Two Nuremberg merchants, Sebald Schreyer (1446–1503) and his son-in-law, Sebastian Kammermeister (1446–1520), commissioned the Latin version of the chronicle. They also commissioned George Alt (1450–1510), a scribe at the Nuremberg treasury, to translate the work into German. Both Latin and German editions were printed by Anton Koberger, in Nuremberg. Contracts were recorded by scribes, bound into volumes, and deposited in the Nuremberg City Archives. The first contract from December, 1491, established the relationship between the illustrators and the patrons. The painters, Wolgemut and Pleydenwurff, were to provide the layout of the chronicle, to oversee the production of the woodcuts, and to guard the designs against piracy. The patrons agreed to advance 1000 "gulden" for paper, printing costs, and the distribution and sale of the book. A second contract, between the patrons and the printer, was executed in March 1492. It stipulated conditions for acquiring the paper and managing the printing. The blocks and the archetype were to be returned to the patrons once the printing was completed.
