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.
The first bound parchment books, or codices, were the Bibles of the early Christian church, like the 4th century A.D. Codex Vaticanus and the Codex Sinaiticus. Much later, in 1454 or 1455, Johann Gutenberg printed the first book on a moveable-type printing press: the Gutenberg Bible.
