c. 1400-1468. German printer, the inventor of printing from moveable metal type, based on the Chinese wood-block-type method (although Laurens Janszoon Coster has a rival claim). Gutenberg began work on the process in the 1430s and in 1440 set up a printing business in Mainz with Johann Fust (c. 1400-1466) as a backer. By 1455 he produced the first printed Bible (known as the Gutenberg Bible). Fust seized the press for nonpayment of the loan, but Gutenberg is believed to have printed the Mazarin and Bamberg bibles.
