Émile Vidal

Jean Baptiste Émile Vidal (18 June 1825 – 16 June 1893) was a French dermatologist who was a native of Paris.

He studied medicine in Tours and Paris, becoming médecin des hôpitaux in 1862. For much of his career he was associated with the Hôpital Saint-Louis (1867–1890) in Paris. In 1883 he became a member of the Académie de Médecine.

He is remembered for his investigations of lupus and skin lichenification. His name is associated with "pityriasis circinata et marginata of Vidal", a disorder that is synonymous to pityriasis rosea, and "Vidal's disease", an historical name for lichen simplex chronicus.
