I mentioned that Terry Maple in an ’80s Director of Atlanta Zoo, he transformed Atlanta Zoo of one of the 10 worst zoos in the States to one of the 10 best zoos in the States. He was a great friend of Heini Hediger and he visited us very often in Zurich Zoo and so a friendship between Terry and me started. And we were always in correspondence with each other. And so the idea started to, start an exchange program for staff members between Atlanta and Zurich. And the intention was that my stay, as visiting scientist in Zoo Atlanta, was the start of this program. Unfortunately, I was the first but the last of the staff members that changed city. I was very generously welcomed in Zoo Atlanta and I got the opportunity to look into really every department of the zoo and of the friends of the zoo organization. So I think beside Heidelberg, that was one of my very important times to learn zoo biology.
