German dramatic soprano, who from 1825 to 1835 was a member of German Opera companies in Vienna, Berlin and Munich. The Queen of Bavaria was her patroness and after a period of study with Grassini and Ronconi in Italy, the young singer appeared in Italian Opera in Munich, until 1827, devoting herself afterward to singing roles in German Opera. She sang in Weigl's Schweizer familie in Berlin and was especially successful in Don Giovanni and Euryanthe, and was unrivaled in the interpretation of the leading soprano roles in Fidelio, Iphigenia, Spontini's Vestalin and the operas of Weber, Gluck, Beethoven and Cimarosa. In 1832 she married an artist named Waagen, and three years later, owing to her ill health, retired from the operatic stage. Although she ranked high among German singers her career lasted only ten years. Her voice had great power and her acting was greatly admired.
