Boucher de Crèvecœur de Perthes, Jacques (zhäk bōshāˈ də krĕvkörˈ də pĕrt) [key], 1788–1868, French writer and archaeologist. He was the first to provide evidence that humans had existed in the Pleistocene epoch, thereby disputing the theory of diluvial catastrophism. He collected flint artifacts near Abbeville, France, and demonstrated that these manufactured objects came from the same stratum as Ice Age fauna. See Paleolithic period.
