Gutenberg or Johannes Gensfleisch zur Laden zum Gutenberg was a real-life person on Earth who's seen as the grandfather of modern printing technology and is one of Myne's greatest idols. She later uses this prestigeous name as a title for those who made noteworthy contributions to the birth and spread of the printing industry in her new world.
As the first person bestowed with the title, the smith Johann ended up with 'Gutenberg' as a sort of nickname within his own workshop. A fact he is not at all happy about.
