Stefania Toczyska (née Krzywińska), born in Grudziądz, Poland, on 19 February 1943, is a Polish mezzo-soprano of international repute.
Her debut occurred in 1973, on the stage of the Baltic State Opera House in Gdańsk, in the title role of Carmen, and her fame and prestige began accordingly.
From there, she made frequent guest visits to sing on stages of various opera houses around the world, including her native country, particularly at the Teatr Wielki, Warsaw.
On 16 September 1979 she made her American stage debut in the San Francisco Opera, as Laura in La Gioconda[1] (with Renata Scotto and Luciano Pavarotti), which was telecast "live" around the world.
[2][3] She went on to sing there in Aida, Il trovatore, La Gioconda, Boris Godunov (as Marina Mnichek), Un ballo in maschera (as Ulrica), Rusalka (as Jezibaba) and Adriana Lecouvreur (as the Principessa di Bouillon), with her last performance there, in 1997.
