Rosine Bloch was a French operatic mezzo-soprano of Jewish descent who had a successful stage career in Europe between 1865 and 1891. She not only possessed a beautiful, warm, and lyrical voice but was also a remarkably beautiful woman physically. Although most of her career was spent performing at the Opéra in Paris, she also appeared in stages in Belgium, Monaco, and England.

The Théâtre Lyrique was one of four opera companies performing in Paris during the middle of the 19th century. The company was founded in 1847 as the Opéra-National by the French composer Adolphe Adam and renamed Théâtre Lyrique in 1852. It used four different theatres in succession, the Cirque Olympique, the Théâtre Historique, the Salle du Théâtre-Lyrique, and the Salle de l'Athénée, until it ceased operations in 1872.
