Opera Singer. A soprano, she is remembered for reviving the operas of Christoph Willibald Gluck and for having sung the role of Leonore in all three versions of Beethoven's "Fidelio". Born Pauline Anna Milder, she was raised in what was then called Constantinople and later in Bucharest, Romania, as the child of servants to the Austrian diplomatic corps learning multiple languages from an early age. Settling in Vienna at age 10, she began adding German to her tongues and had her first music lessons with, among others, Maestro Antonio Salieri. Anna made her 1803 debut as Juno in Sussmayr's "Der Spiegel von Arkadien" and in 1805 performed the first version of Beethoven's "Fidelio", a work with which the great composer was never really satisfied. In 1806 Luigi Cherubini composed "Faniska" for her and that same year she sang Beethoven's first revision of his only opera; in 1809 she declined Napoleon's invitation to sing in France and in 1810 married jeweler Peter Hauptmann (after which she was sometimes billed as Milder-Hauptmann), an unpleasant man whose interpersonal difficulties with managers and composers probably hurt her career. Her 1812 success in Gluck's "Iphigenie en Tauride" led to renewed interest in that composer's works in both Vienna and Berlin; Anna sang Cherubini's "Medee" as well as the final version of "Fidelio" in 1814 and in 1815 relocated to Berlin where she remained for 14 years. Anna was to reign as prima donna of the Court Opera, called upon for several world premiere's of now forgotten pieces, and singing a number of songs written for her by Franz Schubert. She appeared in Mendelssohn's 1829 revival of Bach's "St. Matthew Passion", but quarrels soon took her away from Berlin; Anna toured Russia and the Scandanavian countries and gave her final performances in 1836.
