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.
1 Books produced in this period, between the first work of Johann Gutenberg in 1450 and the year 1500, are collectively referred to as incunabula. 2  Gutenberg changed plans at least three times while printing the Bible. 3  The Bible that Gutenberg printed was a Latin translation from about 380 AD.
