Antoine Mariotte (22 December 1875 – 30 November 1944) was a French composer, conductor and music administrator.
Mariotte was born in Avignon (Vaucluse) in 1875. After studies at the School of Saint-Michel in Saint-Étienne, he entered naval school aged 15.
In 1894, while serving on the frigate Iphigénie, he wrote to a friend that he missed music and if he had the means he would go to the Conservatoire de Paris. While still split between the life of a sailor and musician, he worked away on harmony. He took part in campaigns on board the Forfait in the South China Sea, then on the Vinh-Long, where he witnessed the closing stages of the Sino-Japanese War. He brought back sketches that became the suite Kakémonos, initially written for the piano, but later orchestrated and performed at the Concerts Poulet on 29 January 1923 (Panorama, Geishas, Temple au Crépuscule, Fête).
In the Far East he read the Oscar Wilde play Salome, and decided to set it to music. On return to Europe, he sailed on the Marceau then the Magenta where finally, thanks to Admiral Gervais, he had a piano. On six months leave he followed a course at the Conservatoire by Charles-Marie Widor. After prolonging his absence, he resigned from the navy in 1897. He entered the Schola Cantorum where he was taught by Vincent d'Indy, who found him work as a pianist at the home of the comte de Chambrun, to whom he played each day for precisely 60 minutes, in particular the 32 sonatas of Beethoven in chronological order.
Due to his mother's health, he went back to Saint-Étienne and taught piano and became an organist, also directing the symphonic society; he also wrote an operetta Armande. Appointed professor of piano at the Lyon Conservatoire, he completed the score of Salomé, believing himself to have .permission from Wilde's estate and the publisher Methuen. In fact, having obtained the agreement to use the play, Richard Strauss had in turn asked his publisher Fürstner to acquire the rights. Wilde's particularly complicated estate led to a court case that favoured the rights of Fürstner. Mariotte learnt that Fürstner would oppose the production of a "Salomé française" and after going to Berlin, he obtained permission to have his piece staged, on condition that 40% royalties went to Richard Strauss and 10% to Fürstner, with all scores to be sent after the run to Fürstner to be destroyed. Romain Rolland, having read an article by Mariotte in the Revue internationale de musique, helped him to obtain a more generous settlement from Strauss. On 30 October 1908, Mariotte's opera was produced at the Grand-Théâtre de Lyon with success (de Wailly in the title role), and staged in 1910 at the Gaîté-Lyrique in Paris, while Strauss's Salomé was on at the Opéra. After having been performed at Nancy, Le Havre, Marseille, Geneva, and Prague, Mariotte's Salomé was seen at the Opéra on 1 July 1919 with Lucienne Bréval. In November 2005 the Opera National de Montpellier juxtaposed the Strauss and Mariotte operas. Mariotte's Salomé was produced by Wexford Festival Opera in October 2014.
