Mathilde Wildauer (7 February 1820 – 23 December 1878) was an Austrian actress, later an operatic soprano, taking leading roles at the Theater am Kärntnertor in Vienna.
[1] She went on to appear in comedies by Kotzebue, August Wilhelm Iffland, Roderich Benedix and Eduard von Bauernfeld, and became well liked by the public.
[1][2] As an operatic soprano she first appeared in 1845 at the Theater in der Josefstadt, in operas including La fille du régiment by Gaetano Donizetti as Marie.
During this period she continued in acting roles at the Burgtheater, where in 1848 she created the role of Nandl in the original production of the Singspiel Das Versprechen hinterm Herd (The promise behind the hearth) by Alexander Baumann [de]; this was regarded as one of her greatest successes.
Roles included Susanna in Wolfgang Amadeus Mozart's The Marriage of Figaro, and Zerlina in Mozart's Don Giovanni; the title roles in Gaetano Donizetti's operas Lucia di Lammermoor and Linda di Chamounix; the title role in Die Zigeunerin (The Bohemian Girl) by Michael William Balfe; and Katharina in Der Nordstern (L'étoile du nord) by Giacomo Meyerbeer, who directed the Vienna production in 1855, insisting on Wildauer taking the role.
