Home Johann Gutenberg Johann Gutenberg. Johann Gutenberg invented the printing press in the 1450's, and the first book to ever be printed was a Latin language Bible, printed in Mainz, Germany. Gutenberg's Bibles were surprisingly beautiful, as each leaf Gutenberg printed was later colorfully hand-illuminated.
In 1450 Gutenberg borrowed a considerable sum of money from Johann Fust, a wealthy businessman and moneylender. The loan funded the construction of printing equipment for another workshop, which was large enough to accommodate the inventorâs next and most ambitious project, the 42-line Bible. Gutenberg viewed printing as a craft, not as a replacement for handwriting.
