Talk to Johannes Gutenberg
The goldsmith who developed printing with movable type
c.1400–1468Germany
Goldsmith and entrepreneur of Mainz who developed printing with movable metal type in Europe around 1450, including a hand-casting mould for type, an oil-based ink and a press adapted from the wine press. The 42-line Bible printed in Mainz in the mid-1450s is traditionally regarded as the first major book printed in Europe from movable type. He lost his workshop in a lawsuit with his financier Johann Fust and died with little recognition.

Questions about Gutenberg
- Who was Johannes Gutenberg?
- Goldsmith and entrepreneur of Mainz who developed printing with movable metal type in Europe around 1450, including a hand-casting mould for type, an oil-based ink and a press adapted from the wine press. The 42-line Bible printed in Mainz in the mid-1450s is traditionally regarded as the first major book printed in Europe from movable type.

- Can you talk to Gutenberg with AI?
- Yes, in the Yuga app for iPhone and Android. You talk out loud with an AI recreation of Gutenberg, set in Mainz, 1454. It draws on their own writing and well-sourced accounts of their life, and it can still get things wrong, so check anything important against the sources.
- Is that really Gutenberg's voice?
- No. No recording of their voice survives. Yuga's voice is designed from how people at the time described it, and every call is labelled an AI recreation.
- What did Gutenberg say about the financing dispute with Johann Fust?
- In the lawsuit of 1455, Fust claimed the return of 1,600 guilders with interest, while Gutenberg argued that part of the money had been invested in the workshop and tools rather than owed as a loan; the court found largely for Fust. Source: Helmasperger notarial instrument, 6 November 1455.
- What did Gutenberg say about the Dritzehn partnership in Strasbourg?
- Records of the 1439 lawsuit show that Gutenberg had taught Andreas Dritzehn and others a secret craft involving a press and lead, and that he wished the equipment dismantled after Dritzehn's death to protect it. Source: Strasbourg lawsuit records, December 1439.
- What did Gutenberg say about Printing sacred texts and the aims of the Mainz press?
- He produced a large Latin Bible of 42 lines per page, intended for churches and religious houses and priced as a luxury work; the surviving evidence is the books themselves rather than a statement by him. Source: Gutenberg Bible, c.1454–1455; letter by Enea Silvio Piccolomini, 1455, describing the Bible seen at Frankfurt.
How Gutenberg talks
Concrete and technical. He describes things in terms of metal, mould, ink, paper and pressure, and answers questions about the 'secret art' guardedly. Plain and unadorned, wary about naming partners or costs. Modest about himself, with occasional pride in precision.
