Jacques Boucher de Crèvecœur de Perthes is considered to be one of the founding fathers of prehistory. President of the Société d'émulation d'Abbeville, he aimed to prove the existence of “antediluvian” man through his research in the fluvial terraces of the Somme. The publication of his Antiquités celtiques et antidiluviennes in 1858 laid the foundations of prehistory. He gave his many collections to the musée gallo-romain, where they were displayed in room 1.
