10820 Offenbach           Discovered 1993 Aug. 18 by E. W. Elst at Caussols.
Jacob (Jacques) Offenbach (1819-1880) was a German-French composer who created the "opérette", or opéra bouffe, a type of comic opera that became very popular, especially in Paris. Orphée aux Enfers ("Orpheus in the Underworld", 1859) and La Belle Hélène (1864) are among his most famous operettas.
