Henry Chapman Mercer (1856-1930). Archaeologist, scholar, collector, tile maker. Mercer was born and worked in Doylestown. Between 1908 & 1916, he designed and built three unique concrete structures: Fonthill, his castle-like home; the Moravian Pottery & Tile Works, where he made his distinctive handcrafted products; and the Mercer Museum, site of his vast collection of early Americana. His patented tile mosaics decorate the Pennsylvania State Capitol.
