ned: his father is a football coach who was fired from his coaching position in Galveston because he disclosed that other coaches were illegally recruiting players to their school, forcing the family to return to Medford. He does drink, mostly beer, and is a loving father who is trying to understand his intellectually gifted son. The only member of his family to have actively encouraged his work in science was his maternal grandfather, whom he cherished and affectionately called "Pop-Pop", and who died when Sheldon was five years old. Pop-Pop's loss is what caused Sheldon to not like Christmas very much when his Christmas wish to bring Pop-Pop back did not come true. Sheldon's closest relative is his maternal grandmother whom he affectionately calls "Meemaw", and who in turn calls him "Moon Pie". His aunt was also said to have encouraged his work in science by giving him medical equipment, "in case his work in physics failed, he'd have a 'trade' to fall back on". In ''Young Sheldon'', it is shown that his childhood friend Tam was the one who introduced him to non-scientific interests such as comic books and ''

Throughout the entire run of ''The Big Bang Theory'', the college he went to for undergraduate studies had not been revealed, but he always felt it was superior to his fellow ''Big Bang Theory'' colleagues' alma maters of Princeton (Leonard), Cambridge (Raj), MIT (Howard) and Harvard (Amy); however, it is implied in "The Tam Turbulence" (Season 12, Episode 4) that Sheldon is in fact a Caltech alumnus, and in ''Young Sheldon'' he is said to enroll at the fictional East Texas Tech before finally enrolling at Caltech in the final episodes of the series.

Personality

Like Leonard, Raj, and Howard, Sheldon is characterized as being highly intelligent, but he tends to display childish qualities, such as extreme stubbornness and meanness. It is claimed by Bernadette that the reason Sheldon is sometimes mean is because the part of his brain that tells him it is wrong to be mean is "getting a wedgie from the rest of his brain". However, in season 8's "The Space Probe Disintegration", Sheldon tearfully admits to Leonard that he is aware of how his behavior comes across. The first four episodes of ''The Big Bang Theory'' portray Sheldon slightly inconsistently with respect to his later characterization: according to Prady, the character "began to evolve after episode five or so and became his own thing". Sheldon frequently states that he possesses an eidetic memory (although his powers of autobiographical recall are more like hyperthymesia) and an IQ of 187, although he claims his IQ cannot be accurately measured by normal tests. He originally claimed to have a master's degree and two

and uses his knowledge in law and contracts usually for his own advantage and is always distressed when challenged in a legal aspect that he cannot logically defend. In his mannerisms, Sheldon also shows symptoms associated with obsessive-compulsive personality disorder, as is suggested within the show itself by Amy in regard to how, whenever approaching the door of an occupied room—say the bathroom—he must knock three times, then say the person's name, and must repeat this three times; this was revealed as a result of him seemingly walking in on his father with another woman (although in reality it was just his mother roleplaying) when he was thirteen ("The first nockis traditional, but 'two' and 'three' are for people to get their pants on."). Upon entering a person's home, he must select the proper seat before sitting down. When it was suggested by Penny that he "just sit anywhere", his response is "Oh, no, if only it were that simple!" Because of his rigidity and stubbornness, only his mother and Bernadette, both possessing strong maternal personalities, have shown the ability to order him to do things. Like his friends, Sheldon is fond of comic books (mostly from the

In the season 6 episode "The Decoupling Fluctuation", Amy secretly tells him that Penny is considering breaking up with Leonard. Struggling to keep the secret from Leonard, Sheldon wakes up Penny in the middle of the night and asks her not to hurt his friend. In the Season 8 finale, he expresses his genuine happiness for Leonard and Penny when they decide to finally get married in Las Vegas (although his position was briefly reversed during the Season 9 premiere after he and Amy broke up). Since season 10, his empathy and caring attitude toward others have improved to the extent that he goes out of his way to pamper his fiancée Amy. Sheldon admits he is overly fond of koalas munching on eucalyptus so much that he has a facial expression that he refers to as his koala face. He dislikes gifts, because the "social convention" in his view creates either a debt or burden on the receiver of the gift which will not stop until one of the two involved in the "gift-relationship" dies leaving the other either in debt or with an undue surplus. Sheldon also does not take drugs, not even legal ones such as

, and affectionately slapping Amy's rear. After consuming caffeine in the form of coffee or energy drinks, typically on the rare occasions that he has to work beyond his normal working hours to meet a deadline, he acts in a hyperactive, erratic manner. In response to criticism from his friends that he is mentally ill, Sheldon often retorts, "I'm not crazy; my mother had me tested"; which his mother has confirmed to be true, once while wishing she had gone through with a follow-up examination.


