Sylvia Fisher (18 April 1910 – 25 August 1996) was an Australian operatic soprano whose stage career was made in England, who was especially distinguished in German opera, and who created the role of Miss Wingrave in Benjamin Britten's Owen Wingrave in 1971.
Born in Melbourne, Fisher studied the piano from the age of nine, and afterwards entered the Albert Street Conservatorium for singing and voice production and obtained the full diploma. When this was completed she continued her singing studies with Adolf Spivakovsky, and worked with him for many years. She made her debut as a student in Lully's Cadmus et Hermione at the Comedy Theatre, Melbourne, on 5 March 1932, at the Lully Tercentenary Festival. This was her only stage appearance in opera in Australia, but she rapidly became well-known there as a concert artist and broadcaster.
Her concert and broadcast repertoire included many operatic arias, and she sang in many broadcasts of complete operas, notably in the title role of Verdi's Aida, as Donna Anna (Mozart's Don Giovanni) and as Ortrud (Wagner's Lohengrin). She also established herself as a fine lieder and oratorio singer in Australia.
It was as an established singer, therefore, that she went to England in 1947, and was first heard there in lieder recitals in BBC broadcasts. She joined the Covent Garden resident company in 1948 and rapidly gained approval. Her debut there was as Leonora (Beethoven's Fidelio), after which she appeared in several smaller parts such as the First Norn (Götterdämmerung) and the First Lady (The Magic Flute). She soon became the company's leading dramatic soprano. In 1949 she made a further powerful impression with her Countess in The Marriage of Figaro and her Elsa in Lohengrin, and also made her first and highly successful appearance in a role thereafter much identified with her, as the Marschallin in Richard Strauss's Der Rosenkavalier.
