The Big Bang Theory main characters [edit]

Leonard [edit]

Leonard Leakey Hofstadter^[2] (portrayed by Johnny Galecki; seasons 1-12) is an experimental physicist with an IQ of 173. Originally from New Jersey, he received his PhD at age 24, spending at least some of his time at Princeton University. He shared an apartment in Pasadena with colleague and friend Dr. Sheldon Cooper for much of the series. Unlike his equally geeky friends, Leonard is interested and adept in building relationships with other people. Compared to his friends, he is relatively successful with women. Leonard comes from an accomplished family. His mother, Dr. Beverly Hofstadter, is a neuroscientist and world-renowned psychiatrist with whom he has a strained relationship. His sister is a medical researcher. His father, Dr. Alfred Hofstadter, is an anthropologist. And his brother Michael is a Harvard law professor. He and Penny date on and off throughout the series eventually marrying and finding out they're pregnant in the series finale.

Leonard makes a brief non-speaking cameo as a child in the Season 2 finale of Young Sheldon; he was portrayed by Isaac Harger as a child.

Sheldon [edit]

Sheldon Lee Cooper (portrayed by Jim Parsons; seasons 1-12) is a theoretical physicist, possessing a B.S, M.S, M.A,^[3] Ph.D, Sc.D, and an I.Q. of 187 and an eidetic memory. Born in East Texas, he was a child prodigy, and received his Ph.D at age 16 from the California Institute of Technology. He is a cold, condescending, self-centered, and immature person but is rarely malicious. He is obsessed with routines and any disruptions distresses him enormously. He shows signs of obsessive–compulsive personality disorder often show through his compulsive need to knock three times on a door whilst saying the name of the person behind the door 3 times too and the superiority complex. Despite his lack of social graces, he does care about his friends and family. In seasons 1–9, he shares an apartment in Pasadena with friend and fellow physicist Dr. Leonard Hofstadter. From then after he moves in with his girlfriend and eventual wife Amy. It is revealed in Young Sheldon that they have kids too.

His interest in science fiction and comic books borders on the extreme. He has a particular affinity for Spock from the Star Trek franchise. Although he has the tendency to take things literally, he is fond of occasionally telling a joke or playing a prank, which he typically punctuates with his trademark exclamation "Bazinga!"

Penny [edit]

Penny (portrayed by Kaley Cuoco; seasons 1-12), is Leonard and Sheldon's neighbor across the hallway. Originally from a small town outside Omaha, Nebraska, she was a waitress and occasional bartender at the local Cheesecake Factory until season seven, and is an aspiring actress. Kind-hearted and outgoing, Sheldon described her as a "good-natured simpleton" but was critical of her dropping out of community college.

Initially, not much is known about Penny's family, but it is mentioned in the series that her father, Wyatt (portrayed by Keith Carradine,^[4]) raised her like a boy, her mother smoked marijuana while she was pregnant with her, her sister shot her husband while they were intoxicated, and her brother is a meth dealer. Her mother, Susan (Katey Sagal), and brother, Randall (Jack McBrayer), are finally seen in the first episode of season ten. Her last name is never revealed during the series. Leonard and Penny date on and off throughout the series which is a big plot point of the show, they eventually marry and find out they're pregnant in the series finale.

Penny makes a brief non-speaking cameo as a child in the Season 2 finale of Young Sheldon, she was portrayed by Quinn Aune as a child.

Howard [edit]

Howard Joel^[5] Wolowitz, M.Eng. (portrayed by Simon Helberg; seasons 1-12) is an aerospace engineer at Caltech's Department of Applied Physics, who often hangs out at Leonard and Sheldon's apartment. Unlike Sheldon, Leonard, and Raj, Howard does not have a doctorate, and often gets disparaged as a result, especially by Sheldon. He defends this by pointing out that he has a master's degree in Engineering from MIT and that the equipment he designs is launched into space, unlike the theoretical work of his friends. In the fifth-season finale, Howard goes to the International Space Station on Expedition 31.

Howard lives in Altadena with his domineering, belittling, and unseen mother, who treats him like a child. While he sometimes expresses irritation at this treatment, for the most part, he appears to prefer it.^[6] Howard and his mother often communicate with each other from different rooms by yelling, a habit which Bernadette also adopts in later episodes. Howard fancies himself a ladies' man and attempts pick-up lines whenever a woman is present, although he drops this habit once he starts going out with Bernadette. He is a non-observant Jew. Throughout the series he and Bernadette marry and have two children.

