Thomas K. Ford, The Leatherworker in Eighteenth-Century Williamsburg
“ The ancient Sumerians, Babylonians, Assyrians, Egyptians, central Asians, and Chinese all knew tanned leather and used it. But who first discovered how to tan it, when that happened, and where, must remain forever unanswered, since the invention of tanning came before the invention of written records. Primitive leatherworkers probably stumbled on different processes at different times and places, and quite possibly a number of widely separated workers discovered the same processes independently. ”
