Johannes Gutenberg

Johannes Gensfleisch zur Laden zum Gutenberg (c. 1400 – February 3, 1468) was a German goldsmith and printer, who is credited with inventing movable type printing in Europe (ca. 1450) and mechanical printing globally. His major work, the Gutenberg Bible, also known as the 42-line bible, has been acclaimed for its high aesthetic and technical quality.

Among Gutenberg's specific contributions were the design of metal movable type, the invention of a process for making such type in quantity (mass production), the use of oil-based ink, and the use of a wooden printing press similar to the screw olive and wine presses of the period. His truly epochal invention was the combination of these elements into a practical system. Gutenberg may have been familiar with printing; it is claimed that he had worked on copper engravings with an artist known as the Master of the Playing Cards. Gutenberg's method for making type is traditionally considered to have included a type metal alloy and a hand mould for casting type.

The use of movable type was a marked improvement on the handwritten manuscript, which was the existing method of book production in Europe, and upon woodblock printing, and revolutionized European book-making. Gutenberg's printing technology spread rapidly throughout Europe and is considered a key factor in the European Renaissance. Gutenberg remains a towering figure in the popular image; in 1999, the A&E Network ranked Gutenberg #1 on their "People of the Millennium" countdown, and in 1997, Time–Life magazine picked Gutenberg's invention as the most important of the second millennium.
