Context
In medieval Europe, books were copied by hand, primarily by monks in monasteries. A single Bible could take a scribe over a year to produce. Literacy was confined to the clergy and wealthy elite. Knowledge was hoarded, not shared. The Chinese had developed woodblock printing centuries earlier, but movable type had not yet reached Europe.
The Deed
Gutenberg developed a complete system: individual metal letter molds cast from a lead-tin-antimony alloy, an oil-based ink that adhered to metal type, and a wooden screw press adapted from wine and olive presses. Each component was an innovation. His masterpiece, the Gutenberg Bible of 1455, demonstrated print quality that rivaled the finest handwritten manuscripts. Within 50 years, over 20 million volumes had been printed across Europe.
Why It Matters
The printing press broke the Church and aristocracy's monopoly on knowledge. Scientific discoveries could be shared across borders within weeks instead of decades. Martin Luther's 95 Theses spread across Germany in two weeks. The Reformation, the Scientific Revolution, and the Enlightenment are all downstream of Gutenberg's press.
Brutal Truth
Gutenberg himself went bankrupt. His financial backer Johann Fust seized his equipment and completed the Bible project, reaping the profits. Gutenberg died in relative obscurity in 1468. The man who democratized information never benefited from his own revolution.
