Unlike previous such meetings at which scientists had endlessly presented papers about their own work, Humboldt put together a very different programme. Rather than being talked at, he wanted the scientists to talk with each other. There were convivial meals and social outings such as concerts and excursions to the royal menagerie on the Pfaueninsel in Potsdam. Meetings were held among botanical, zoological and fossil collections as well as at the university and the botanical garden.
