In the spring of '32 I went again to Rome, still on the Rockefeller Fellowship. This time I was almost completely occupied by writing the Handbuch articles, but I had a very good time. There were two other visitors, George Placzek and Edward Teller. George Placzek in... sat to my left in the same room in which I was writing. He had a very... he also was supposed to write a Handbuch article about the Raman Effect, but he found it far more difficult to deal with that. And so mostly he turned the pages, but there was not much on it. But I developed a very nice friendship with Placzek who was one of the nicest and most thoroughgoing people I have known. He was indeed studying the Raman Effect of molecules and later on he was... he studied the behavior of neutrons diffusing through matter. Every time he was extremely thorough and went to the sources. Usually he loved the library at the institute in Rome because he could follow the subject of Light Scattering back to 1800's, and he then used that in his article. We went out to dinner together every day and remained friends ever since. There was also Edward Teller who mostly worked outside the institute, but also worked about molecules and I got to know him also well and we also became friends.
