Opera Singer. She was a dramatic coloratura soprano of wide repertoire who performed throughout Europe in the late 19th Century. Orphaned at an early age, she was adopted by a family named Tremier and started singing as a teenager in Viennese church choirs; married to banker Franz Wilt in 1855, she was a housewife while continuing her choral work. After joining the Vienna Singakademie in 1858 the high quality of her voice was finally recognized leading to training with Joseph Gansbacher and the opportunity for solo work in cantatas and oratorios. Marie made her operatic bow as Donna Anna from Mozart's "Don Giovanni" at Opera Graz in 1865; she sang in Venice, Italy, during the 1866 season and during both 1866 and 1867 appeared, billed as "Maria Vilda" (British audiences had a preference for Italian singers at the time), at Covent Garden, London, where among her portrayals was the title Druid Priestess of Vincenzo Bellini's masterpiece "Norma". Marie joined the Vienna Hofoper in 1867 and was to be a regular there for ten years, her roles including Donna Elvira in "Don Giovanni", the title heroine of Verdi's "Aida", Leonore from the same composer's "Il Trovatore", and the Queen of the Night from Mozart's "The Magic Flute"; on March 10, 1875, she was Sulamith for the Vienna world premiere of Karl Goldmark's "The Queen of Sheba". During her Vienna years she traveled extensively numbering among her roles the title characters of Rossini's "Semiramide" and Donizetti's "Lucrezia Borgia", while also performing the soprano solo parts of Beethoven's Ninth Symphony and "Missa Solemnis", and other choral works. Over the final years of her career Marie changed her base of operations several times, first to Leipzig, then Frankfurt, thence to Budapest, and finally back to Vienna, earning special praise as Brunnhilde in Wagner's "Ring". In 1886 she was chosen to sing Donna Anna in performances at the Salzburg Festival to honor the piece's 100th. anniversary. Following her 1890 retirement the by-then widowed Marie moved in with her married daughter; she committed suicide by jumping from a hotel window after she was jilted by a younger lover.
