Isaac Eberst

Isaac Eberst (26 October 1779 – 26 April 1850), known after 1808 as Isaac Offenbach, was a German chazzan, composer, and writer. He served for decades as the cantor of the Cologne synagogue and is best known today as the father of the composer Jacques Offenbach.

Early life and background​

Born Isaac Juda Eberst in Offenbach near Frankfurt, he was the son of Judah and Terz Eberst. Orphaned young, he likely grew up within the local Jewish community and learned cantorial practice with traveling cantors. In 1799 he received a travel pass stating his intent “to make music in synagogues,” beginning a period as a wandering musician and acquiring the nickname "der Offenbacher".

Following the 1808 Napoleonic decree requiring fixed family names, he adopted Offenbach as his official surname.

Career​

In 1802 Eberst settled in Deutz, across the Rhine from Cologne, where he earned his living both as a synagogue musician and as a violinist in dance saloons and taverns. There he continued composing liturgical music and married Marianne (Miriam) Rindskopf.

The couple later moved to Cologne, where a new Jewish community was emerging (following an expulsion in the 15th century). Offenbach supported himself as a teacher of violin, flute, guitar, and singing. Around 1820 he began performing regularly with his tenor voice in synagogue services, and after several years became the community’s permanent chazzan, a post he held for nearly three decades until his death.

In November 1833 Offenbach traveled to Paris with his sons Jacques and Jules, auditioning twice for the Rue de Nazareth Synagogue. Jacques entered the Conservatoire as a cello student and Jules received violin instruction; both served for six months as musical directors of the synagogue choir before the family returned to Cologne.

Publications and compositions​

Offenbach was a prolific composer of synagogue music and a versatile writer, editor, and translator. His publications included a Haggada with German translation and appended melodies (1838) and a Hebrew–German youth prayer book (1839). He also wrote secular music, including guitar works such as Douze sonatines pour la guitare, and composed Purim-related pieces, including Esther, Queen of Persia (1833). In later years he published satirical Purim poems criticizing contemporary religious trends, including a “Humorous Poem of a Polish Mocher Seforim” (1848) and a “Humorous Poem of an Antiques Salesman” (1849).

Legacy and manuscripts​

A substantial portion of Offenbach’s musical manuscripts survive, including roughly twenty folders of cantorial compositions and transcriptions of traditional synagogue melodies. His granddaughters donated materials to the Jewish Institute of Religion in New York, the Birnbaum Collection at Hebrew Union College in Cincinnati, and the Jewish National and University Library in Jerusalem. The manuscripts offer a rare, detailed picture of Ashkenazi cantorial practice during the early 19th century.
