Georges Louis Duvernoy, a French naturalist, born in Montbeliard, Aug. 6, 1777, died in Paris, March 1, 1855. He pursued his studies at Stuttgart, Strasburg, and Paris, and in 1802 was invited by Cuvier, to whom he was related, to assist in editing his treatise on comparative anatomy. With the aid of the notes and counsels of his master, he prepared the last three volumes of this work, embracing the organs of digestion, respiration, circulation, generation, and the secretions. For 20 years he practised medicine in Montbeliard, publishing only a few writings on fossils. In 1827 he was elected professor of natural history at Strasburg, where during ten years he published a variety of papers on anatomical subjects; and after the death of Cuvier he was engaged in arranging his papers for publication. In 1837 he was elected professor of natural history in the college de France, and in 1850 was transferred to the chair of comparative anatomy. His numerous works have furnished important materials to anatomists and zoologists.
