Question: Who lived longer, Gustave Charpentier or Léo Delibes?
Context: Emma Nevada (née Wixom) (7 February 1859 – 20 June 1940) was an American operatic soprano particularly known for her performances in operas by Bellini and Donizetti and the French composers Ambroise Thomas, Charles Gounod, and Léo Delibes.  Considered one of the finest coloratura sopranos of the late 19th and early 20th centuries, her most famous roles were Amina in "La sonnambula", and the title roles in "Lakmé", "Mignon", "Mireille", and "Lucia di Lammermoor. Jacques Charpentier (October 18, 1933 in Paris, France – June 15, 2017 in Lézignan-Corbières) was a French composer and organist.  He is unrelated to either of two other eminent French musicians with the same surname (Marc-Antoine Charpentier and Gustave Charpentier). This is list of operas and operettas written by the French composer Léo Delibes (1836–1891). Clément Philibert Léo Delibes (] ; 21 February 1836 – 16 January 1891) was a French composer of the Romantic era (1815–1910), who specialised in ballets, operas, and other works for the stage.  His most notable works include the ballets "Coppélia" (1870) and "Sylvia" (1876), as well as the operas "Le roi l'a dit" (1873) and "Lakmé" (1883). "La source (The Spring)" is a ballet in three acts/four scenes with a score composed by Léo Delibes and Ludwig Minkus (Minkus: Act I & Act III-Scene 2/Delibes: Act II & Act III-Scene 1) which was premiered in 1866 with choreography by Arthur Saint-Léon.  In 1878 in Vienna it was called "Naïla, die Quellenfee" ("Naïla, the Waternymph"). Julien, ou La vie du poète ("Julien, or The Poet’s Life") is a poème lyrique or opera by composer Gustave Charpentier.  The work is devised in a prologue and four acts and uses a French libretto by the composer.  "Julien" is a sequel to Charpentier's "Louise" (1900) and describes the artistic aspirations of Louise’s suitor Julien.  The opera premiered in Paris at the Opéra-Comique on 4 June 1913. Louise is an opera ("roman musical" ) in four acts by Gustave Charpentier to an original French libretto by the composer, with some contributions by Saint-Pol-Roux, a symbolist poet and inspiration of the surrealists. Du style galant au style méchant is an opera cycle written for radio by composer Germaine Tailleferre and librettist Denise Centore.  The cycle uses four short one act French language chamber operas, each one written to parody a different operatic form or style.  These operas are La fille d'opéra (a parody of Jean-Philippe Rameau), Le bel ambitieux (a parody of Giacomo Rossini), La pauvre Eugénie (a parody of Gustave Charpentier), and Monsieur Petit Pois achète un château (a parody of Jacques Offenbach).  The cycle had its world premiere on December 28, 1955 in a performance by the Radiodiffusion-Télévision Française. Balanchine's had previously made a "pas de deux" to music from Léo Delibes' "Sylvia" in 1950; he expanded this into a divertissement in 1965.  The final version uses music from Delibes' ballets "La source" and "Sylvia" and choreography from the earlier pas de deux and divertissement. Gustave Charpentier (] ; 25 June 1860 – 18 February 1956) was a French composer, best known for his opera "Louise".
