Since its foundation, the park has been controlled by De Koninklijke Maatschappij voor Dierkunde van Antwerpen, a society originally called Société Royale de Zoologie d'Anvers (The Antwerp Royal Society for Zoology). This also became the popular nickname for the zoo, "De Zoologie". The initial objective was to encourage zoological and botanical sciences. Its first director was renowned zoologist and botanist Jacques Kets (10 November 1785 – 1 February 1865). He accepted this position on one condition: a museum had to be built to house his nature-historical collections. This building was inaugurated in 1844 by H.M. King Leopold I. The predicate "Royal" was added to the name of the society on that occasion.
