Raymond Sabouraud
Raymond Jacques Adrien Sabouraud (24 November 1864 – 4 February 1938) was a French physician born in Nantes. He specialized in dermatology and mycology, and was also an accomplished painter and sculptor.

He studied medicine in Nantes and Paris, and worked as a hospital interne at the Hôpital Saint-Louis under Ernest Besnier and at the Hôpital des Enfants-Assistés under Edouard Francis Kirmisson. Afterwards he studied bacteriology with Pierre Paul Émile Roux at the Pasteur Institute. In 1894 he received his doctorate, and he later served as chief of Jean Alfred Fournier's laboratory at the Hôpital Saint-Louis.

In 1904, Sabouraud introduced radiological treatment against ringworm of the scalp. He was well known for his knowledge of scalp diseases, and had a clinic which attracted patients from all over the world.

He invented a method to select fungi with a medium of low pH and a rather high concentration of sugar. This medium, called Sabouraud agar is named after him.

With Ferdinand-Jean Darier (1856–1938) and Henri Gougerot (1881–1955), he was the editor of an eight-volume encyclopedia of dermatology titled Nouvelle Pratique Dermatologique. His Manuel élémentaire de dermatologie topographique régionale (1905), was translated into English and published as Elementary Manual of Regional Topographical Dermatology (1906), and several years later re-published as A Manual of Regional Topographical Dermatology (1912).
