Carol Ann Susi, the actress who played the role of Mrs. Wolowitz, Howard’s mother, in sitcom The Big Bang Theory, has died after a brief battle with an aggressive form of cancer.

She was 62.

CBS and executive producers Chuck Lorre, Steven Molaro and Bill Prady said in a joint statement: “The Big Bang Theory family has lost a beloved member today with the passing of Carol Ann Susi, who hilariously and memorably voiced the role of Mrs. Wolowitz.

“Unseen by viewers, the Mrs. Wolowitz character became a bit of a mystery throughout the show's eight seasons. What was not a mystery, however, was Carol Ann's immense talent and comedic timing, which were on display during each unforgettable appearance.

“In addition to her talent, Carol Ann was a constant source of joy and kindness to all. Our thoughts and deepest condolences are with her family during this time, and we will miss her greatly.”

A representative for Susi also released a tribute to the late actress.

“A spunky Italian gal from Brooklyn whose passionate interests included Doctor Who, Halloween horror mazes, cooking and the Magic Castle, Carol Ann drew fervent circles of followers,” it read.

“She has a force of nature who didn't suffer fools and was fiercely loyal to her friends. Known only to a very lucky few, she was a world-class culinary genius who frequently scored blue ribbons at the very competitive cooking competitions at the Los Angeles County Fair.”

Susi was first discovered by the casting department at Universal Studios in Los Angeles, after she moved to the city to pursue a career in entertainment in the Seventies.

She went on to secure dozens of small screen appearances, including in cult comedy Cheers, Doogie Howser, M.D., Mad About You, Just Shoot Me, Seinfeld and Six Feet Under.

She also starred in ABC series The Night Stalker as Kolchak's secretary, Monique Marmelstein.

She is survived by her brother, Michael.
