John Oecolampadius

Johannes Oecolampadius (Œcolampadius, in German also Oekolampadius, Oekolampad; 1482 – 24 November 1531) was a German Protestant reformer in the Reformed tradition from the Electoral Palatinate. He was the leader of the Protestant faction in the Baden Disputation of 1526, and he was one of the founders of Protestant theology, engaging in disputes with Erasmus, Zwingli, Luther and Martin Bucer. He eventually adopted Zwingli's view on the eucharist dispute (against Luther).

His German surname was Hussgen (or Heussgen, Huszgen), which he etymologized to Hausschein ("house-shine") and graecicized (as was the custom at the time) to Oecolampadius (from oiko-, "house," and lampad-, "torch, lamp").

He was born in Weinsberg, then part of the Electorate of the Palatinate. He attended school at Weinsberg and Heilbronn, and then, intending to study law, he went to Bologna, but soon returned to Heidelberg and took up theology. Enthusiastic about the new learning, he passed from the study of Greek to that of Hebrew, taking his bachelor's degree in 1503. He became cathedral preacher at Basel in 1515, serving under Christoph von Utenheim, the humanist bishop of Basel. In Basel, Oecolampadius became an editorial assistant and Hebrew consultant to Erasmus' first edition of the Greek New Testament, and wrote that edition's epilogue in praise of his master.
