I already mentioned a lot of time, Heini Hediger. I just mentioned Bill Conway. Of course, in some ways, Bernhardt Grzimek made some impression on me, George Rapp as well. But for the daily work, probably the biggest influence has had Gunter Noge. We have had similar zoos. We became director, no, he became director about five years before I became director, but retired almost the same year. And we especially have had the same philosophy of zoo biology. And we became very close personal friends as well.
