Bernadette Rostenkowski-Wolowitz

Bernadette Maryann Rostenkowski, Ph.D., is a waitress at the Cheesecake Factory paying her way through graduate school microbiology studies. She has been dating Howard off and on since The Creepy Candy Coating Corollary and as of The Herb Garden Germination, they are engaged.

Family
Not much is known about Bernadette's family. Howard joked that her parent's names were Adolf and Eva, even thought he hadn't met them yet. Her surname indicates she has German descent. Bernadette's mother used to make Bernadette crazy like Howard's mother does to Howard. She used run an illegal day care in the basement and wouldn't let Bernadette ride a bike because she was worried she would hit a bump and lose her virginity (which she eventually lost in a Toyota Camry). Bernadette's father workes as a police officer and ahe always worried for his safety.

Howard
Main article: Howard and Bernadette



Bernadette has been dating Howard since The Creepy Candy Coating Corollary. Bernadette was introduced to Howard by Penny because of a pact Leonard made with Howard. After that, Bernadette dated Howard for a few more episodes until Howard announce that they have broken up "a few weeks ago" in The Plimpton Stimulation. In The Hot Troll Deviation, Howard revealed the reason they broke up and after he apologized they started dating again. In The Herb Garden Germination, Howard proposed to Bernadette and she accepted. However, Bernadette's relationship is strained due to Howard still living with his mother and his sensitivity.



Penny
Bernadette knew Penny before the rest of the gang as she worked as a waitress at the Cheesecake Factory with Penny. By the fourth season they have become good friends and occasionally go on a girls night out. Bernadette doesn't like Priya because she sides with Penny after Priya announced her relationship with Leonard.

In "The Wildebeest Implementation", Priya invites Bernadette and Howard over to dine with her and Leonard. Amy talks her into spying on Priya and Leonard for Penny but she eventually can't handle the pressure of lying and leaves abruptly.

Amy
Amy and Bernadette are 'Good friends' as they have girls nights with Penny. In the episode The Wildebeest Implementation, Amy had given the nickname 'Wildebeest' to Bernadette, but doesn't really appreciate Amy calling her that. In "The Isolation Permutation", due to the guilt she felt for leaving Amy out and went bridesmaid dress shopping alone with Penny, she decided to make Amy her maid of honor. Even though she has known Penny longer than Amy and seems to get along better with Penny because of that, she still has more  similarities with Amy in terms of academic. The both of them are doctorate holders with majors under the branch of Biology. In "The Ornitophobia Diffusion", Sheldon called both of them biologists and asked them to get rid of the bird that had flown into his apartment and landed on his spot on the couch.

Leonard
Bernadette became friends with Leonard shortly after Penny introduced her to the Howard. She became interested in Leonard's experiments, but they are only friends as Howard and Bernadette are in a relationship (even though Howard felt threatened by this).

Occupation
Bernadette worked at the Cheesecake Factory with Penny to pay off her fees at Graduate School, studying to become a microbiologist. She met Howard at work as Penny introduced the couple. In the present, Bernadette has received her Ph.D, and was offered a job at a big pharmaceutical company.