Family

Sheldon contrasts strongly with his family, who are neither scientists nor intellectuals. His father George died before the start of ''The Big Bang Theory'', when Sheldon was 14, while his mother Mary is a devout Baptist and loving parent. Sheldon has two siblings: a twin sister, Missy, who is a tall, attractive brunette as an adult; and an older brother, George Jr., who owns a tire store chain headquartered in

called Dr. Tire. The adult Sheldon has stated that both Missy and George Jr. beat up Sheldon during their childhoods, and their mother describes them to be "dumb as soup". In the pilot episode of ''The Big Bang Theory'', Sheldon tells Leonard that DNA is not a guarantee of an intelligent offspring as he himself is a theoretical physicist and his twin sister is a hostess at Fuddruckers: in the series finale of ''Young Sheldon'', he has a similar conversation with Amy regarding their children. Sheldon is very fond of his maternal grandmother, whom he calls "Meemaw" and who calls him " Moon Pie". He called his grandfather, who died when Sheldon was five, "Pop Pop". Sheldon was also very close to his grandfather, stating once that his grandfather is the only relative he had who encouraged him to become involved in science. Sheldon has a maternal uncle, Edward, who is called "Stumpy" as the result of a time when he cleaned a wood chipper by hand. He also has a maternal aunt, Charlene, revealed in ''Young Sheldon'' when his mother told Meemaw that she made dinner for "Charlene and Edward" more times than she did. Sheldon had another uncle, Carl Cooper, who was killed by a badger while cleaning a chimney, and another uncle who may have done things to children that were legal in Oklahoma per "The Clean Room Infiltration". In "The Engagement Reaction", Sheldon mentions that his aunt Ruth died a week after being infected by a pathogen she contracted in the hospital where she visited Sheldon's Uncle Roger and that their ashes are now stored in a coffee can on Sheldon's mother's mantle. ''Young Sheldon'' confirms that Ruth is George's sister and that she and Roger are still alive by 1990. In the ''Young Sheldon'' episode "Vanilla Ice Cream, Gentleman Callers, and a Dinette Set", it is revealed that Sheldon has children in the future, but this is never referenced or confirmed in ''The Big Bang Theory''. In the ''Young Sheldon'' episode "

" (season 4 episode 1), Sheldon mentions his son, Leonard Cooper. He says that he wanted to name him Leonard Nimoy Cooper, but his wife Amy objected. In the ''Young Sheldon'' series finale, Sheldon is shown to also have a daughter (whose name is not revealed) with Amy. In ''The Big Bang Theory'', Sheldon did express an interest in having children with Amy, albeit an unfeasibly large number in order to serve as subjects for social or behavioral experiments.


Relationships

Sheldon's closest friends are Leonard Hofstadter, Howard Wolowitz, and Raj Koothrappali. Of the three, Sheldon is openly dismissive of Howard and constantly opines that a master's degree in engineering demonstrates a lesser intellect than that of the others, who all possess science doctorates. Despite that, Sheldon has referred to Howard as a "treasured acquaintance" and later his friend at various points. Sheldon constantly belittles Leonard and dismisses his work, yet at the same time considers Leonard his best friend, as they used to live together and can tolerate each other: in "The Space Probe Disintegration", Sheldon admits to Leonard that he is aware of how difficult he can be, and tearfully expresses his gratitude for having Leonard in his life in spite of himself, causing Leonard to break down beside him. Prady stated that "the fact that, despite everything, Leonard considers Sheldon his best friend reminds us of Sheldon's essential humanity". Sheldon can only handle having a limited number of friends in his life at a time, but later shows flexibility when he accepts Bernadette and Amy as part of the social group. In season 6, the guys ask if comic book store owner Stuart can be part of the group while Howard is in space. Despite Penny's neither being a scientist nor sharing many of the group's interests, and having constant fights with Sheldon in the early episodes, they become close friends. While some fans supported a romantic relationship between Sheldon and Penny, Lorre stated his opposition to it by saying: "We've stumbled into creating a character who has chosen a lifestyle for himself that is unique. And I don't see any reason to modify it." He once idolized fictional prodigy Wesley Crusher from '' Star Trek: The Next Generation'', portrayed by Wil Wheaton, until Wheaton did not show up at a convention attended by Sheldon in 1995. Sheldon had spent 15 hours on a bus travelling to the convention during which time he was forced to break his rule about urinating in a moving vehicle. After this moment Wil Wheaton became number six on Sheldon's mortal enemy list (a list he started when he was 9 on a 5¼-inch

