Désirée Artôt (21 July 1835 – 3 April 1907) was a Belgian soprano (initially a mezzo-soprano), who was famed in German and Italian opera and sang mainly in Germany. In 1868 she was engaged, briefly, to Pyotr Ilyich Tchaikovsky, who may have coded her name into works such as his First Piano Concerto and the Romeo and Juliet Fantasy-Overture. After her 1869 marriage to the Spanish baritone Mariano Padilla y Ramos, she was known as Désirée Artôt de Padilla or Désirée Artôt-Padilla.
Marguerite-Joséphine-Désirée Montagney Artôt was the daughter of Jean Désiré Montagney Artôt, a horn player at La Monnaie in Brussels and professor at the Brussels Conservatory. Her uncle was the violinist Alexandre Artôt (1815–1845). He had been born Alexandre Joseph (or Joseph-Alexandre) Montagney, but adopted the surname Artôt professionally, and the rest of his family followed suit. Another uncle was the Belgian portrait painter Charles Baugniet (1814–1886).
She studied with Pauline Viardot and Francesco Lamperti in London and Paris. She appeared in concerts in Belgium, the Netherlands and on 19 June 1857 at a State Concert in England. Giacomo Meyerbeer engaged her for the Paris Opéra, where she made her debut on 5 February 1858 as Fidès in his Le prophète, to great success. She also sang the title role in a condensed version of Gounod’s Sapho. Hector Berlioz and others praised her singing in the Journal des Débats on 17 February. However, she abandoned the French repertoire and went to sing in Italy in 1859. She also sang in Berlin that year, at the opening of the Victoria Theatre with Lorini’s Italian company. She was highly successful in The Barber of Seville, La Cenerentola, Il trovatore and other roles there.
