In the mid-15th century, owning a book was a mark of extreme wealth. A single hand-copied Bible could cost as much as a small farm, requiring a trained scribe an entire year of labor to produce. Books were so valuable they were often chained to library shelves to prevent theft. Written knowledge was a treasure locked away, accessible only to the clergy, royalty, and a handful of elites. A German goldsmith from Mainz named Johannes Gutenberg saw this bottleneck not as a fact of life, but as a problem to be solved. He believed he could create a machine that could reproduce texts quickly and cheaply, unlocking the world of ideas for everyone. His ambition would challenge the very structure of society.

Frequently Asked Questions
How were books made before the printing press?
Before the printing press, books were copied by hand by trained scribes. This was an incredibly slow and expensive process; a single Bible could cost as much as a small farm and take a scribe an entire year to complete.
What was Johannes Gutenberg's most important invention?
Gutenberg's key innovation was the hand mold, a device that allowed a worker to quickly cast thousands of identical metal letters. He used a unique alloy of lead, tin, and antimony that cooled instantly and created sharp, durable type.
Why did printing spread so quickly across Europe?
The technology was initially a closely guarded secret in the city of Mainz. However, the 1462 Sack of Mainz forced many trained printers to flee, and they established new workshops in other countries like Italy and France, spreading the knowledge across the continent.
