Jewish composer; born at Hohenens, in Vorarlberg. He studied composition under Seyfried in Vienna. Lippman in Switzerland was his first teacher, and Sulzer accompanied him through France before returning to his native town, where he became cantor of the Synagogue in 1820. Five years later he went to Vienna as chief cantor, and organized a splendid choir. He was also singing teacher at the Conservatory from 1844 to 1847. He did great service for Jewish music by arranging the old melodies in modern rhythm and harmony, and was honored not only by a silver laurel from his fellow musicians in Vienna, various medals and the Order of Franz Joseph in 1868, but by the friendship of such artists as Meyerbeer, Liszt, Paganini, Schubert and Schumann. He published a collection of hymns, Schir Zion, and another of songs, called Dudaim, besides corncomposing psalms and songs.
