly uncle type of person. And so we enjoyed it when he came, and Genia liked him too, so he was one of our favourite guests. And then, of course, I don't remember exactly the date at which Fuchs was arrested, whether I was still in Birmingham or not. Yes, I mean it was in January... It was January, yes. So it happened while I was there. Anyway, that was a terrible shock of course, and suddenly it turned out he was not only just a spy, but the spy, I mean he was the number one spy, and for Peierls personally it was a terrible betrayal. I mean Peierls had been responsible for bringing him to Los Alamos in the first place so it meant that sort of England had become untrustworthy, not just Fuchs, and that was for Peierls a terrible blow, which I think in a way was more of a blow for him than the Oppenheimer affair was for Oppenheimer. I mean I always thought Oppenheimer never really - I don't think Oppenheimer really was suffering from the public disgrace as much as Peierls did. Anyhow, that's my impression. But it was certainly a disaster for Peierls in many ways. For both of them. And Genia took it very hard too. I mean Genia was absolutely vitriolic that a man could do that to his friends. She always said, 'In Russia we know how to suffer. We don't betray our friends.' Anyway, that was very hard. And Peierls went to visit Fuchs from time to time, but Genia absolutely refused to have anything to do with him.
