Opera Singer. A soprano, she is remembered as both a Wagnerian performer and as a distinguished voice teacher. The child of a noted composer, she was educated at the Prague Conservatory and later in Vienna where she met Richard Wagner. Hired at the Munich Hofoper, she made her 1866 professional bow as the title Druid Priestess of Vincenzo Bellini's "Norma", then over the next few years was to assume a variety of Wagnerian roles, most notably Elsa in "Lohengrin" and Elisabeth from "Tannhauser", and on June 21, 1868 was Eva for the world premiere of "Die Meistersinger" under the baton of Hans von Bulow. Moving on to Berlin in 1869, she continued to sing Wagner's music while adding several significant parts to her repertoire, among them the title leads of Verdi's "Aida" and Beethoven's "Fidelio", Valentine from Meyerbeer's "Les Huguenots", Agathe in Carl Maria von Weber's "Die Freischutz", and at least three Mozartean ladies, La Contessa from "The Marriage of Figaro", Donna Anna of "Don Giovanni", and Pamina from "The Magic Flute". While in Berlin she engaged in a feud with soprano Pauline Lucca, with each lady having their claque of disorderly fans who yelled and at times even came to blows; the matter peaked at a January 27, 1872 performance of "The Marriage of Figaro" which featured Mathilde as La Contessa and Pauline as Cherubino, with Mathilde's fans booing Pauline off the stage, in the process driving her out of Berlin. She was to make guest appearances at the Marinsky Theatre of St. Petersburg and at the Vienna State Opera, retired from the operatic stage in 1883, and continued giving recitals until 1895. A teacher in Prague from 1890 until 1895, she later held a faculty appointment at Berlin's Eichelbergersche while being a much sought-after private instructor, with several of her students, most notably Lotte Lehmann, achieving major international careers. Mathilde was designated Kammersangerin (KS) in 1916; as far as can be determined, she made no recordings.
