The Brothers Fust
Johann and Jakob Fust were the sons of Claus Fust, a goldsmith and judge in Mainz in the 1440s, according to genealogical records from the Land of Hesse. Their father’s brothers were both priests at the church of the Blessed Virgin Mary and the church of Saint Clara in Mainz. These same Hessian records describe Johann Fust, Gutenberg’s partner, as a goldsmith who in 1448 was in partnership with a Frankfurt coinmaster (Münzmeister). Jakob, Johann’s brother, was a practicing goldsmith, a registered member of the Mainz goldsmiths’ guild who is listed in their records as having been killed in the civil war of 1462. His son and grandson continued after him as members of the goldsmiths’ guild. There are no contemporary images of either man, beyond fanciful renderings of Johann Fust with Gutenberg and Schoeffer.
