Whereas in Germany, the profession of zookeeper started with an official training just after World War II. It is a three-year training with a final examination. And it even is possible nowadays to do a further training as master keeper. So in Germany, it’s a long, long tradition of training in keepers. In Switzerland, nowadays we have more recognized zoos. And so that was still, when I was in Zurich, in the late ’80s or early ’90s, we started a training for keepers as well. You mentioned that you were a scientific assistant.
