1 BC · 1 AD
Estimated range: 1440 AD to 1455 AD
Context
What happened?
Johannes Gutenberg combined movable metal type, oil-based ink, and a press-based production process in fifteenth-century Mainz. The work developed over time rather than on one documented invention date, which is why QuoAnno uses a range from 1440 to 1455 AD.
Significance
Why it matters
The system made it possible to reproduce books in Europe more quickly and consistently at scale. Movable-type printing had existed earlier in East Asia, while Gutenberg’s particular process became central to the rapid expansion of European print culture.