In the pilot episode, he speaks English, French, Mandarin, Russian, Arabic, and Persian, along with fictional languages like Klingon and Sindarin. Howard suffers from asthma, transient idiopathic arrhythmia, allergies to peanuts, almonds, and walnuts, and is prone to canker sores and pink eye.

Howard makes a brief non-speaking cameo as a child in the Season 2 finale of Young Sheldon, he was portrayed by Ethan Stern as a child.

Raj [edit]

Rajesh Ramayan^{[7] [8]} Koothrappali, PhD (portrayed by Kunal Nayyar; seasons 1-12) is Howard Wolowitz's best friend. Often called "Raj" by his friends, he is from New Delhi, India, and works in the physics department at Caltech, researching astroparticle physics. Raj comes from a very wealthy family in India, and often communicates with his parents, Dr. and Mrs. Koothrappali, via webcam. Like most of the scientists bar Howard he also has a PHD. ^[9] He has a younger sister, Priya. He lives in an apartment in Pasadena. As with his friends, he is mutually involved with and obsessed with science fiction and comic books in general. He is also a fan of Harry Potter and Indian music, but appreciates the Indian lullabies his mother sang and the catchiness of Hindi phrases. Unlike his male friends, Raj has many feminine interests, such as reading Archie comics and Twilight and watching chick flicks such as Bridget Jones's Diary. It is speculated that Raj might be gay due to his feminine interests and his close friendship with Howard, with whom he has arguments similar to those of a married couple. However, Raj has always stated that he is straight, but metrosexual. He was infatuated with Penny, and secretly wrote love poems about Bernadette.

Raj is a Hindu and believes in karma (reincarnation), but eats beef. He is very shy around women outside of his family, and during the first six seasons of the show, found himself unable to speak to women while in their presence unless he drank alcoholic beverages, or believed he had done so.^[9] He eventually is able to get over this condition and starts to, unsuccessfully and for short periods, date women.

Raj makes a brief non-speaking cameo as a child in the Season 2 finale of Young Sheldon, he was portrayed by Rishabh Prabhat as a child.

Leslie [edit]

Leslie Winkle, PhD (portrayed by Sara Gilbert; main: season 2; recurring: season 1; guest: seasons 3 & 9) is an experimental physicist who shares her lab with Leonard. In appearance, she is essentially Leonard's female counterpart, equipped with black-framed glasses and sweat jackets. She suffers from lazy eye. She is one of Sheldon's arch-enemies, due to their conflicting scientific ideas, and takes every opportunity to insult Sheldon for mistreating her.

Bernadette [edit]

Bernadette Maryann^[10] Rostenkowski-Wolowitz,^[11] PhD (portrayed by Melissa Rauch; main: seasons 3-12; recurring: season 2) is originally a waitress and co-worker of Penny's at The Cheesecake Factory, using her wages to pay for her graduate studies in microbiology. She is a smart, short-tempered, ruthless, manipulative bully and often competitive young woman with a squeaky voice who sometimes displays a nice and friendly personality. Despite her short stature, she is regarded as being somewhat intimidating, largely because of her sharp tongue, aggressive demeanor, and occasional signs of mania. A recurring joke in the series references Bernadette and her lab team handling dangerous or infectious specimens, leading to accidental byproducts or exposure to diseases, in some cases resulting in Bernadette being quarantined. She and Howard have two children throughout the series and move into Howard's childhood home.

Bernadette is of Polish origin and Catholic upbringing, and was originally seen wearing a cross necklace.

Bernadette makes a brief non-speaking cameo as a child in the Season 2 finale of Young Sheldon, she was portrayed by A. J. Coggeshall as a child.

Amy [edit]

Amy Farrah Fowler, PhD (portrayed by Mayim Bialik PhD; main: seasons 4-12; guest: season 3) is a neuroscientist with a research focus on addiction in primates and invertebrates, occasionally mentioning such experiments involving addiction. (Bialik herself has a PhD in neuroscience.) She is Sheldon's love interest in the series whom she marries at the end of season 11. They are revealed to have children in Young Sheldon.

