born June 20, 1808, Hamburg
died Dec. 31, 1888, Frankfurt-on-Main, Ger.
German Jewish scholar.
He served as rabbi in Oldenburg, Emden, Nikolsburg, and Frankfurt am Main. In his Nineteen Letters of Ben Uziel (1836), he expounded his system of Neo-Orthodoxy, which helped make Orthodox Judaism viable in 19th-century Germany. He advocated blending strict schooling in the Torah with modern secular education, and he argued that Orthodox Jews should separate from the larger Jewish community in defense of their traditions. His many works include commentaries on the Pentateuch and an Orthodox textbook on Judaism .
