About Marie Jules César Savigny
Marie Jules César Lelorgne de Savigny (French: [maʁi ʒyl sezaʁ ləlɔʁɲ də saviɲi]; 5 April 1777 – 5 October 1851) 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.
