Gutenberg's genius was combining four old inventions, including a wine press
The printing press that transformed Europe around 1440 was built largely from borrowed parts: a Roman-era screw press used for grapes and olives, movable type, the book format and cheap mill-made paper. A former goldsmith, Johannes Gutenberg, fused them into one system and added the crucial pieces himself.
Demand was waiting. Towns and trade had swelled an urban middle class, universities founded since the twelfth century wanted books, and slow, costly hand-copying could not keep up. Paper had become cheap after water-powered mills appeared by 1282 and spread through Italy and later Germany. The codex, with pages rather than a scroll, had been the standard for Christian and Muslim scribes since around 500 AD.
Movable type was not new either. Bi Sheng made clay characters in 11th-century Song China, Wang Zhen built wooden type on revolving tables around 1300, and Korea's Jikji of 1377 is the oldest surviving book printed with metal type. These methods never took over, partly because Chinese writing needs thousands of characters, making a complete set expensive. Gutenberg's Latin alphabet needed far fewer, though his type case still held an estimated 290 compartments for letters, ligatures and punctuation.
His own contributions were decisive. Drawing on metalworking skill, he cast type from an alloy of lead, tin and antimony, which proved durable, using a hand mould that produced identical letters quickly. He developed an oil-based ink that clung to metal better than water-based inks, and adapted the press so a flat platen pressed evenly without smearing, with a sliding bed for swapping sheets. A 1439 lawsuit against him is the first record of the project, which he had begun around 1436 with partners Andreas Dritzehn and Andreas Heilmann. The Mainz Psalter of 1453, with printed red and blue initials, was issued by his successors Johann Fust and Peter Schöffer.
Printing made texts cheaper and more plentiful, lifted literacy, fed the Reformation and the Scientific Revolution, and pushed books from Latin into standardised national languages. The wooden handpress then barely changed for over three centuries. Lord Stanhope's iron press arrived by 1800, The Times installed Friedrich Koenig's steam-driven machines in 1814, and Richard Hoe's rotary press of 1843 paved the way to millions of impressions a day.
