Before I accepted the job at Caltech I visited there in Christmas ’54 with Margaret, and then I went back by myself. She had to return to her job in Princeton, but then I went back. After we went to San Francisco she flew back to Princeton and I went back to Pasadena, and I gave a couple of seminars. One was on mesons and baryons, and mesons theory and so on; the other one however was on the K⁰¹, K⁰² idea which impressed Feynman enormously because he said he hadn't thought of it and he was just amazed and... and then I talked also about the renormalization group work, which he hadn't thought of either; and he didn't think there was anything in quantum electrodynamics that he hadn't thought of. So they offered me a job immediately. At that time it didn't take a year or so the way it does now with all the government regulations and so on. It took two days or so for them to have a faculty meeting and… and offer me a job, and later on that… that spring I… I accepted it. And when I went there in… starting in April–yeah, in April or early May ’55--it was taken for granted that… that Richard and I would work together. And we did. We did a lot of very amusing things; we discussed things, we had lot of fun together at that time. Later on I got sort of fed up with his self-absorption–what I considered his self-absorption and his ego and so on. But that time that hadn't happened yet and we worked quite happily together.
