The Big Bang Theory' actress Carol Ann Susi dies at 62 Actress Carol Ann Susi, whose brash Brooklyn accent reverberated on the hit television series "The Big Bang Theory," has died after a battle with cancer. She was 62. Though she never appeared on camera and was largely unseen, she routinely hollered Howard's name, making her overbearing, husky voice a big part of the show. "The Big Bang Theory family has lost a beloved member today," the show's executive producers said in a statement following her death Tuesday. In addition to her role in "The Big Bang Theory," Susi appeared in shows such as "Cheers," "Mad About You" and "Seinfeld." Susi played the mother of Simon Helberg's character, Howard Wolowitz, in the CBS comedy.
