At the Institute, he kept pretty much to himself. He… I think he ate with us occasionally but he didn't say very much and kept pretty much to himself, and there was no reason… I didn't have anything to say to him, except, you know, 'I admire you very much' and so on and so forth and whatever, but then I'd been to New York or somewhere and I came back, and Dyson and I were on the same train and we found ourselves in the same odd… we were stuck in the same station outside of Princeton. And somehow, whether we had a car or took a taxi, or… anyway, we went back to his house. And we had some drinks. And we talked a lot. Now it turned out that he was in the process of getting a divorce.

So he was living by himself in this house and he was a little bit, I think, a little bit less… well, he was more open to this. So we talked and after that, we became pretty good friends. And of course we never worked together. I… we did work on the Orion together but I mean, I… I have nothing… I mean, I couldn't contribute anything to anything Dyson was doing. He is so fast and so incredibly smart.
