Pierre Beaumarchais
In 1786, Wolfgang Amadeus Mozart composed an opera, "Le Nozze di Figaro", based on "The Marriage of Figaro", with a libretto by Lorenzo Da Ponte based on the play. Several composers including Paisiello in 1782 wrote operas based on "The Barber of Seville". Rossini's 1816 version is his most successful work and still often performed. In 1966, Darius Milhaud composed an opera, "La mère coupable", based on "The Guilty Mother".
Robert de Flers
In 1901 de Flers married Geneviève Sardou, the daughter of Victorien Sardou. He continued to be active writing librettos. His third opera libretto, "Les travaux d'Hercule" (1901), marked his first collaboration with fellow playwright Gaston Arman de Caillavet and composer Claude Terrasse. Most of his remaining librettos were written with Caillavet, often for Terrasse who was their most frequent musical collaborator. Other composers for which the two men wrote librettos include André Messager, and Gabriel Pierné. The two men also wrote a French translation of Franz Lehár's "The Merry Widow" in 1905 which was used throughout France during the first half of the 20th century. Their last opera collaboration was for Alfred Bruneau's 1923 opera "Le jardin du paradis". De Flers also wrote the librettos for Reynaldo Hahn's "Ciboulette" (1923) with playwright Francis de Croisset, and Joseph Szulc's "Le petit choc" (1923).
