Louis Fage
Louis Fage, also known as Jean-Louis Fage and Baptiste Louis Fage, was a French marine biologist and arachnologist.
A native of Limoges, he studied biology at the Sorbonne and in the laboratory at Saint-Vaast-la-Hougue. In 1906 he obtained his doctorate with a thesis on the nephridia of polychaetes. For the next fourteen years he served as a naturalist at the Laboratoire de biologie marine in Banyuls-sur-Mer. From 1920 he worked in the zoology department at the Muséum national d'histoire naturelle in Paris, where in 1938 he succeeded Charles Joseph Gravier as professor and director of the department of zoology.
Fage made contributions in the fields of carcinology, arachnology and speleology. In 1945 he was a founding member of the Commission de spéléologie. He also performed research of Ellobiopsis. A genus of ammonites named Fagesia is named after him.
