Philipp Melanchthon [Melancthon] (1497-1560) humanist scholar, university professor, and Reformation theologian, was called the "Teacher of Germany" because of his efforts to improve educational standards. A tireless writer, a few of his more famous works include: Loci Communes Theologici (first issued in 1521 but often revised as his thinking matured), the Augsburg Confession (1530), and Commentary on Romans (1540).
