Answer
The German-born composer Jacques Offenbach (1819–1880) was the leading exponent of operetta in the 19th century, and is credited with writing nearly 100 works in this genre. His most famous operettas include "The Tales of Hoffmann" (1881), "La Belle Hélène" (1864), and "Orphée aux enfers" (1858). Offenbach's operettas are characterized by their lively melodies, witty dialogue, and satirical humor.
