Well, it was not me alone. It was already director in Frankfurt and we had a co-chairpersonship with Miranda Stevenson. And it was more or less that she did the work and I gave my name. And I think, yeah, it was at that time quite successful that we set Hamlins monkeys, for example, the main population is in Europe. So we concentrate in Europe on Hamlins monkeys and other species are in Australia or mainly North America. So we really said where which species should be bred. In 1980, you began lectures at the Veterinary Facility of Zurich, the University of Zurich.
