Leonhart Fuchs, German physician and botanist (born 1501)

Leonhart Fuchs, sometimes spelled Leonhard Fuchs and cited in Latin as Leonhartus Fuchsius, was a German physician and botanist. His chief notability is as the author of a large book about plants and their uses as medicines, a herbal, which was first published in 1542 in Latin. It has about 500 accurate and detailed drawings of plants, which were printed from woodcuts. The drawings are the book's most notable advance on its predecessors. Although drawings had been used in other herbal books, Fuchs's book proved and emphasized high-quality drawings as the most telling way to specify what a plant name stands for.
