Johannes Gutenberg was born in 1398 in Mainz, Germany and learned the trade of metalworking and goldsmithing from his family. He worked for many years developing his skills and inventing the first movable type printing press, which allowed books to be printed affordably and in mass quantities. In 1450, Gutenberg completed his printing press invention after taking out several loans. His next project was printing the first mass produced Bible, helping more people to interpret scripture. Gutenberg largely went unknown for his invention during his life, but he changed the world by creating one of the greatest inventions of all time.
