Johannes Gutenberg
German craftsman (c. 1400–1468) whose invention of movable type printing (~1440) triggered the most consequential information revolution in human history, making the Protestant Reformation, Scientific Revolution, and modern nationalism all possible.
The printing press is the ultimate example of technology as social dynamite. Before Gutenberg, books were hand-copied, expensive, rare, and controlled by Church institutions. A Bible cost a year's wages. After Gutenberg, a Bible could be produced for the price of a few days' work. Within 50 years of the press's invention, an estimated 20 million books circulated in Europe, more than had existed in the previous thousand years combined.
The implications were revolutionary in every sense. The Protestant Reformation (1517) was enabled by the press: Luther's 95 Theses spread across Germany in two weeks because printers could reproduce them instantly. Without the press, Luther would have been another Jan Hus, burnt at the stake and quickly forgotten.
The press also enabled what Benedict Anderson called 'imagined communities': by standardizing vernacular languages in print, it created the shared textual spaces that made nationalism possible. People who never met could feel they belonged to the same German, French, or English people because they read the same language in print.
