Julie Dorus-Gras (7 September 1805 – 6 February 1896) was a Belgian operatic soprano. Both give the singer's nationality as Belgian. Forbes in Sadie (1992) and Kuhn  both describe her as a "South Netherlands soprano"; Spire Pitou (p. 380) does not specify nationality. Forbes (both in 1992 and 2001), Kuhn, and Pitou give the singer's date of birth as 7 September 1805, while Warrack gives 9 September 1805, which is likely an error.
Early life and training
She was born Julie-Aimée-Josèphe Van Steenkiste, the daughter of an ex-soldier who was the leader of the theatre orchestra in her native city Valenciennes. She first studied with her father and began performing as a child, eventually becoming so well known as a vocalist that she received a municipal scholarship which enabled her to continue her studies in Paris. She was admitted to the Paris Conservatoire in 1821 and studied singing in the class conducted by Blangini and Henri. Later she received additional vocal training from Bordogni and Paer.
To begin her career she made a concert tour which took her to Brussels. Her concert was so successful, that Count de Liederkerke offered her a contract to sing operatic roles. Although she had not previously considered performing in dramatic works, she agreed, as Cassel would coach her for six months to prepare her for singing and acting on stage. She made her debut in 1825 at the Théâtre de la Monnaie in Brussels. In 1829 she performed Elvire in the first Brussels performance of Auber's La muette de Portici and repeated the role in the notorious performance of 25 August 1830 which precipitated the Belgian Revolution.
The increasing political unrest in Belgium caused her to decide to return to Paris. She was engaged by the Paris Opera and first performed there as the Countess in Rossini's Le comte Ory on 9 November 1830. Later she created roles in the world premieres of several notable operas, including Alice in Giacomo Meyerbeer's Robert le diable on 21 November 1831, Oscar in Daniel Auber's Gustave III, Pauline in Gaetano Donizetti's Les Martyrs (the French version of Poliuto), Princess Eudoxie in Fromental Halévy's La Juive, Ginevra in Halévy's Guido et Ginevra, Marguerite de Valois in Meyerbeer's Les Huguenots, and Teresa in Berlioz's Benvenuto Cellini.
