In what trade was Gutenberg?

Johannes Gutenberg (c. 1400–1468) was a goldsmith, inventor, printer, and publisher who introduced printing to Europe. He is best known for his invention of the printing press, which revolutionised European printing and made possible the mass production of books. Gutenberg's other inventions include a movable type printing system, an oil-based ink, and the use of a casting mould for the type. These inventions laid the foundation for the modern printing industry and changed the way information was disseminated in the world.
