WEISZ, MAX (1872–1931), Hungarian rabbi and scholar. Weisz was born in Budapest, where he received rabbinic ordination at the Landesrabbinerschule. He became a rabbi in Pest and professor at the Landesrabbinerschule. A pupil of David *Kaufmann, Weisz did research in Jewish history, history of civilization, and literature. When the Kaufmann library became the property of the Hungarian Academy of Sciences, Weisz was named its archivist.
He prepared the Katalog der hebraeischen Handschriften und Buecher in der Bibliothek des Prof. Dr. David Kaufmann (1906), and edited, from this collection, the ritual book Seder Troyes by Menahem ben Joseph (in: Sefer Yovel … Moses Aryeh Bloch (1905), 97–137, Heb. pt., and in the same year also separately), and an Italian-Jewish minhag book from the 13th century (in Ha-Ẓofeh, le-Ḥokhmat Yisrael, 13 (1929), 217–45). As a result of his studies of the Kaufmann genizah, he published letters he had discovered, the liturgic compositions of a paytan he called Samuel (Seridim me-ha-Genizah, 1924), geonic texts (in: Ve-Zot li-Yhudah … li-Khevod … Yehuda Aryeh Blau (1926), 159–63), and Festschrift … der … Landesrabbinerschule (Heb. pt., (1927), 77–97).
