1482-1531. German Reformer. A native of the Palatinate whose original name was Hussgen or Hauschein, he became the leading Protestant Reformer of Basle. A brilliant philologist in Latin, Greek, and Hebrew, he began his university studies in law at Bologna, but transferred to theology at Heidelberg. Employed for a time as a tutor, he later secured a prebend at Weinberg (1503-12). Further studies at Tübingen and Stuttgart led to his contact with Reuchlin* and Melanchthon.* In 1515 he was called as minister to Basle, where he met Erasmus* and assisted him in the publication of the Greek NT. Later (1518) Oecolampadius became a pastor at Augsburg, where he was deeply affected by Luther's teachings. Then the pressure of his work caused him to enter a monastery (1520), only to withdraw after a short while.
