Johannes Gutenberg

Johannes Gensfleisch zur Laden zum Gutenberg; }} ( – 3 February 1468) was a German inventor and craftsman who invented the movable-type printing press. Though movable type was already in use in East Asia, Gutenberg's invention of the printing press enabled a much faster rate of printing. The printing press later spread across the world, and led to an information revolution and the unprecedented mass-spread of literature throughout Europe. It had a profound impact on the development of the Renaissance, Reformation, and humanist movements.

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.

Gutenberg is often cited as among the most influential figures in human history and has been commemorated around the world. To celebrate the 500th anniversary of his birth in 1900, the Gutenberg Museum was founded in his hometown of Mainz. In 1997, Time Life magazine picked Gutenberg's invention as the most important of the second millennium. Provided by Wikipedia
