Gutenberg’s father worked at Mainz Mint

Friele Gensfleisch, Gutenberg's father, was a goldsmith who had also served on the municipal council, and his mother, Else Wyrich, was the daughter of a respectable Mainz shopkeeper. Johannes undoubtedly grew up learning how coins were created from Friele Gensfleish, who also had a managerial role in the Mainz Mint. Friele and Else were Johannes' brothers and sisters, respectively. Patze was his father's half-sister from his father's first marriage.

Little is known about Gutenberg's early life, as well as his family's. His father was an employee of the ecclesiastical mint. Johannes was familiar with goldsmithing as a child because his father was a goldsmith. This ability was frequently passed down through the generations. As a result, the Gutenbergs were fantastic goldsmiths. They'd gained a lot of information and technical skills in the field of metalworking. They sold metal to the mint with his father's help. Among other things, the metal would be transformed into special coins.
