Johann Gutenberg was born around 1400 in Mainz, Germany.¹⁾

He is best known for inventing the movable-type printing press around 1440, a significant development that revolutionized the spread of knowledge.²⁾

Gutenberg's most famous work is the Gutenberg Bible, also known as the 42-line Bible, printed around 1455. It was the first major book printed using movable type in the West.³⁾

The Gutenberg Bible contained 1,282 pages and was printed in Latin. Only around 180 copies of it were made, and they are now highly valuable collector's items.⁴⁾

Gutenberg's press utilized individual metal letters that could be rearranged to compose different texts, allowing for efficient mass production of books.⁵⁾

Before his invention, books were laboriously handwritten, making them expensive and rare.⁶⁾
