Moveable Type

Throughout the centuries, scribes would laboriously write and illustrate the written word, one letter at a time, for the privileged few. Johann Gutenberg revolutionized the world by inventing moveable type for printing in 1450. Gutenberg almost single-handedly put an end to the Dark Ages with the printed page for the masses. The printed page consisted of Gutenberg's moveable type, engravings on wood blocks, steel and copper plates. Portraits and details concerning Gutenberg's creation are contained in the Mertle Collection.

Lithography

Alois Senefelder invented the process of lithography in the late 1700's. Bavarian limestone was imaged, inked and used to print for the masses. Ink and water mixtures were used as the imaging medium in a lithographic press. No moveable type, only the hand of the artist and engraver was needed to image the litho stone. A new medium was created to provide a printed sheet of paper for the masses. Litho stone illustrations and commentary are contained in the Mertle Collection.
