Henri Coquand

Henri Coquand (1813, in Aix-en-Provence – 1881, in Marseille) was a French geologist and paleontologist.

In 1841 he obtained his doctorate in sciences in Paris, and later served as professor of geology at the Universities of Besançon, Poitiers and Marseille.[1]

From his geological studies of southwestern France, he introduced the Upper Cretaceous stages: Coniacian, Santonian and Campanian (1857).[2] In 1871 he proposed the Berriasian stage of the Lower Cretaceous, named after Berrias, a town in the department of Ardèche.[3] He also conducted geological / paleontological research in Spain, Algeria and Morocco.[1]

In 1838 he founded the Muséum d'Aix in Aix-en-Provence.[4] From 1862 to 1870 he was a correspondent member of the Comité des travaux historiques et scientifiques, and from 1871 to 1881, he was a munincipal councillor in Marseille.[1]

The mineral "coquandite" commemorates his name; chemical formula= Sb6O8(SO4)o(H2O).[5]
