Roberta Peters is the Bronx-born coloratura soprano who at 20 was catapulted to stardom by a phone call, a subway ride and a Metropolitan Opera debut.
Ms. Peters, who would sing with the Met 515 times over 35 vigorous years, was internationally renowned for her high, silvery voice (in private, she could hit a high A, two and a half octaves above middle C); her clarion diction in a flurry of languages; her attractive stage presence; and, by virtue of the fact that she and television came to prominence at about the same time, her wide popular appeal.