Early on, Amy is essentially a female counterpart to Sheldon, but later on, she begins a campaign to increase Sheldon's feelings for her by becoming more involved in his interests, including video games and Star Trek, and treating him as his mother did.

In 2020, a year after The Big Bang Theory went off the air, it was revealed that Kate Micucci, who ultimately got the role of Lucy, had auditioned for the role of Amy Farrah Fowler.^[12]

Amy makes two appearances in Young Sheldon. She makes an appearance as a child in the Season 2 finale where she is portrayed in a non-speaking role by Lily Sanfelippo. Bialik returns to play Amy in the narration of the season 4 premiere.

Stuart [edit]

Stuart David Bloom^{[13] [14]} (portrayed by Kevin Sussman; main: seasons 6 & 8-12; recurring: seasons 2-5 & 7) runs the Comic Center in Pasadena,^[15] the comic book store that the characters often visit. Stuart is characterized by his low self-esteem and loneliness, which often result in pathetic attempts to engage with women and win favor with the main cast. This is despite owning his own (albeit troubled) business, and being a talented portraiture artist who attended the Rhode Island School of Design.^[16]

Kevin Sussman was a recurring guest actor from seasons two to five, and was promoted to starring role for the sixth season onwards.^[17]

Emily [edit]

Emily Sweeney, M.D., (portrayed by Laura Spencer; main: season 9; recurring: seasons 7-8; guest: season 10) is a dermatology resident at Huntington Hospital, whom Raj finds on an online dating site. Emily went to Harvard and is shown to have a slightly alarming personality trait: she delights in the macabre.

Laura Spencer was a recurring guest actress on the series in seasons seven and eight. During production of season 9, she was promoted to a "fractional" starring role; the upgraded status ensured her availability on an as-needed basis, without requiring her in every episode.^[18] She returned as a guest in season 10.

Young Sheldon main characters [edit]

Sheldon Lee Cooper [edit]

Sheldon Lee Cooper (portrayed by Iain Armitage; seasons 1-present) is a child prodigy who finishes primary school before his twin sister Missy and joins the same high-school class as his older brother Georgie at the age of nine. He reads widely and possesses an eidetic memory. He prefers to learn topics that interest him on his own—such as Faraday's law of induction and gravitational lensing—than the standard curriculum of grade school. In this series, the origins of his interests in the sciences, engineering, computers, trains, comic books, science fiction (especially the character Spock from Star Trek) are revealed. Sheldon moves on to college while Missy remains in middle school. Despite their rivalry, Sheldon and Missy are closer than first appears.

Mary Cooper [edit]

Mary Cooper (née Tucker) ^[19](portrayed by Laurie Metcalf in The Big Bang Theory; recurring: seasons 7 @ 9-12; guest: seasons 1 & 3-5 and by Zoe Perry in Young Sheldon; seasons 1-present) is Sheldon's loving and deeply religious mother from Texas. She is able to control Sheldon, with Leonard once describing her to Penny as "Sheldon's Kryptonite". A devout Southern Baptist, she also has two other children — Sheldon's twin sister Missy and brother Georgie, who is about three or four years older than the twins. Her husband, a rambunctious alcoholic, was also named George but he later died in Sheldon's childhood. To Mary's relief, her other children do not share Sheldon's precociousness, even once commenting to Leonard, "I thank the good Lord my other kids are as dumb as soup". Mary herself is not intellectual but is quite wise, though she is prone to making outdated and insensitive remarks. She is nevertheless kind at heart and is tolerant of other faiths. Leonard wishes his mother were as loving as Sheldon's mother, although Sheldon himself appears at best ambivalent about her parenting. Sheldon mentions that Mary once hit him with a Bible because he refused to eat his Brussels sprouts. She apparently thought something was wrong with her son while he was growing up, as Sheldon will often remark after someone calls him crazy, "I'm not crazy; my mother had me tested!" Mary confirms this, though she wishes that she had taken him to Houston for further testing.

A younger version of Mary is a main character in the prequel series Young Sheldon. Perry is Metcalf's real life daughter.

