I don’t think, in my case, there was one special person who made a large difference, but I think there were several people who made a considerable difference. For example, when I… in… the war when I went and worked in the Admiralty, I worked with group of people… headed by a man called Massey… Professor Harrie Massey. He seemed to be a very venerable figure to me because he was a full professor, as they say here, and… and he was a fellow of the Royal Society and so on. And I thought he was… it turned out he was 34, I think, at the time, I worked out afterwards, but I, sort of, thought of him as much older. And… it’s interesting that I don’t think I was aware specially of being influenced by him until I heard him give a talk, many years later, at a dinner of the Royal Society. And he gave a… instead of giving a sort of rather frivolous after dinner talk, he gave a quite interesting and serious one. To my astonishment he kept repeating a lot of my ideas. Well, I realised he hadn’t got the ideas from me, I got them from him, you see, but I hadn’t realised I got them from him until I heard him talk that way. So you can have a lot of influence of that sort. I knew I was influenced by him but I didn’t realise quite to what extent. And I was certainly influenced by [William Lawrence] Bragg, the… the younger Bragg, as a crystallographer, and also by Linus Pauling but that was a more indirect influence, not so much a… a personal one, but just following the way he… he did his work. So, there’re a number of influences of that sort but there wasn’t, I think, one person who made an enormous difference, there were several people who made a considerable difference.
