The Mainz Psalter, printed by Johann Fust and Peter Schöffer, was the first book to bear the printer's name and date of publication. This was a significant event in the history of printing, as it marked a departure from the anonymity of earlier printed works and established a precedent for identifying the producers of printed materials. Ironically, it did not mention Gutenberg, despite him being the inventor of the technology that made its production possible.
