Leonhart Fuchs (1501-1566), sometimes spelled Leonhard Fuchs, was a German physician and one of the three founding fathers of botany, along with Otto Brunfels and Hieronymus Bock (also called Hieronymus Tragus). He saw the importance of practical experience as well and offered botanical field days for the students, where he demonstrated the medicinal plants in situ. He founded one of the first German botanical gardens.
