At the time Rittenhouse arrived in Germantown there was a printer, William Bradford, already established in an office in Philadelphia, and it may be that he induced the paper-makers to locate there. Anyway they no sooner settled at Germantown than they began the erection of a paper mill, on property purchased from Samuel Carpenter, of Philadelphia. It appears from the original deed that William Bradford, Robert Turner and Thomas Tresse were interested with William Rittenhouse in the enterprise. They were deeded twenty acres. The mill was built, but soon thereafter Robert Turner died, and Bradford and Tresse assigned their rights to William Rittenhouse, who became the sole owner. Their deed for this property was acknowledged December 6, 1693. The term of the lease was for 975 years from the 29th of September, 1705, and the rent reserved was five shillings sterling per annum. It thus appears that there was at first a company regularly organized to establish a paper mill. Samuel Carpenter and Robert Turner were extensive land owners and were advisers and coadjutors of William Penn. Thomas Tresse was a rich iron monger and William Bradford was the famous printer who established the first printing press in the middle colonies of America, in 1685. The chief and most important member of this company was William Rittenhouse, who became the sole proprietor prior to 1705, unless the interest of Tresse was purchased by Claus Rittenhouse, about 1701. It also seems that the son bought Bradford’s interest in 1704. Father and son were practical papermakers and the owners. Bradford got himself into trouble when he printed the charter without leave of the ruling powers, and then for printing a pamphlet of George Keith, a seceding Scotch Quaker. He was arraigned in court, and in 1693 left Philadelphia and established himself in New York, where he introduced the first printing plant in that province. When Bradford left Philadelphia he was to receive for his share of the mill paper of the value of six pounds, two shillings, and the assurance that he had a monopoly of the entire printing paper that was made in America from September 1, 1697, until September 1, 1707. The quantity is not stated, neither is there anything by which we can determine, at this late day, the capacity of the mill. All paper was then manufactured by hand, each sheet being made separately. At that early day and long afterward the rags were pounded into pulp in stone and iron mortars by the aid of trip-hammers, and several days were required to furnish a sample sheet of dry-finished paper. At that time a day’s production per man was one and a half reams of newspaper of the size of 20 by 30 inches. Small as was this mill, its importance can hardly be understood, for the greatest commercial metropolis of America drew its supply of printing paper from this mill.
