Félix Vicq d'Azyr (French: [feliks vik daziʁ]; 23 April 1746 – 20 June 1794) was a French physician and anatomist, the originator of comparative anatomy and discoverer of the theory of homology in biology.
From 1773 Vicq d'Azyr taught a celebrated course of anatomy at the Jardin du Roi, currently the Museum of Natural History, in Paris. In 1774 he was elected a member of the Académie des Sciences with the support of his friend Condorcet, the Perpetual Secretary. In this latter capacity, he was in charge of writing the eulogies of his colleagues. This he accomplished with great talent, thus winning a lifetime membership to the Académie française in 1788. On the outbreak of an epidemic in Guyenne he was charged with writing a report, of making propositions and with their execution. Pursuing an early perception of the responsibility of the State on health affairs, Anne-Robert-Jacques Turgot proposed the creation of the Société Royale de Médecine. In 1775, Vicq d'Azyr was made Perpetual Secretary. Under his leadership, the Société compiled over 16 years a great mass of facts and information about diseases, physicians, economics and food resources.
As an anatomist he was one of the first to use coronal sections of the brain and to use alcohol to aid dissection. He described the locus coeruleus, the locus niger (substantia nigra) in the brain, in 1786, and the band of Vicq d'Azyr, a fiber system between the external granular layer and the external pyramidal layer of the cerebral cortex, as well as the Mamillo-thalamic tract, which bears his name. His systematic studies of the cerebral convolutions became a classic and Vicq d'Azyr was one of the first neuroanatomists to name the gyri. He studied the deep gray nuclei of the cerebrum and the basal ganglia. He participated in the Second Encyclopedia.
A collection of some of his papers is held at the National Library of Medicine in Bethesda, Maryland.
