"

On the suggestion of his court-preacher, Johann Friedrich Wilhelm Jerusalem, in 1745 he founded the Collegium Carolinum, an institute of higher education which is today known as the Technical University of Brunswick. He also hired Gotthold Ephraim Lessing as the librarian for the Bibliotheca Augusta, the ducal library. Lorenz Heister of the University of Helmstedt named the botanical genus Brunsvigia in his honour, in recognition of his encouragement of botany and the study of B. orientalis.[1]
