Well, there is of course, a very famous four tasks zoos have. Many people think that Heini Hediger explained these tasks. It’s not true. Heini Hediger always said, no, it was Bronx Zoo that said the four tasks of a modern zoo are recreation, education, research, and conservation. And I think even nowadays, all four tasks are important. I personally pursued mainly the conservation work but this doesn’t mean that I think education is less important. It was just not the field in which I was very much involved in. But Frankfurt has the longest history of zoo educators in Europe.
