Then there were strong solid state physics on the other side, beginning under Lloyd Smith who had brought me to Cornell, and then under different directors following. The two labs separated but they both were part of the physics department, and the two lab directors wouldn't always see eye to eye and there was a group of three, a steering committee of three people with me as a chairman. And there was a theoretical group being very strong under... immediately after the war with Feynman, then Feynman unfortunately left us because he had too many graduate students, the graduate students took away all his time. And so Bacher who in the meantime had become the Chairman of the Physics Department at Cal Tech, lured him away from here promising him that he would have only as many graduate students as he wanted to have, and lured him to California. Well, we got Dyson for a while in his stead, but unfortunately Dyson also got lured away. Oppenheimer who initially didn't think that Dyson was very good, was now convinced that Dyson was a great physicist and so after a very short time at Cornell, Dyson left and went to the Institute of Advanced Study. We managed to keep a good group in theoretical physics at Cornell, but the... the two real stars, Feynman and Dyson, left because they were lured away to more attractive places.