George Cooper Sr. [edit]

George Cooper Sr. is the father of Georgie, Sheldon, and Missy and the husband of Mary Tucker-Cooper. In The Big Bang Theory, it is established that he died when Sheldon and Missy were fourteen years old. He is portrayed by Lance Barber (seasons 1-present) who previously portrayed Jimmy Speckerman in one episode of The Big Bang Theory. (guest: season 5) George works as a football coach.

George "Georgie" Cooper Jr. [edit]

George "Georgie" Cooper Jr. (portrayed by Jerry O'Connell as an adult; recurring: seasons 11-12 and Montana Jordan as a youth; seasons 1-present) is Sheldon and Missy's older brother who resides in Texas and runs a car tire business. Often at odds while growing up, the Cooper brothers later reconciled their differences. George Jr. is a laid back character who likes to make money.

Melissa "Missy" Cooper [edit]

Melissa "Missy" Cooper (Courtney Henggeler as an adult; guest: seasons 1, 7 & 11 and Raegan Revord as a child; seasons 1-present) is not as academically accomplished as her twin brother but displays better social skills. In season three of Young Sheldon, Missy joins the baseball team in the fictional town of Medford. While Sheldon finishes high school and matriculates at university, Missy navigates the ordinary challenges of adolescence. Despite their differences, the twins are pretty close; they are both atheists.

As an adult in The Big Bang Theory, Missy is a tall, attractive woman who promptly catches the attention of Leonard, Howard, and Raj. She occasionally visits Sheldon, whom she introduces to her friends as a "rocket scientist".

Constance "Connie" Tucker ("Meemaw") [edit]

Constance "Connie" Tucker^[19] (June Squibb in The Big Bang Theory; guest: season 9 and Annie Potts in Young Sheldon; seasons 1-present) is Mary's mother, George Sr.'s mother-in-law and maternal grandmother to Georgie, Sheldon and Missy, who call her "Meemaw". Like Sheldon's other family members, she is also native to Texas and is their next-door neighbor at the town of Medford. Sheldon sees himself as her favorite grandchild, whom she affectionately calls "Moonpie". Sheldon, in turns, is very affectionate and protective toward her. Meemaw is often mentioned to by Sheldon, but did not appear on the series until episode 14 of season nine, "The Meemaw Manifestation".

In Young Sheldon, a recurring theme is her significant gambling habit.

Pastor Jeff Difford [edit]

Pastor Jeff Difford (portrayed by Matt Hobby; main: seasons 3-present; recurring: seasons 1-2) is the upbeat lead pastor of a local Baptist church at Medford that Sheldon's family attends in Young Sheldon. Like Mary, he too sometimes has friction with Sheldon's atheistic side but often recommends Sheldon to explore his own ideas logically.

Billy Sparks [edit]

Billy Sparks (portrayed by Wyatt McLure; main: seasons 5-present; recurring: seasons 1-4) is a boy who lives with his parents and sister next to the Coopers and Meemaw. He has been mentioned in The Big Bang Theory as one of Sheldon's childhood bullies, although in Young Sheldon he is rather good-natured and at times is friends with Sheldon, but is shown to be extremely dim-witted and simple-minded.

Arthur Jeffries [edit]

Arthur Jeffries, or Professor Proton (Bob Newhart) is the star of a fictional in-universe science show that Sheldon and Leonard watched as children. The character is a homage to Mr. Wizard.^[21] After the show was cancelled, Jeffries was not taken seriously as a scientist and resorted to doing children's parties as his persona. When Sheldon asks for his wisdom, Jeffries tells Sheldon to appreciate everything in life, including his friends, and never take it for granted.

For his role as Jeffries, in 2013, Newhart won his first Primetime Emmy Award. Newhart plays the same character on Young Sheldon.

Barry Kripke [edit]

Barry Kripke, PhD (John Ross Bowie) is a colleague working in plasma physics who frequently clashes with Sheldon. Kripke has a case of rhotacism in which he pronounces the letters "R" and "L" as "W" in much the same way as Elmer Fudd from Looney Tunes, Jimmy Five from Monica's Gang and Gilda Radner in her "Baba Wawa" sketches.

Beverly Hofstadter [edit]

Beverly Hofstadter (Christine Baranski) is Leonard's unloving and overly analytical mother who works as a neuroscientist, as well as a psychiatrist. She is Sheldon's female equivalent regarding neurotically strict speech patterns, disregard for social conventions, and compulsive attention to detail. The lack of Beverly's maternal feelings and actions toward Leonard has led to him having an obsessive need to please. Mrs. Hofstadter and Mrs. Cooper do not get along.

