Oecolampadius, Joannes, Latinized Greek for H�ssgen or Hausschein 1482-1531
German clergyman and scholar

Born in Weinsberg, Swabia, he studied at Heidelberg. He became tutor to the sons of the elector palatine, and subsequently preacher at Weinsberg (1510) and Basle (1515), where Desiderius Erasmus employed him on his Greek New Testament. In 1520 he entered a monastery at Attom�nster, but under Martin Luther's influence became a reformer at Basle in 1522, where he was Professor of Theology. He gradually adopted the views of Huldreich Zwingli on the Lord's Supper, disputed with Luther at Marburg in 1529, and wrote treatises.
