Peggy Mondo played the proverbial "fat lady" of stage and screen. The daughter of ecclesiastical painter Vincent Elipidio Mondo and Emma A. Spignesi, she hailed from New Haven, Connecticut. Beginning her career as a Connecticut Experimental Theater member in the 1950s, she studied voice under the tutelage of 'Francesco Riggio' and 'Hilda Whitworth Riggio', the company's directors. She fulfilled her lifelong desire to perform on 'Broadway' in 1957 upon winning the part of Ethel Toffelmeir in The Music Man. She reprised the role in the film version Le marchand de fanfares (1962). She is remarkably light on her feet in the Shipoopi spectacular with Buddy Hackett. Following this success, Mondo launched her career as a character actress in film and television. She also played the sister with the remarkable voice in the "Landrews Sisters" sketch in the Jack Benny Las Vegas act.
