I tried to get a much closer cooperation with the biology department. There was, sort of… a fight going on between the two of us which at first was not too successful because it was the period when the molecular biologists tried to take over biology at Harvard… as a matter of fact did take over the biology at Harvard. And, for instance, eight positions that became vacated at that time in the biology department, seven were filled with molecular biologists, so that whole fields of biology were no longer represented in the biology department. I shall not give the whole history how this was changed, but at any rate, the students made a petition to the Dean and the President, to restore some biology and after the Dean had looked into the situation he divided the biology department into three parts: organismic evolutionary biology, cellular developmental biology, and molecular biology. And the most important regulation was that all replacements in any of the three could be voted on only by the members of the department. So, the molecular biologists could no longer take away any… any more positions in organismic biology. Now, when after this was done the cooperation with the biology department was… was almost perfect, in fact, people went back and forth as… as if it was one single institution.
