German Talmudist. His fame attracted many students to Neustadt, and his profound learning did much to revive the study of the original Rabbinic authorities. After the publication of the Code of Joseph Qaro the decisions of Isserlein in legal matters were added in notes to that code by Moses Isserles. His chief works were Terumath ha-Deshēn (354 decisions) and Pesaqim u-kethaḥim (267 decisions) largely on points of the marriage law.
