Balthasar Hubmaier
Bathasar Hubmaier was a violent Antisemitic ex catholic alongside Erasmus and Zwingli who rejected his colleagues and repented by adopting Anabaptist pacifism in 1525. After his conversion he moved to Moravia where he became a defender of the Jewish Sabbath through his Silesian students Oswald Glait and Andreas Fischer organizing the Moravian Anabaptists from the remnant of utraquist Bohemian reformers.
