The German inventor and printer Johann Gutenburg was the inventor of movable-type mechanical printing in Europe. Johann Gutenburg was born Johann Gensfleisch zur Laden, in Mainz. He was the third child of Freile zum Gensfleisch and his second wife, Else Wirick zum Gutenburg, whose name Johann adopted.

The printing press allowed the Renaissance to spread because it made new ideas available to a much larger audience. A printing press is a mechanical device for applying pressure to an inked surface. It's made of bronze and perhaps tin was also used in China for the printing of books. His invention revolutionized book making in Europe. Gutenburg was the key figure in spreading the Renaissance.

The Gutenburg bible was among the earliest major books printied using mass produced movable metal type in Europe. The bible that is a printed book that we study and pray through individually. The press was in many ways a great gift to the Church, enabling the Bible to become the world's bestselling printed book to date.

His printing press has been widely considered the most imporant invention of the modern era because it profoundly impacted the transmission of knowledge.
