German Hebrew scholar. A former rabbi at Wetzlar, converted to Christianity (baptized first a Lutheran at Marburg in 1546, he became a Catholic soon after coming to Louvain), he taught Hebrew and 'Chaldaean' (Aramaic) at the University of Louvain from 1547 until 1551, when two Cologne aldermen, Constantin von Lyskirchen and Herman Suderman, could persuade him to come to their city as professor of Hebrew. He died at Cologne, 27 February 1577. Cf. F.
