Wildly popular in his day, Jules Massenet (1842–1912) was noted for his operas, songs, and oratorios. His style lost popularity in the early 20th century, with only Manon (1884) and, in recent decades, Werther and Thaïs (1894) maintaining a place in the repertory. Three dramatists collaborated on the Werther libretto: Édouard Blau (1836–1906), Paul Milliet (1855–1924), and Georges Hartmann (1843–1900). Johann Wolfgang von Goethe (1749–1832) is the preeminent figure of German literature and the author of Faust. He was also a well-regarded authority on philosophy, art, and especially music.
