Moses ben Israel ha-Levi Landau (1788-1852) was a printer, publisher, and lexicographer. Born in Prague, he was a grandson of R. Ezekiel Landau, and was imbued with the traditional atmosphere of that rabbinical family. At the same time he devoted himself to secular studies, especially German studies. He established a Hebrew printing press in Prague which, for more than two decades, published sacred literature along with some contemporary Hebrew works. From 1831, he was head of theJewish community of Prague and was instrumental in bringing R. Solomon Judah Rapoport there to serve as rabbi. The best known of Landau’s works is Ha-Arukh u-Mussaf ha-Arukh im Ma’aneh ha-Lashon, the Talmudic dictionary of R. Nathan ben Jehiel with German transkatuion.
