The post-docs worked on their problems, and the graduate students, you know, initially, would come what interested Wally and I. And their judgment wasn’t as good as ours. Except for Benno Müller-Hill who had the isolation, the dream of isolating the lactose repressor, and approached me coming to Harvard and I said, the perfect place, because Wally Gilbert also wants to get the lactose repressor, and they worked together. So, he was, I think, our only successful, only post-doc who went on to, you know, a good career by himself. So, it was at Cold Spring Harbor later, we didn’t have graduate students, and we had post-docs, but because, when they came to Cold Spring Harbor they had to work on small DNA tumor viruses, which was what I said that the lab was about. They couldn’t fail if they were intelligent, so they were working on the good problem where the Bob Tjian became the head of Howard Hughes, and Phil Sharp, and these people in the beginning all became important professors. But by the same judgment they said they wanted to come in and work on, but once they got to Cold Spring Harbor we didn’t tell them what to work on, but you know, they came to work in a certain area, so good people, you just give them space and freedom. And, you know, money.
