German printer and composer. In 1518 he became cantor at the Thomasschule in Leipzig, but as one of Luther's first followers he abandoned this post in 1520, and in 1523 became a schoolmaster in Wittenberg. He started a printing business there in 1525, and published many important collections of early Lutheran music including works by all the leading composers of the day who had Protestant sympathies. These publications contained simple congregational psalm settings and sacred songs, and also the more elaborate Masses and motets still used in Lutheran worship.