For her role as Beverly, in both 2009 and 2010, Baranski was nominated for an Emmy Award for Outstanding Guest Actress in a Comedy Series.

Claire [edit]

Janine Davis [edit]

Janine Davis (Regina King) is a human resources representative working at the university. She first appears in season six after Sheldon offends his assistant Alex while trying to deal with her crush on Leonard, leaving Mrs. Davis to handle Alex's sexual-harassment complaint against Sheldon.

Kurt (Brian Patrick Wade) is a tall, intimidating bodybuilder and Penny's ex-boyfriend at the beginning of the series.

Lucy [edit]

Lucy (Kate Micucci) shows up at a party at the comic-book store on Valentine's Day at an event for people who had no dates. She has social anxiety issues, which allows Raj and her to connect.

Originally, Kate Micucci had been one of the actresses considered for the Amy Farrah Fowler character.

Mike Rostenkowski [edit]

Mike Rostenkowski (Casey Sander) is Bernadette's father and a retired police officer. Mike has a rough and rude personality and often bullies others, although he deeply loves his daughter, calling Bernadette his "little girl". Before he is first seen, Bernadette establishes his personality by telling Howard a long list of subjects he cannot discuss with Mike, including Jimmy Carter, foreigners, homosexuals, and even Howard's Jewish identity.

President Siebert [edit]

President Siebert (Joshua Malina) is the president of the California Institute of Technology. Often mentioned by Sheldon, a recurring gag is that Sheldon often calls or visits Siebert in the middle of the night to get information, and usually gets a bitter response. In season eleven, the President returns to support Sheldon and Amy's work in physics.

Priya Koothrappali [edit]

Priya Koothrappali (Aarti Mann) is Raj's younger sister. Having graduated at the top of her class at the University of Cambridge (where like Sheldon, her roommate was from Texas), she is one of the lead attorneys at India's biggest car company.

Wil Wheaton plays a fictionalized version of himself. Wil played Wesley Crusher in Star Trek: The Next Generation, a character that Sheldon idolized as a child. In 1995 Wheaton made Sheldon's "mortal enemy" list after Wheaton failed to show up at a fan convention. Sheldon took a 10-hour bus ride to attend the convention and was disappointed that Wheaton was a no-show.

Wil Wheaton, LeVar Burton, Leonard Nimoy (in voice-over only), Brent Spiner, William Shatner and George Takei have all appeared on the show, making the Star Trek franchise the most represented franchise on the show in terms of guest appearances.

Marissa Johnson [edit]

Marissa Johnson (Lindsey Kraft) is married to Penny's ex-boyfriend, Zack Johnson. They meet with Leonard and Penny and they want Leonard to father their child since Zack is infertile.

Mrs. Wolowitz [edit]

Mrs. Debbie^[24] Malvina^[25] Wolowitz (voiced by Carol Ann Susi) is Howard's over-protective, controlling, belittling, but loving and caring stereotypical Jewish mother. The character is not shown on-screen with the exception of one episode in season six in which her body, but not her face, is briefly shown. Mrs. Wolowitz's raspy voice is heard usually in scenes at her house, which she shares with Howard. She talks to Howard always by yelling at him from another room, which results in awkward conversations with Howard yelling back at her. In a flashback, when the guys hear her yelling in a masculine voice, they ask Howard if that was his father, to which Howard replies, "If she grows any more hair on her face, yes." Mrs. Wolowitz is also described as being enormously obese and wearing a wig and painted-on eyebrows. She seems to be oblivious to Howard's work as an engineer and treats him as though he is still a child. She is a master at Wheel of Fortune and guessing answers at game shows. She frequently refers to Leonard, Sheldon, and Raj as Howard's "little friends" (as in, "I made some cookies and Hawaiian Punch for you and your little friends!") and often refers to Caltech as a "school". Howard often makes references to his mother as being a "crazy old lady", but deep down, he is deeply attached to his mother and quite happy to be treated like a child. She is also noted to be on hormone replacement therapy, and she wants to "play doctor" with Raj when he asks to sleep over.

