English soprano Joan Carlyle, born April 6, 1931 at Upton in Wirral, Cheshire, UK, has died at age 90,  the Royal Opera House has announced.

She had become one of the leading British and English-speaking singers, having emerged at Covent Garden in the 1950s.

Carlyle worked under the baton of many important conductors such as Rafael Kubelik, George Solti, Otto Klemperer and Rudolf Kempe as well as such prominent opera stars as Luciano Pavarotti, Maria Callas, Joan Sutherland, Lisa della Casa, and Dietrich Fischer-Dieskau.

She sang throughout Europe at such venues as the Vienna State Opera, the Berlin State Opera, and the Bavarian State Opera in Munich. Carlyle made her U.S. debut in 1963, performing Brahms’ “German Requiem” with the Austrian conductor Erich Leinsdorf.

Among the operas she performed throughout her career were “Medea,” “Pagliacci,” “Otello,” “Les Troyens,” “La Bohème,” “A Midsummer Night’s Dream,” “The Magic Flute,” and “Le Nozze di Figaro.”

In later years, the soprano lived in Wales and was dedicated to teaching private singing. She also taught master classes and workshops at institutions such as the Royal College of Music in London.
