KAUDER, SAMUEL JUDAH BEN DAVID (Shmuel Loeb Kauders; 1766–1838), Bohemian rabbi. Born in *Bechyne, Bohemia, Kauder studied in the yeshivah of Eleazar Kallir in Kolin (where he made the acquaintance of Bezalel *Ranschburg, his lifelong friend and correspondent), and in Prague under Michael Bachrach. He settled in Prague where he officiated in the Altschul, and took an active part in the affairs of the ḥevra kaddisha and other communal institutions. In 1817 he was appointed to the rabbinate of the district of Budweis and Tabor with his seat in Kalladay. In 1834 he succeeded Samuel *Landau in the post of Oberjurist (av bet din; chief rabbi de facto, but not in name) of Prague. He was the last native Bohemian to hold this position, and was succeeded by the Galician maskil S.L. *Rapoport. His son Moses succeeded him as rabbi of the Altschul. His published works are: Olat Shemu'el, consisting of 111 responsa to Oraḥ Ḥayyim (Prague, 1823); Ahavat Emet (part 1, 1828), 18 homilies and sermons; and appended to it Pe'ullat Emet, seven halakhic discourses; and Zikkaron ba-Sefer (1937), a short commentary on tractate Megillah.