). Wheaton was one of Sheldon's mortal enemies, along with his coworkers Barry Kripke and Leslie Winkle. Later, Wheaton managed to patch things up with Sheldon, only to inadvertently pass the enemy list spot to Brent Spiner, who removed the packaging from a signed Wesley Crusher action figure presented to Sheldon as a gift. Sheldon would later resume his enmity with Wheaton in season 11's "The Proton Regeneration" when they compete for the lead role in an Internet reboot of Sheldon's childhood favorite science TV series, ''Professor Proton'', with Wheaton getting the part; however, when he sees how well Wheaton plays the role and on the advice of Howard, he apologizes to him. It has been speculated that Sheldon may be asexual or

after eating too much Thai food. In the season 3 finale, Howard and Raj blackmail Sheldon into meeting Amy Farrah Fowler, with whom they matched him on a dating website. After some obnoxious comments about the dating website, Sheldon finds that Amy agrees with him, and he grows fond of her when she says that "Any or all physical contact up to and including coitus are off the table". Their relationship continues in season 4, although Sheldon often points out that they are not in a romantic relationship (stating that she "is a girl who is a friend, but is not my girlfriend"). The two enjoy intellectual games they create, and Amy and Sheldon openly express the same type of intellectual superiority. In season 5, when Leonard inadvertently implies that he and Amy may have had sex after a wedding reception that they both attended, Sheldon unexpectedly reacts violently, karate-chopping Leonard's neck while telling Leonard "She is not for you... not for you!" Later, Sheldon formally asks Amy to be his girlfriend in " The Flaming Spittoon Acquisition". During their relationship, Amy begins a campaign to give Sheldon more attention to increase his feelings for her by embracing his interests. As they watch Howard being launched into space in its season finale, Amy is surprised when Sheldon takes her hand for emotional support. During the first half of season 6, in " The Parking Spot Escalation" and " The Fish Guts Displacement", Sheldon is pushed further after seeing Amy partially exposed and taking care of her while she is ill respectively. In " The Cooper/Kripke Inversion", after being directly asked by Penny if he would ever have sex with Amy, Sheldon admits to Penny and Leonard that a physical relationship with Amy is a possibility, and being touched is something he is working on. While upset about Kripke, Amy does give him a consoling hug that Sheldon seems to need, and want. Even so, Amy has offered other romantic physical contact, and was very uncomfortable when they had to cuddle. In " The Spoiler Alert Segmentation", Leonard temporarily moves out and Amy proposes that she would be his perfect roommate and tries to move in, though Sheldon is uncomfortable with this change in their relationship. While playing ''Dungeons & Dragons'' during " The Love Spell Potential", Sheldon's and Amy's characters are commanded to have sex within the game. A very upset Amy asks Sheldon if they are ever going to be intimate and he again admits that it is a possibility. In season 7, Sheldon passionately kisses Amy on the lips for the first time. Initially to prove a point, he later prolonged it, implying he enjoyed the feeling. Later episodes showed him willingly kissing Amy, implying he has gotten more comfortable in such a position of physical intimacy. The ultimate proof of Sheldon having feelings for Amy is given in the season 8 episode " The Prom Equivalency", when he finally admits being in love with her: "I love you too. There's no denying I have feelings for you that can't be explained in any other way. I briefly considered I had a brain parasite, but that seems even more far-fetched. The only conclusion was love." In the season 8 finale, " The Commitment Determination", Sheldon and Amy get into a fight over their definition of "commitment". Sheldon feels his relationship with Amy is going fast on its own, but Amy argues he is taking things too slowly and does not properly bestow on her unlimited affection. By the episode's end she has decided to take a break from their relationship while Sheldon is left numb from Amy's revelation. He glumly reveals that he had been planning on proposing to Amy with his grandmother's ring - a family heirloom. In the season 9 premiere, Sheldon keeps pushing Amy to make up her mind about their relationship, but goes too far and insults her to her face and she angrily breaks up with him for good, thus officially ending their relationship. In "The Perspiration Implementation", Barry Kripke learns that Amy is no longer in a relationship and implies an interest in asking her out on a date. Sheldon is bothered by this notion and challenges Barry in a duel that will end three years hence. In " The Platonic Permutation" Amy offers Sheldon a chance to get back together with her after spending time together in an aquarium at Thanksgiving, but learns that he simply just wants to be her friend, with him revealing to her that "I excel at many things, but getting over you wasn't one of them". In " The Earworm Reverberation", Sheldon cannot get a

