OSIANDER, ANDREAS° (1498?–1552), German theologian, religious reformer, and *Hebraist. Born in Gunzenhausen (Franconia), Osiander was ordained a priest in 1520, but shortly thereafter converted to Protestantism, becoming one of the most influential reformers of the time. He was a Hebrew tutor at Nuremberg and continued his studies with a Jew, Woelfflein of Schnaittach, who was given the extraordinary privilege of visiting Nuremberg for that purpose. In the wake of the *Pezinok blood libel of 1529, Osiander published an anonymous refutation of the ritual murder charge, which led to a literary dispute with Johannes Eck. Although Osiander was himself a Lutheran theologian, in a private letter to Elijah *Levita he vehemently denounced Martin *Luther's anti-Jewish Vom Schem Hamphoras (1544). In 1548 Osiander left Nuremberg and was made professor of Hebrew at the then newly founded University of Koenigsberg, where he died a few years later.
