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.
