Fust and Schoffer
The twin shields of Fust and Schoffer is the earliest know printer's device. It first appeared on their Biblia Latina of 1462. Johann Fust (fl. 1450-1466), a lawyer in Mainz, Germany, is remembered as the financial backer of Johann Gutenberg, the inventor of printing from moveable type. In the middle of the fifteenth century, he advanced Gutenberg the funds that enabled him to develop his new invention. ABout 1457, Fust entered into partnership with Peter Schoffer (fl. 1449-1502), a calligrapher. Together, they issued the Mainz Psalter, the first successful attempt at color printing.
