Carol Ann Susi was an American actress whose career spanned 40 years. Her best known roles were probably her first and last; she debuted as the recurring character of semi-competent but likable intern Monique Marmelstein on Kolchak: The Night Stalker. More than three decades and countless supporting roles later, her level of celebrity was elevated for having provided the voice of recurring off-screen character Mrs. Wolowitz, mother of Howard Wolowitz, on the television series The Big Bang Theory.
