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.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
