From Wikipedia: Johannes Gensfleisch zur Laden zum Gutenberg (c. 1393–1406 – 3 February 1468) was a German inventor and craftsman who introduced letterpress printing to Europe with his movable-type printing press. Though movable type was already in use in East Asia, Gutenberg invented the printing press, which later spread across the world. His work led to an information revolution and the unprecedented mass-spread of literature throughout Europe. It also had a direct impact on the development of the Renaissance, Reformation and humanist movements, as all of them have been described as "unthinkable" without Gutenberg's invention.

His many contributions to printing include the invention of a process for mass-producing movable type; the use of oil-based ink for printing books; adjustable molds; mechanical movable type; and the invention of a wooden printing press similar to the agricultural screw presses of the period. Gutenberg's method for making type is traditionally considered to have included a type metal alloy and a hand mould for casting type. The alloy was a mixture of lead, tin, and antimony that melted at a relatively low temperature for faster and more economical casting, cast well, and created a durable type. His major work, the Gutenberg Bible, was the first printed version of the Bible and has been acclaimed for its high aesthetic and technical quality.

Described as the "man of the millennium", Gutenberg is often cited as among the most influential figures in human history. He has been commemorated around the world and is a frequent namesake. To celebrate the 500th anniversary of his birth in 1900, the Gutenberg Museum was founded in his hometown of Mainz.
