What is Bernadette Rostenkowski's full maiden and married name?

Bernadette Rostenkowski's full maiden and married name is Bernadette Maryann Rostenkowski-Wolowitz.

Bernadette is introduced with the surname Rostenkowski and later marries Howard Wolowitz. Her complete name combines her given names, her original family name, and her married surname: Bernadette Maryann Rostenkowski-Wolowitz. The character is played by Melissa Rauch.

Before becoming a microbiologist, Bernadette works with Penny at The Cheesecake Factory while using her wages to support her graduate studies. She eventually earns a PhD and builds a career in pharmaceutical research. Her scientific career contrasts with Howard's aerospace engineering work, while both characters remain connected through their marriage and family life.

The spelling and structure of her name can cause confusion because the series usually calls her simply Bernadette or Mrs. Wolowitz. “Bernadette Mary Rostenkowski” omits her middle name, while “Bernadette Rose Wolowitz” changes both the middle name and family-name history.
