Johann Conrad Peyer (December 26, 1653 – February 29, 1712) was a Swiss anatomist who was a native of Schaffhausen. He studied medicine in Paris under Guichard Joseph Duverney (1648–1730), in Montpellier under Raymond Vieussens (1635–1713) and received his medical degree in 1681 at Basel. Later he returned to Schaffhausen to practice medicine. At Schaffhausen he performed research with Johann Jakob Wepfer (1620–1695), and Wepfer's son-in-law Johann Conrad Brunner (1653–1727).
in 1677 Peyer published Exercitatio anatomico-medica de glandulis intestinorum earumque usu et affectionibus, in which he describes the eponymous Peyer's patches. These anatomical structures are aggregated lymphatic nodules found in the lining of the small intestine. He was also the author of an important work on veterinary medicine titled Merycologia sive de Ruminantibus et Ruminatione Commentariae.
Famous quotes containing the words johann and/or conrad:
“The most passionate, consistent, extreme and implacable enemy of the Enlightenment and ... all forms of rationalism ... was Johann Georg Hamann. His influence, direct and indirect, upon the romantic revolt against universalism and scientific method ... was considerable and perhaps crucial.”
—Isaiah Berlin (b. 1909)
“His moving impulse is no flabby yearning to teach, to expound, to make simple; it is that “obscure inner necessity” of which Conrad tells us, the irresistible creative passion of a genuine artist, standing spell-bound before the impenetrable enigma that is life, enamoured by the strange beauty that plays over its sordidness, challenged to a wondering and half-terrified sort of representation of what passes understanding.”
—H.L. (Henry Lewis)
