Initially, the... Wally didn't have a position in physics so everyone was associated with me and then finally we got him a faculty position. It was first an associate it was a tenure Professor, we called... it was called Biophysics, and then there was the question of getting space for him. And then we got space for him. So by about 1965 it took about four years of quiet lobbying because everyone said, well, you know, why do you need, Wally should go off and be independent some other place. But I think both of us felt I think the two of us together led to a much more effective place. I mean I could go to, you know, Cambridge for three months and it made no difference. Likewise he took a year off, was in Paris for a year and I talked to his students, and so it was very when we were away the lab didn't slow down at all. And then we recruited other very bright people to be with us so by... oh, by '66 we were probably, you know, our group was as productive as Sydney and Francis and the LMB.
