Gerald Holton would become a good friend. He and I were both disciples of Phillip Frank, Uncle Phillip as we called him. He said, 'I think there may be a job at the Harvard Cyclotron, because the guy who was the house theorist is leaving. There may be an opening there'. I said, 'Gee, that would be wonderful, well, what do you have to do?' He said, 'Well, you don't have to do anything, just do your work.' Okay.

So Gerry must have put in a good word for me, because I got that job, and that was the thing that completely transformed my life. I had two years there, in which I had no responsibility except my work. I just did what I wanted to do. I audited courses and I became very interested in the experiments that were being done at Stanford on electron scattering from targets. I became quite expert in that, wrote some papers on that. And so I'd written some papers, I'd given some little talks and stuff, and loved living in Cambridge. I was just… I had a great time in Cambridge. Then, of course, the two years was up. There was a question of what, then, to do.
