R. Israel Moses ben Eliezer Hazzan (1808-62) rabbi, writer and polemicist against reform. He studied in the yeshivah of his grandfather Joseph Raphael Hazzan, and in 1842, was appointed a member of the bet din in Jerusalem. In 1844, R. Hazan went to London as an emissary of the Jerusalem community. While there he wrote pamphlets against the reform movement and joined a group organized for that purpose. He subsequently went to Rome, where he was appointed Chief Rabbi (1847–54). Although a strong champion of Orthodoxy, R. Hazan protested against such practices of the Jews of Rome as washing corpses with warm water, and not allowing a clock in the yard of the synagogue. He next served as rabbi in Corfu for five years and after as rabbi and av bet din in Alexandria, until 1862. In addition to Kedushat Yom Tov, R. Hazzan wrote Nahalah le-Yisrael (Vienna, 1851), on deciding laws of inheritance according to the Torah; She’-erit ha-Nahalah (Alexandria, 1862), concerning a dispute between a merchant and two emissaries of Erez Israel. Nezah Yisrael, which has remained in manuscript, is an attack on the Vikku’ah al Hokhmat ha-Kabbalah of S. D. Luzzatto; Iyyei ha-Yam, in two parts (pt. 1 Leghorn, 1869; pt. 2 still in manuscript), on the responsa of the geonim, and Kerakh shel Romi (Leghorn, 1876), responsa. Still in manuscript are Hoker Lev, responsa, and Yismah Lev, sermons preached in Jerusalem and during his activity as an emissary.
