Franziska Cornet (23 January 1808 – 7 August 1870) was a German operatic soprano and singing teacher.
She was trained in singing by her father, and in March 1823 she appeared as a singer for the first time, as Thisbe in the opera Cinderella.
She soon afterwards appeared as Princess Lydia in La neige by Daniel Auber, the Countess in Mozart's The Marriage of Figaro and Olivier in Jean de Paris by Boieldieu.
[1] Her roles included Isabella in Robert le diable by Meyerbeer and Leonora in Fidelio by Beethoven.
[1][2][3] Her biographer in Allgemeine Deutsche Biographie (1876) wrote: "With the great purity of her soprano voice, and the particularly good training of her coloraturo, as well as her lively, adroit acting, Mrs Cornet belonged among the most important singers.
