1881 William Pengelly (12 January 1812-16 March 1894). Walker and Boutall photoengravure after painting by A. S. Cope. Being a Frontispiece with later tinting to \A Memoire of William Pengelly\" by his daughter Hester 1897. A self taught geologist, he was the first to excavate at Brixham cave in 1858. He accurately recorded layer by layer the chronology of deposits, and found flint implements and extinct mammal remains comingled in the same layers ( \"men were amongst the mammoths'). The Geological Society overseer was Hugh Falconer. He saw the importance of these finds and later set up Evans and Prestwich to check the similar discounted reports of Boucher de Perthes in France. The result was a cascading and revolutionary new acceptance of human antiquity on both sides of the channel. Pengelly went on to supervise similar carefull work at Kent's Cavern producing more pre-historic remains."
