Blainville, Henri Marie Ducrotay De (1777-1850), French naturalist, was born at Arques, near Dieppe, on the 12th of September 1777. About 1796 he went to Paris to study painting, but he ultimately devoted himself to natural history, and attracted the attention of Baron Cuvier, for whom he occasionally lectured at the Collège de France and at the Athenaeum. In 1812 he was aided by Cuvier to obtain the chair of anatomy and zoology in the Faculty of Sciences at Paris, but subsequently an estrangement grew up between the two men and ended in open enmity. In 1825 Blainville was admitted a member of the Academy of Sciences; and in 1830 he was appointed to succeed J.B. Lamarck in the chair of natural history at the museum. Two years later, on the death of Cuvier, he obtained the chair of comparative anatomy, which he continued to occupy for the space of eighteen years, proving himself no unworthy successor to his great teacher. He died at Paris on the 1st of May 1850. Besides many separate memoirs, he was the author of Prodrome d’une nouvelle distribution méthodique du règne animal (1816); Ostéographic ou description iconographique comparée du squelette, &c. (1839-1864); Faune française (1821-1830); Corns de physiologie générale et comparée (1833); Manuel de malacologie et de conchyliologie (1825-1827); Histoire des sciences de l’organisme (1845).
