The invention attributed to Johannes Gutenberg in the 15th century is the movable-type printing press. Invented around 1440, this revolutionary technology allowed for the mass production of books and printed materials, dramatically reducing the time and cost associated with book production compared to hand copying. Gutenberg's printing press played a crucial role in promoting literacy, spreading knowledge, and facilitating the dissemination of ideas during the Renaissance. The most famous printed work, the Gutenberg Bible, showcased this innovative technology's capabilities and is considered one of the first major books produced using movable type.
