The St. Louis Zoo was an interesting place, it was one of the very few circus zoos in existence. It didn’t call itself a circus zoo but it actually had animal acts. It had elephant shows, lion shows and chimpanzee shows. They were all done quite professionally, but almost all of them would now be considered quite improper. And one of the first jobs George George Vierheller gave me, was becoming an announcer for the chimpanzee show. So I learned an enormous amount about chimpanzee behavior and training.
