Johann Tetzel, German preacher (b. 1465)
Johann Tetzel (c. 1465 – 11 August 1519) was a German Dominican friar and preacher. He was appointed Inquisitor for Poland and Saxony, later becoming the Grand Commissioner for indulgences in Germany. Tetzel was known for granting indulgences on behalf of the Catholic Church in exchange for money, which are claimed to allow a remission of temporal punishment due to sin, the guilt of which has been forgiven, a position heavily challenged by Martin Luther. This contributed to the Reformation. The main usage of the indulgences sold by Johann Tetzel was to help fund and build the new St. Peter's Basilica in Rome.
