Henry Chapman MercerDied 9 Mar 1930 at age 73 (born 24 Jun 1856).American archaeologist, collector, and tilemaker. In his early years, he pursued archaeology. In 1897, while searching for fireplace tools in a junk dealer's barn, Mercer found a jumble of American Pioneer handicraft tools made obsolete by the Industrial Revolution. He realized these pre-1850 work related implements might one day be the prized findings of future archeologists. Mercer seized upon opportunity to preserve such endangered artifacts. He spent a lifetime building his collection, which he called "The Tools of the Nation Maker." In 1898, he founded the Moravian Pottery and Tile Works in Doylestown, PA., to manufacture hand-worked relief-decorated ceramic tiles by a system he developed and patented. |