He finds Amy on a date with Dave, who has a great adoration for Sheldon because of his intellect. Seeing how much they love each other, Dave gleefully urges Sheldon to kiss Amy, leading to their reunion. In the following episode, " The Opening Night Excitation" Leonard, Howard and Raj go to see '' Star Wars: The Force Awakens'' without Sheldon as while he was initially reluctant, ultimately opted to celebrate Amy's birthday with her instead. To make Amy's birthday enjoyable and memorable, Sheldon seeks out Penny and Bernadette as he respects their opinions regarding all things socially appropriate. He reveals to them that he has narrowed things down to three options, the first being a chance to play the

, the second being an all-expense-paid trip to the Wisconsin Sheep and Wool Festival (though Amy would have to go alone because Sheldon's ornithophobia is nothing compared to his fear of sheep), and the third being the two of them engaging in coitus, at which point Penny squeezes and shatters the wine glass in her hand due to disbelief and/or shock. After Penny and Bernadette convince him that finally being intimate with her is the most beautiful gift that he could give to her, Sheldon and Amy have sex for the first time on the latter's birthday. Sheldon comments, "I enjoyed that more than I thought I would". In season 10, Sheldon and Amy move in together for a five-week experiment to test out their compatibility, and after its successful run, decide to move in together permanently. In "The Holiday Summation", Mary Cooper confesses to being accepting of Sheldon and Amy living together out of wedlock in the privately held belief that Sheldon would never be in a relationship, which deeply offends him. In the tenth-season finale, Sheldon unexpectedly proposes to Amy after being kissed by Ramona Nowitzki, a graduate student who had been infatuated with him in earlier seasons. In the eleventh-season premiere, Amy accepts his proposal, and they marry in the season finale. Late in season 12, Amy is preparing Sheldon to accept the prospect of having children by getting him to have fun experimenting with the Wolowitz children. In the series finale, both Sheldon and Amy are recipients of the

his family, his friends and his wife Amy for always supporting him. He also refers to Howard as "Astronaut Howard Wolowitz", exhibiting, for the first time, some level of pride in having a friend who was an astronaut. He also admits that he agrees with what Leonard said in the Pilot episode, that Leonard and Penny's children will be "smart and beautiful". At the end of season one of ''Young Sheldon'', the adult Sheldon refers in voice over to having had children: in season 4, it is revealed that one of them is a son named Leonard, and banter between the adult Sheldon and Amy implies that their son was meant to be named after both Leonard Hofstadter and Leonard Nimoy. In the series finale of ''Young Sheldon'', it is revealed that Sheldon's other child is a daughter, and that Sheldon's children appear to have interests contrary to his, such as athletics and acting.

All of our characters are in theory on the neuropsychiatric spectrum, I would say. Sheldon often gets talked about in terms of Asperger's or OCD.

There's a lot of interesting features to all of our characters that make them technically unconventional socially. And what we're trying to show with our show is that this is a group of people who likely were teased, mocked, told that they will never be appreciated or loved, and we have a group of people who have successful careers, active social lives (that involve things like ''Dungeons and Dragons'' and video games), but they also have relationships, and that's a fulfilling and satisfying life.
