This was rather in his early years, until the ’50s, early ’60s, but he retained good relationship with the circus. And I think that is one of the fields where time changed. In my mind, even as a student of Heini and admirer of Heini, in my mind, nowadays, it’s… Read More
I think Heini Hediger would be very proud how we proceed in Europe to have more natural enclosures for more natural groups of animals with self-sustaining breeding successes. I think he would be very satisfied. And less people knows the name of Heini Hediger, but I think more people follow… Read More
Even though they may not be familiar with his teachings, that they have somehow learned these principles through other professionals that they’ve worked with, even though they may not know who Heini Hediger is?… Read More
For example, with distances, I think nowadays every zoo biologist know what is an individual distance or what is a flight distance. We have to work with these distances in everyday zoo work. But probably less than 10% knows that these distances were discovered by Heini Hediger. And I think… Read More
But why do you think zoos in Europe have not embraced or younger generations have not embraced his teachings?… Read More
Unfortunately, there is hardly an official training for zoo biologists. Usually, zoo directors have the training of zoology and/or vet. But that’s usually not enough for zoo biology. So in Zurich, and later in Frankfurt, we offered short courses of one to two weeks for zoologists or vets, training in… Read More
What do you think Dr. Heidegger would say about the changes that are taking place in European zoos today?… Read More
Is this the case also in Europe or is it different?… Read More
Well, I think not more European remembers the name of Heini Hediger, and that’s, of course, a pity. And, therefore, I’m very glad that a long, long interview taken about 25 years ago with Heini Hediger will be published in these days. Which hopefully will remember younger colleagues who Heini… Read More
And in 1942, he wrote a book, (speaking in foreign language) It was translated into English only 14 years later, “Wild Animals in Captivity”. And this is the important start of scientific zoo biology. So this is probably his main achievement. And there, the main thing he proved is that… Read More
In the wild, keeping family of lions or whatever you consider have to consume food within the territory. So enough food has to grow or to be produced for prey animals, whereas in zoos, the animal keeper is bringing the food. And, therefore, the quantity of space can be much… Read More
What would you consider then to be his major contribution to the zoo world?… Read More
Is it his writings, his books?… Read More
Well, Heini Hediger has had more or less two professions. On one side, he was an animal psychologist and probably his main achievement in this field was the distances, the biological distances. As individual distance, social distance, flight distance, and so on, he discovered these biological facts, which are very… Read More
Well, it was very strange. A mutual colleague came and that was Terry Maple, who was a great fan of Heini Hediger. And in front of the restaurant, Heini told me, please call me Heini. He didn’t wait until we were in the restaurant and had a glass of red… Read More
Was it difficult for you to do that?… Read More
I think for me, it was not difficult to change from Professor Hediger to Heini. When- I felt very honored that he asked it and still feel honored by this. Read More
Is that a fair statement?… Read More
Well, I lost my father when I was 17 and I mentioned that Heini Hediger was my hero. And I remember exactly when he told me, please call me Heini and that was maybe a turning point for me. And it was really a relationship like a fatherly friend to… Read More
What were the circumstances when he said that to you?… Read More
