Question: Who died first, Leoš Janáček or Gustave Charpentier?
Context: Destiny (also known as "Fate", Czech: "Osud" ) is an opera in three acts by Leoš Janáček to a Czech libretto by the composer and Fedora Bartošová.  Janáček began the work in 1903 and completed it in 1907.  The inspiration for the opera came from a visit by Janáček in the summer of 1903, after the death of his daughter Olga, to the spa at Luhačovice.  There, Janáček met Kamila Urválková, who had been the subject of an opera by Ludvík Čelanský, "Kamila", where she felt that Čelanský had falsely depicted her personality.  After learning that Janáček was a composer, Urválková persuaded Janáček to write another opera to counteract Čelanský's portrait of her. The Leoš Janáček International Competition in Brno (hereinafter referred to as MSLJ) (Czech: Mezinárodní soutěž Leoše Janáčka v Brně ) is a music competition held annually by the Faculty of Music of the Janáček Academy of Music and Performing Arts Brno.  The MSLJ was named after the famous composer Leoš Janáček. Káťa Kabanová (also known in various spellings including "Katia", "Katja", "Katya", and "Kabanowa") is an opera in three acts, with music by Leoš Janáček to a libretto by , based on "The Storm", a play by Alexander Ostrovsky.  The opera was also largely inspired by Janáček's love for Kamila Stösslová.  This is often considered his first "mature" opera, despite the fact that he was 67 when it was premiered.  "Káťa Kabanová" is a clear response to Janáček's feelings for Kamila, and the work is dedicated to her.  The first performance was at the National Theatre (Národní divadlo v Brně ) in Brno on 23 November 1921. Leoš Firkušný was a Czech musicologist.  He was born on July 16, 1905 in Napajedla (today's Czech Republic).  He was an older brother of the famous pianist Rudolf Firkušný.  He was an expert on Leoš Janáček and did much to bring his music to the listeners abroad.  He was one of the founders of the music festival Prague Spring.  He died on July 9, 1950 in Buenos Aires, Argentina. The Sinfonietta (subtitled “Military Sinfonietta” or “Sokol Festival”) is a very expressive and festive, late work for large orchestra (of which 25 are brass players) by the Czech composer Leoš Janáček.  It is dedicated “To the Czechoslovak Army” and Janáček said it was intended to express “contemporary free man, his spiritual beauty and joy, his strength, courage and determination to fight for victory.”  It started by Janáček listening to a brass band, becoming inspired to write some fanfares of his own.  When the organisers of the Sokol Gymnastic Festival approached him for a commission, he developed the material into the "Sinfonietta".  He later dropped the word "military".  The first performance was in Prague on 26 June 1926 under Václav Talich.  Typical performance duration is 20–25 minutes. Janáček is a crater on Mercury.  It has a diameter of 47 kilometers.

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. 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). Gustave Charpentier (] ; 25 June 1860 – 18 February 1956) was a French composer, best known for his opera "Louise". Leoš Janáček (] , baptised Leo Eugen Janáček; 3 July 1854 – 12 August 1928) was a Czech composer, musical theorist, folklorist, publicist and teacher.  He was inspired by Moravian and other Slavic folk music to create an original, modern musical style.
