For Werner de Lachenal (1736–1800), Swiss professor of botany and anatomy at the University of Basel from 1776, eminent for his knowledge of European plants. He obtained his PhD in 1763. He was a pupil of Haller, who was one of his main correspondents, providing him with details of flora and their location around Basel, the Jura mountains, Alsat and Bruntrutain. He was a friend of Linnaeus. He authored several monographs in Acta Helvetica. While at the university he substantially improved its botanical garden, the oldest in Switzerland, that had fallen into disrepair. He continually strived to obtain funds to reconstruct and develop the garden and to pay for its gardener. He opened the garden to the public to cover expenditures.
