who developed the first printing press in 1430s
Johannes Gutenberg
title: Printing press text: Printing press A printing press is a device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. Johannes Gutenberg, a goldsmith by profession, developed, circa 1439, a printing system by adapting existing title: History of printing text: a 1439 lawsuit against Gutenberg that official record exists; witnesses testimony discussed type, an inventory of metals (including lead) and his type mold. Others in Europe were developing movable type at this time, including goldsmith Procopius Waldfoghel of France and Laurens Janszoon Coster of the Netherlands. They are not known to have contributed specific advances to the printing press. While the Encyclopædia Britannica Eleventh Edition had attributed the invention of the printing press to Coster, the company now states that is incorrect. Early printing houses (near the time of Gutenberg) were run by "master printers." These printers owned shops, selected title: Printing press text: antiquity in Gutenberg's time and was used for a wide range of tasks. Introduced in the 1st century AD by the Romans, it was commonly employed in agricultural production for pressing wine grapes and (olive) oil fruit, both of which formed an integral part of the mediterranean and medieval diet. The device was also used from very early on in urban contexts as a cloth press for printing patterns. Gutenberg may have also been inspired by the paper presses which had spread through the German lands since the late 14th century and which worked on the same mechanical principles. Gutenberg title: Printing press text: Gutenberg's work on the printing press began in approximately 1436 when he partnered with Andreas Dritzehn—a man who had previously instructed in gem-cutting—and Andreas Heilmann, owner of a paper mill. However, it was not until a 1439 lawsuit against Gutenberg that an official record existed; witnesses' testimony discussed Gutenberg's types, an inventory of metals (including lead), and his type molds. Having previously worked as a professional goldsmith, Gutenberg made skillful use of the knowledge of metals he had learned as a craftsman. He was the first to make type from an alloy of lead, tin, and antimony, which was critical title: History of printing text: American colonies in 1638, but died on the voyage, so his widow, Elizabeth Harris Glover, established the printing house, which was run by Stephen Day and became The Cambridge Press. The Gutenberg press was much more efficient than manual copying. It remained largely unchanged in the eras of John Baskerville and Giambattista Bodoni, over 300 years later. By 1800, Lord Stanhope had constructed a press completely from cast iron, reducing the force required by 90% while doubling the size of the printed area. While Stanhope's "mechanical theory" had improved the efficiency of the press, it was only capable of 250
