After his matriculation he studied philology and philosophy at Berlin, where he also continued his Talmudic studies. In 1860 he received the degree of Ph.D. from the University of Leipsic, his thesis being "Philosophischkritische Abhandlung über den Schlussvers des Zweiten Buchs der Psalmen."
After officiating for five years as preacher and religious teacher at Waren, Mecklenburg, he went in 1867 to Bielitz, Austrian Silesia, as director of the Jewish communal school there. Five years later he became preacher at Oels, where he officiated until 1882. In that year he was appointed rabbi at Bonn, where he remained until his death.