Wyatt [edit]

Wyatt (Keith Carradine) is Penny's father. He comes to visit, and Penny feels compelled to involve Leonard in a ruse to make him think they are still together. (Wyatt reveals that he favors the successful Leonard over Penny's other "loser" boyfriends.)

Zack Johnson [edit]

Zack Johnson (Brian Thomas Smith) is a dim-witted but friendly beefcake type whom Penny dates on and off after her second break-up with Leonard. Zack works as the menu designer for restaurants that are owned by or which have hired his father's company to design their menus. Later, Penny and Zach go out to a party, but she is so put off at how stupid he is that she runs back to Leonard for sex, saying he ruined her ability to tolerate stupid men. In season four, Zack runs into Penny, Bernadette, and Amy at a restaurant, and Amy becomes physically attracted to him. Sheldon arranges a meeting between Zack and Amy to satisfy her "urges" but his lack of intellect immediately discourages Amy.

Later, Penny runs into Zack again after he buys her, Bernadette and Amy drinks. He reveals that he has sold his menu company and become rich from the profits, and invites her and Leonard to dinner at his yacht with him and his new wife, Marissa Johnson.

Young Sheldon [edit]

Brenda Sparks [edit]

Brenda Sparks (Melissa Peterman) is Billy Sparks's mother who works at the bowling alley frequented by Meemaw. She frequently clashes with Mary due to her religious status.

Dr. John Sturgis (Wallace Shawn) is a physics professor at the university East Texas Tech that Sheldon attends part-time. Dr. Sturgis is initially a pen pal of Sheldon Cooper, before the child prodigy audits his course on quantum chromodynamics. Dr. Sturgis is instantly smitten with Sheldon's Meemaw and they begin dating. He is also rather childish like going to bed at 7:30 and asking Meemaw's permission to do things as if she were his mother.

Herschel Sparks [edit]

Herschel Sparks (Billy Gardell) is a neighbor of the Cooper family and Meemaw, the husband of Brenda Sparks, and the father of Billy and Bobbi Sparks. He runs his own garage, where he offers Georgie a part-time job. Georgie turns out to be a wonderful employee, something that makes George and Herschel happy and stunned. Herschel is often bossed around by his wife, something that he and George bond over since George is often bossed around by Mary as well, in the fourth season Brenda divorced him possibly for his affections towards Mary.

Paige [edit]

Paige Swanson (Mckenna Grace) is a 10-year-old child prodigy whom Sheldon meets in one of his classes with Dr. Sturgis. As his rival, she teases him about differentiating under the integral sign. She has higher social skills than Sheldon and is capable of being friends with non-intellectuals. She reacts negatively to her parents' divorce. Dr. Sturgis advises Sheldon to listen to her problems, which he does and this results in Sheldon learning to listen. He attempts to console her by making her a hot beverage.

Robin [edit]

Robin (Mary Grill) is a police officer and Pastor Jeff's second wife. Pastor Jeff meets Robin in "A Broken Heart and a Crock Monster" when she stops him for passing a red light. She takes an interest in him and because of that, refuses to give him a ticket.

Veronica Duncan (Isabel May) is Georgie Cooper's most significant love interest on Young Sheldon. Initially introduced as a popular and "easy" girl, Veronica becomes a devout Christian after going through a "Hell house" one Halloween. Georgie is obsessed with her and frequently takes every advantage he can to be close to her or impress her in any way.

Minor characters [edit]

• Althea Robinson (Vernee Watson): makes an appearance in the pilot episode as an attendant at a sperm bank, and then makes three appearances as an emergency room nurse in "The Peanut Reaction" episode (season one) and "The Robotic Manipulation" episode (season four), and as a ward nurse in "The Werewolf Transformation" (season five). The name of the character is never used on the show, but is included on her name tag and in the credits. She is also the only character besides Leonard and Sheldon to be carried over from the original unaired pilot. Watson also portrays a younger version of Robinson in several episodes of Young Sheldon.
• Dr. Stephanie Barnett (Sara Rue): a medical doctor and a highly distinguished surgeon that Howard tries to seduce, but she falls for Leonard. She dates Leonard, and surreptitiously moves in with him. Once Sheldon and Penny point this out to him, Leonard breaks up with her.
