So as a scientific assistant, you were working on your PhD. Yes, mainly. And Heini Hediger, he hold in winter a lecture at the university and in summer he usually had to repeat the lecture twice because there were over 150 students attending his lectures at the zoo. And here I, of course, had to prepare the lecture for Heini because he demonstrated animal behavior and so on and showed special specimens. So these were my task as scientific assistant of the university. And we’ve been talking now about Heini Hediger, who you worked for. You had mentioned, at one time, he was like a father to you.
