Gutenberg's Printing Press

Around 1440, Johannes Gutenberg of Mainz, Germany, developed the movable-type printing press, one of the most transformative inventions in human history. Before Gutenberg, books had to be copied by hand, making them extremely expensive and rare. Gutenberg's press used individual metal letter blocks that could be rearranged and reused. His first major printed work, the Gutenberg Bible (around 1455), demonstrated that books could be produced quickly and cheaply. Within 50 years, an estimated 20 million volumes had been printed in Europe. The printing press democratized knowledge, fueled the Renaissance and Reformation, enabled the Scientific Revolution, and laid the groundwork for mass communication. It is often compared to the invention of the internet in its impact on society.
