André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist, and the author citation Duméril is used for both André and his son. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the prévot of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris. Under the Restauration, he was elected a member of the Académie des Sciences (French Academy of Sciences) and after 1803 succeeded Lacépède, who was occupied by his political offices, as professor of herpetology and ichthyology at the Muséum national d'histoire naturelle. Duméril only officially received this chair in 1825, after the death of Lacépède. He published his Zoologie analytique in 1806. This covered the whole of the animal kingdom and shows the relations between genera as then distinguished, but not among species. He was elected a member of the American Philosophical Society in Philadelphia in 1813. In 1832, Gabriel Bibron (1806–1848), who became his assistant, was given the task of describing the species for an expanded version of Zoologie analytique, while Nicolaus Michael Oppel (1782–1820) assisted him with a revised higher-order systematics. After the death of Bibron, he was replaced by Auguste Duméril, André's son. However, Bibron's death delayed the publication of the new work for 10 years. In 1851, the two Dumérils, father and son, published the Catalogue méthodique de la collection des reptiles (although Auguste was apparently the true author) and in 1853, André Duméril alone published Prodrome de la classification des reptiles ophidiens. This last book proposes a classification of all the snakes in seven volumes. Duméril, upon discovering a case of preserved fishes in the attic of the house of Georges-Louis Leclerc, Comte de Buffon, finally described the species that had been collected by Philibert Commerson nearly 70 years earlier. He then published a very important work,
