In 1811, Elihu White established a type-foundry in New York. He had been long engaged, in connection with Mr. Wing, in the manufacture of printing types at Hartford, Connecticut, upon a plan of their own invention, by which twenty or thirty letters were cast at once; but, abandoning that invention, he adopted the old plan of casting, and, having a good assortment of faces and bodies, his removal to New York was a great convenience to its printers, and they gave him a very satisfactory support. But the principal business in type-founding still continued, as formerly, to be carried on in Philadelphia. In 1813, another type-foundry was begun in the city of New York, by D. & G. Bruce, principally to cast types for their own use. They had carried on book-printing for seven years, and had now become acquainted with the stereotype art,—Mr. David Bruce having visited England in 1812 and acquired it by purchase and actual labour. For ordinary printing, it was customary to bevel off the body of the type at the face end, or shoulder, as it is usually called, which unfitted it for making a strong stereotype plate in the most approved way: hence the necessity for casting type expressly for stereotype. Their first fount was Bourgeois, with which they cast two sets of plates of the New Testament, (the Common School Testament,) and sold one of these to Mathew Carey, of Philadelphia, retaining the other for their own business. But these were not completed till 1814. In 1815, they cast the plates of the 12mo School Bible, on Nonpareil type, prepared, like the Bourgeois, at their own foundry expressly for stereotyping. They thus gave the first stereotype School Testament and School Bible to America; but not the first stereotype book. John Watts, of England, also commenced stereotyping in New York in 1813, and completed the Westminster Catechism that year, a volume of 120 pages 12mo. David Bruce invented the planing-machine for equalizing the thickness of stereotype plates, which is now used in every stereotype foundry in the United States. The process of stereotyping is, however, entirely different from that of ordinary type-founding, and it is, therefore, generally carried on as a separate business, or connected with the composing department of a printing-office. Twenty compositors and two proof-readers will furnish full employment for one moulder, one caster, and three finishers, who will, among them, complete, on an average, 50 pages of octavo per day.
