Augustin Friedrich Walther

Augustin Friedrich Walther (26 October 1688 – 12 October 1746) was a German anatomist, botanist and physician who was a native of Wittenberg. He was the son of theologian Michael Walther the Younger (1638–1692).

In 1712 he earned his degree of philosophy from the University of Wittenberg, and in the following year received his medical doctorate from the University of Leipzig. At Leipzig he became a professor of anatomy (1728), pathology (1732) and therapy (1737). In 1730 he became director of the Leipzig Botanical Gardens, and in 1737 was rector at the university.

Among his numerous writings was a 1735 botanical treatise called ''Designatio plantarum quas hortus AF Waltheri complectitur'', in which he provides descriptions of thousands of plant species from his private botanical garden. As a physician he made contributions in the fields of myology and angiology, and has several medical and anatomical terms named after him, including: * "Walther's dilator": An instrument used for dilation of the female urethra. * "Walther's ducts": Also known as minor sublingual ducts. * "Walther's ganglion": Also known as the coccygeal ganglion. * "Walther's plexus": Also known as the intracavernous plexus; which is the portion of the internal carotid plexus in the cavernous sinus.

The plant genus ''Waltheria'' from the family Sterculiaceae is named after him.
