Philipp Melanchthon was Luther's most important companion and much more than that. The quiet and stuttering little Greek professor was the true communicator of the Reformation: he conducted political and theological negotiations, traveled incessantly, wrote countless letters, and turned the Reformation into an educational movement. Heinz Scheible has extensively revised and expanded his highly acclaimed biography of the great humanist for this new edition. When Melanchthon moved from Tübingen to Wittenberg in 1518 at the age of 21, the 14 years older Luther was thrilled by the "wonderful man, in whom almost everything is superhuman." A close friendship quickly developed between the sensitive humanist and the boisterous theologian, which was immortalized in numerous dual portraits. However, Melanchthon's independent work as a reformer should not be overlooked.
