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.
Johannes Gutenberg was a German goldsmith and inventor best known for the Gutenberg press, an innovative printing machine that used movable type. Gutenberg was born between 1394 and 1400 and died in 1468. In 1438, Gutenberg began a business arrangement with Andreas Dritzehn, who funded his experiments in printing. In 1450, Gutenberg began a second arrangement with German businessman Johannes Fust.
