About Marie Jules César Savigny

Marie Jules César Lelorgne de Savigny was a French zoologist and naturalist who served on Emperor Napoleon's Egypt expedition in 1798. He published descriptions of numerous taxa and was among the first to propose that the mouth-parts of insects are derived from the jointed legs of segmented arthropods. Savigny became responsible for studying invertebrates, while Étienne Geoffroy Saint-Hilaire took care of the vertebrates.
