Joseph von Gerlach
Joseph von Gerlach (April 3, 1820 – December 17, 1896) was a German professor of anatomy at the University of Erlangen. He was a native of Mainz, Rhineland-Palatinate. Gerlach was a pioneer of histological staining and anatomical micrography. In 1858 Gerlach introduced carmine mixed with gelatin as an histological stain. "Gerlach's valve" (valvula processus vermiformis) is named after him. This anatomical structure is a fold of membrane located at the opening of the vermiform appendix. (text from Wikipedia)
