Dutch rabbi; born at Muiden (near Amsterdam) July 24, 1863; studied at the theological seminary and the University of Amsterdam (B.A. 1884). He was appointed rabbi of the congregation at Amsterdam on July 5, 1888. Onderwijzer has published a translation of the Pentateuch and Rashi's notes (Amsterdam, 1895). On Oct. 29, 1895, he founded the Jewish labor-union Bezaleel, of which he is the honorary president. Bezaleel cares especially for the religious needs of its members (200 in 1904), who are for the greater part diamond-workers. With the other congregational unions of Amsterdam, Patrimonium and St. Eduardus, it supports the Algemeene Nederlandsche Diamantbewerkers Bond, though Bezaleel is entirely independent of that organization.
