Born in Frankfurt am Main, Deinet studied under Elise Seebach before making her professional opera debut at the opera house in Frankfurt as Gabriele in Conradin Kreutzer's "Das Nachtlager in Granada" in 1861. Later that year she became a principal artist at the Hessisches Staatstheater Wiesbaden where she had her first big successes during the 1861–1862 season. In 1862–1863 she sang at the Bremen Theater.
In 1863, Deinet was appointed to the Bavarian State Opera where she remained until her retirement from the stage fifteen years later. Her first assignments at the house were Isabella in Giacomo Meyerbeer's "Robert le diable", the Queen of the Night in Wolfgang Amadeus Mozart's "The Magic Flute", and Leonora in Giuseppe Verdi's "Il trovatore". On 10 June 1865 she created the role of Brangäne in Wagner's "Tristan und Isolde" under the baton of Hans von Bülow. She also created the role of Helmwige (one of the Valkyries) in Richard Wagner's "Die Walküre" on 26 June 1869.
While performing in Munich, Deinet met actor Ernst von Possart (1841–1921) and began a romantic relationship with him in the mid-1860s.
