Around February 23, 1455, Johannes Gutenberg completed printing the first substantial book produced with movable metal type in Europe: the Gutenberg Bible. A Latin Vulgate, 1,282 pages, set in two columns of 42 lines each. Approximately 180 copies were printed. Forty-nine survive today. A complete copy is estimated at $25 to $35 million.
Gutenberg didn't invent printing. The Chinese had used woodblock printing for centuries, and movable type existed in Korea. What Gutenberg engineered was a system: durable metal type, oil-based ink, and a press adapted from wine presses. It required 290 distinct character molds. Precision manufacturing in an era of handcraft.
Before Gutenberg, European books were copied by hand, mostly by monks. A single Bible could take a scribe two years. Gutenberg's press broke the monopoly on knowledge. Within fifty years, an estimated 20 million volumes were in circulation. By 1600, that number reached 200 million.

Gutenberg himself went bankrupt. His backer Johann Fust sued for loan repayment, won, and seized the equipment and inventory. Gutenberg died around 1468, largely forgotten. His press, however, fueled the Reformation, the Scientific Revolution, and the Enlightenment. Luther's 95 Theses spread across Germany in two weeks. Without Gutenberg, Luther is a local theologian with a complaint.
The Bible is beautiful, but its beauty is incidental. What mattered was reproducibility. One book, copied exactly, distributed widely. That's the invention that rewired civilization. Every mass medium since, from newspapers to the internet, descends from a press in Mainz.
