Pierre Gaveaux (9 October 1761 – 5 February 1825) was a French operatic tenor and composer, notable for creating the role of Jason in Cherubini's Médée and for composing Leonore ou l'amour conjugal, the first operatic version of the story that later found fame as Fidelio.
Gaveaux was born in Béziers and sang in the cathedral choir there from the age of seven. Although intending to enter the priesthood, he also took lessons in composition. He next became first tenor at the Basilica of Saint-Seurin in Bordeaux, studying with Franz Beck, and subsequently decided to follow a career in music, becoming a conductor at the Grand Théâtre de Bordeaux as well as continuing to sing.
After a period in Montpellier, he moved to Paris where, on 26 January 1789, he took part in a performance of Giacomo Tritto's Le Avventure Amorose, which marked the inauguration of the Théâtre de Monsieur company in the Salle des Machines at the Tuileries Palace.
He subsequently performed with the company in operas such as Paisiello's L’Infante de Zamora (in 1789), and on 18 July 1791 he sang the role of Floresky in the première of Cherubini's Lodoïska. When the company moved to the Théâtre Feydeau, he was involved in a "folly in verse" called Le club des bonnes gens which was banned by the censor for being unpatriotic.
He was active during the revolutionary period, composing in 1792 a hymn to the Supreme Being. On 19 January 1795, his famous Jacobin song Le Réveil du peuple (The Awakening of the People), to words by Jean-Marie Souriguière de Saint-Marc, was first performed. Notwithstanding the banning of the song on 8 January 1796 by the Directoire, he continued his career in opera, appearing in François Devienne's Les visitandines, and creating the role of Jason in Cherubini's Médée on 13 March 1797.
