AT A GLANCE: In 1440, German inventor Johannes Gutenberg invented a printing press process that, with refinements and increased mechanization, remained the principal means of printing until the late 20th century.
Johannes Gutenberg got rid of the woodblock ideas and tried to work with metal. He decided it worked very well and was completing the first book ever printed by his new invention, which was movable type. The first book was the Bible, which was printed in Latin. His invention was called the printing press. Soon enough the blacksmith that Johannes Gutenberg was working for lost faith in him and decided to take him to court. The judge favored with Fust, so everything Gutenberg worked on and owned belonged to Fust. Johannes Gutenberg ended up dying in Mainz, Germany in 1468.
