Jean-Nicolas Marjolin (1780-1850): An ulcer, an anthrax, and a rose
1Department of Anatomy, University of Quebec at Trois-Rivieres, Trois-Rivieres, Canada.
Abstract:
Jean-Nicolas Marjolin was a 19th century French anatomist and surgeon. Although not strictly speaking a pivotal figure in history of medicine, he deserves to be known for at least three reasons. He (more or less accurately) described a type of ulcer which is nowadays referred to as Marjolin's ulcer (1828); he had the privilege of operating on the world-famous Charles-Maurice de Talleyrand-Périgord for an anthrax (1838); and a rose has been named after him since 1860.
