What is Howard Wolowitz's mother's first name?

Howard Wolowitz’s mother is named Debbie.

For much of The Big Bang Theory, she is referred to simply as Mrs. Wolowitz or Howard’s mother. Her first name, Debbie, is eventually stated in the series, making “Debbie Wolowitz” the canonical answer rather than a fan-created nickname or inference.

Debbie is one of the show’s best-known unseen characters. Viewers hear her booming voice from inside the Wolowitz home or during phone conversations, but the character is almost never shown directly. That running gag helped make her overprotective relationship with Howard a recurring source of comedy.

Actress Carol Ann Susi provided Debbie’s voice throughout the series. The character’s off-screen presence contrasts with Howard’s later family life with Bernadette, who becomes his wife and the mother of their children. Susan and Mary are names associated with other characters’ families, while Beverly is Leonard Hofstadter’s mother, not Howard’s.
