5. The statements which seem to be the most worthy of credit, bestow the honor of this invention on a citizen of Mentz. Here, it appears, that John Geinsfleisch, or Guttemburg senior, published two small works for schools, in 1442, on wooden types; but, not having the funds necessary to carry on the business, he applied to John Faust, a rich goldsmith, who became a partner, in 1443, and advanced the requisite means. Soon afterwards, J. Meidenbachius and some others were admitted as partners. 6. In the following year, John Guttemburg, the brother of Geinsfleisch, made an addition to the firm. For several years before this union, or from 1436, Guttemburg had been attempting to complete the invention at Strasburg; but it is said that he had never been able to produce a clean printed sheet. The brothers may, or may not, have pursued their experiments without receiving any hints from each other, before their union at Mentz. 7. Soon after the formation of this partnership, the two brothers commenced cutting _metal types_, for the purpose of printing an edition of the Bible, which was published in Latin, about the year 1450. Before this great achievement of the art had been effected, Geinsfleisch appears to have retired from the concern, some say, on account of blindness. 8. The partnership before mentioned, was dissolved, in 1450, and Faust and Guttemburg entered into a new arrangement, the former supplying money, the latter, personal services, for their mutual benefit; but various difficulties having arisen, this partnership was also dissolved, in 1455, after a lawsuit between them, which was decided against Guttemburg. 9. Faust, having obtained possession of the printing materials, entered into partnership with Peter Shoeffer, who had been for a long time a servant, or workman, in the printing establishment. In 1457, they published an edition of the _Psalter_, which was then considered uncommonly elegant. This book was, in a great measure, the work of Guttemburg, since, during the four years in which it was in the press, he was, for two years and a half, the chief operator in the printing-office. 10. Guttemburg, by the pecuniary aid of Conrad Humery and others, established another press in Mentz, and, in 1460, published the "_Catholicon Joannis Januensis_." It was a very handsome work, but not equal in beauty to the Psalter of Faust and Shoeffer. The latter was the first printed book known to have a genuine date. From this time, it has been the practice for printers to claim their own productions, by prefixing to them their names.
