Gabriel-Madeleine-Camille Dareste de la Chavanne (22 November 1822, in Paris – 1899, in Paris) [1] was a French zoologist and specialist in experimental embryology.
He obtained his doctorate in medicine in 1847 and his doctorate in science in 1851. He worked at the University of Lille, where he was chair to the faculty of natural history from 1864 to 1872. In 1872 he was appointed professor of ichthyology and herpetology at the Museum d'Histoire Naturelle in Paris. He was named director of the laboratory of teratology, and from 1875, associated with the École des Hautes-études. He was awarded the grand prize in physiology by the Académie des sciences for the treatise Recherches sur la production artificielle de monstruosités (1877).[2]
He was a founder of teratogeny, it being defined as the experimental study of conditions for the artificial production of monstrosities.[3] Beginning in 1855, he purposely produced monstrous chick embryos by using "indirect methods" that exposed the egg to teratogenic factors — such as, implementing lowered incubation temperatures for several hours.[4]
