• noun Johannes Gutenberg (1399?–1468), a German printer, and the inventor of printing as we know it. Gutenberg was the man who saw that separate pieces of metal type, one for each letter, could be duplicated by being cast from matrices, and that these separate pieces of type could then be put together in rows, clamped into chases, inked and multiple impressions taken from them. This method of typesetting did not materially change until the phototypesetting machines of the 1960s.
