At 91, Claudia Pinza was still teaching voice at Duquesne University and the University of Pittsburgh. She was also taking on private students and directing the Ezio Pinza Council for American Singers of Opera — an internationally acclaimed summer training program based in Pittsburgh and Oderzo, Italy, in honor of her father, star of opera and Broadway, Ezio Pinza.

A former singer with the Metropolitan Opera, Ms. Pinza never stopped working. She was giving lessons in her Bellevue home to Met Opera countertenor Andrey Nemzer as recently as the start of July. She remained an active board member of Pittsburgh Opera, as well as a warm and welcoming hostess, whose authentic Italian dinners at her Bellevue home were famous among her friends and colleagues.
