And so I knew that there were fellowships, and with a salary at the great level of $2300, I needed money if I were going to come and visit. So I got a fellowship at the Institute for Advanced Study. And what did my office consist of? A chair in the library with a drawer where I could keep my papers. But that was fine. And there was Hermann Weyl, the great man in mathematical physics, who give beautiful lectures that I could attend. And my friends in the physics department of the university knew I was interested in nuclear physics, so I found myself giving lectures in nuclear physics. And that led to an offer to come to Princeton. But Johns Hopkins at this time also wanted nuclear physics, and they offered me a position with a higher rank and a higher salary. But I felt that there were so many wonderful people in Princeton, it had such leadership in mathematical physics, that I should come here, and I did. That was the fall of 1938. I can remember my wife weeping as we left Chapel Hill in the car with our two children to come here, because we had so many happy memories of North Carolina, but we also had happy memories later, of Princeton.
