German convert to Christianity and anti-Jewish writer; lived in the sixteenth century. He was the author of "Neue Judengeissel, eine Polemische Schrift Gegen Juden und Judenthum" (Fritzlar, 1589; Paderborn, 1600 and 1606; Ratisbon, 1601; Erfurt, 1605; with notes, Frankfort-on-the-Main and Leipsic, 1703; Hamburg, n.d.).
