Julius (Israel Lazarus) Mombach (1813 – February 1880) was a 19th-century English synagogue composer. Tunkel (2012) regards him as "the most important of the composers of synagogue music in the Anglo-Jewish tradition of the 19th Century" whilst Elton (2003) doesn't even restrict this assessment to England.
His compositions started from the traditional modes of synagogue music, but extended to include German and English folk song and contemporary classical themes. His style was influenced by Mendelssohn, and motifs from Elijah appear in a number of his pieces.
