Johann Emerich was a printer and typographer from Udenheim, near Speyer, in the Rhineland in the Holy Roman Empire. He was active as a book printer and typographer in Venice from 1487, when he collaborated with Johannes Hamman of Landau in the printing of a breviary and a missal, until about 1499, when he spent almost six months on the printing of an illustrated Graduale secundum morem sancte Romane Ecclesie for the Florentine publisher Lucantonio Giunti. Emerich is thought to have died at about this time. His fonts and equipment passed to Giunti and enabled him to establish his own printing workshops.
