The French doctor Jean Bauhin (1511-1582) converted to the Reformed faith. In the course of the persecution of the Huguenots he fled to Basel in Switzerland. He founded the scholarly family Bauhin, which produced numerous scientists until the 18th century. His sons Caspar and Johann became famous doctors and botanists.
His son Caspar Bauhin (1560-1624) studied medicine at Basel University and botany at Tübingen University; his botanical abbreviation is "C.BAUHIN". From 1589 he was a lecturer and then first full professor of anatomy and botany at the University of Basel. He is regarded as one of the "fathers of botany" with regard to naming (nomenclature), individual descriptions (physiognomy) and arrangement according to habitual similarities (systematics). Caspar Bauhin was the first to completely differentiate between species and genus and described in his botanical works "Prodomus" and "Pinax theatri botanici" about 5,640 plant species known at that time. Among other things, he was also the first to describe the American vine species Vitis labrusca. With this he also influenced the classification of the vine system.
