Just getting back for a minute to this visit with him in the Cavendish—did you get to know Chadwick at all at the time?
No, I didn't get to know Chadwick. The only impression I had was from one meeting (and I think this was characteristic of him) in which he was rather taciturn and not very hospitable. You got the impression on first meeting Chadwick that he didn't have much time for you. I think this was just characteristic of the man. He was such a great physicist that it doesn't matter. I don’t know whether it was this time or another time in Cambridge. Yes, I do. It was not this time—it was later—that Karl Darrow and I happened to be in Cambridge at the same time, and we had a little interview with Rutherford. We heard later that Rutherford said to one of his colleagues: “You can't walk through the halls without running into Americans these days.”
