Friedrich Sigmund Merkel

Friedrich Sigmund Merkel was a leading German anatomist and histopathologist of the late 19th century. In 1875, he provided the first full description of Tastzellen which occur in the skin of all vertebrates. They were subsequently given the eponym "Merkel cells" in 1878 by Robert Bonnet (1851–1921).
