What happened
Johannes Gutenberg, a goldsmith from Mainz, adapted the mechanics of wine and oil presses to build a press that used reusable metal movable type, letting a single press produce many identical copies of a text far faster than hand-copying. By 1448 Gutenberg had returned to Mainz and borrowed money from his brother-in-law Arnold Gelthus, likely to finance the press, and by 1450 his workshop was operating, with its first known printed work believed to be a short poem called The Sibyl's Prophecy. That same year Gutenberg secured a further 800 guilders from the financier Johann Fust, using his printing equipment as collateral, funding that would later lead to Fust seizing the press in a legal dispute.
Why it matters
Movable-type printing spread from Mainz to roughly 270 European cities within a few decades, and by 1500 European presses had produced more than twenty million printed items. That infrastructure is precisely what let Martin Luther's writings spread across German-speaking lands within weeks rather than years two generations later, making the Reformation possible as a mass movement rather than a local university dispute.
How we know
Gutenberg's activities are documented through surviving legal and financial records from Mainz, including the loan and lawsuit documents connected to Johann Fust, alongside the surviving printed works themselves, most famously the 42-line Gutenberg Bible produced by his workshop in the 1450s.
