NYTimes Obit Born as Maria Maddalena Olivero in Saluzzo, Italy, she made her operatic debut in 1932 on radio in Turin radio singing Nino Cattozzo's (1886–1961) oratorio, I misteri dolorosi. She performed widely and increasingly successfully until 1941, when she married and retired from performing. She returned to the stage ten years later, at the request of Francesco Cilea, who asked her to sing again the title role in his opera Adriana Lecouvreur. From 1951 until her final retirement, Olivero sang in opera houses around the world. Among her most renowned interpretations were the leading parts in Adriana Lecouvreur, Iris, Fedora, La bohème, La fanciulla del West, La traviata, La Wally, Madama Butterfly, Manon Lescaut, Mefistofele, and Turandot (as Liù).
