About Rosa Ponselle
Rosa Ponzillo, known as Rosa Ponselle (January 22, 1897 – May 25, 1981) was an American operatic dramatic soprano. She sang mainly at the New York Metropolitan Opera and is generally considered to have been one of the greatest sopranos of the 20th century. This was further demonstrated in 1954, when RCA Victor came to Villa Pace and recorded Ponselle singing a wide variety of songs and arias. In the late 1940s, Ponselle became the mentor of the fledgling Baltimore Civic Opera Company, providing coaching and voice lessons for the young singers who appeared with the company.
