Definition of Boucher de Perthes, Jacques in English:

(1788–1868), French archaeologist. In 1837 he discovered some of the first evidence of man-made stone tools near the bones of extinct (Pleistocene) animals in the valley of the River Somme. He argued that these tools (and their makers) belonged to a pre-Celtic ‘antediluvian’ age, but his findings were not accepted until the 1850s.
