D., Sc. D., is a fictional character in the CBS television series The Big Bang Theory and Young Sheldon, portrayed by actor Jim Parsons in The Big Bang Theory and Iain Armitage in Young Sheldon. For his portrayal, Parsons has won four Primetime Emmy Awards, a Golden Globe Award, a TCA Award, and two Critics ' Choice Television Awards. The character 's childhood is the focus of Young Sheldon ; the series is set in 1989 when 9 - year - old prodigy Sheldon has skipped ahead five grades, to start high school alongside his older brother. Sheldon is a senior theoretical physicist at Caltech and did share an apartment with his colleague and best friend, Leonard Hofstadter ( Johnny Galecki ), until Sheldon moves across the hall with his fiancée Amy, in the former apartment of Leonard 's wife Penny. He is a former child prodigy with genius level IQ, but displays an almost total lack of social skills, a tenuous understanding of humor, and difficulty recognizing irony and sarcasm in other people, although he himself often employs them. He exhibits highly idiosyncratic behavior and a general lack of humility or empathy. He also lacks toleration. These characteristics provide the majority of the humor involving him, which has caused him to be described as the show 's breakout character. Despite speculation that Sheldon 's personality traits may be consistent with Asperger syndrome, obsessive -- compulsive personality disorder, and borderline asexuality, co-creator Bill Prady has repeatedly stated that Sheldon 's character was neither conceived nor developed with regard to any of these traits. Contents 1 Creation and casting 2 Characterization 2.1 Early life 2.2 Personality 2.3 Family 2.4 Relationships 3 Reception and legacy 3.1 General 3.2 Asperger syndrome 4 References Creation and casting The character of Sheldon Cooper was inspired by a computer programmer personally known to series co-creator Bill Prady. He is named in honor of actor / producer Sheldon Leonard and Nobel Prize Laureate Leon Cooper. Chuck Lorre originally intended Johnny Galecki to play the role, but Galecki thought he would be `` better suited '' for the character of Leonard. Lorre said that when Jim Parsons auditioned for the role, he was `` so startlingly good '' that he was asked to reaudition `` to make sure he had n't gotten lucky ''. Sheldon is one of four characters to appear in every episode of the series, along with Leonard, Howard, and Raj. Characterization Early life Sheldon was raised in Galveston, Texas along with his elder brother ( George Jr. ) and fraternal twin sister ( Missy ) by his mother, Mary Cooper, an overtly devout Evangelical Christian ; and George Cooper, an alcoholic who was rarely around. Sheldon once got his father fired when he told Mr. Hinckley, the store owner, that George was stealing from the cash register. ( Sheldon was rewarded with a fudgsicle. ) In Young Sheldon, this is retconned : 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, but 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 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 despise Christmas when his Christmas wish to bring Pop - Pop back did n't come true. Sheldon 's closest relative is his maternal grandmother who he affectionately calls `` Meemaw '', and who in turn calls him `` Moon Pie ''. His aunt also encouraged Sheldon by giving him medical equipment, `` in case his work in physics failed, he 'd have a ' trade ' to fall back on ''. Sheldon was interested in science from an early age, and was a child prodigy, although due to his behavioral quirks and his lack of humility about his superior intellect, he was bullied by classmates and neighbors. ( This has been semi-retconned on Young Sheldon, as most of his high school classmates hardly ever interact with him, and the only neighbor kid shown so far, Billy Sparks, hardly ever does anything to Sheldon, other than scare him with a rooster in the pilot episode - although Young Sheldon begins when Sheldon is 9, so it is possible that Sheldon was bullied before the age of 9. ) Sheldon entered college at the age of eleven, and at age fourteen he graduated from college summa cum laude. ( To this day, the college he went to for undergraduate studies has yet to be revealed, but he feels it is superior to his fellow Big Bang Theory colleagues ' alma maters. ) From then, he worked on his doctorate, was a visiting professor at the University of Heidelberg in Germany, was the youngest person at the time to receive the Stevenson Award, and has appeared on the cover of Journal of Physical Chemistry A. Sheldon is now a theoretical physicist doing research at Caltech. Personality `` Bazinga '' redirects here. For the jellyfish genus, see Bazinga ( genus ). Sheldon is often described as a stereotypical `` geek ''. He is usually characterized as being extremely intelligent, detail - oriented, eccentric, and occasionally disturbing. Despite his intelligence, he often displays childlike qualities, such as being extremely stubborn and a lack of common sense. It is claimed by Bernadette that the reason Sheldon is sometimes unpleasant is because the part of his brain that tells him it is wrong to be nasty is `` getting a wedgie from the rest of his brain '', although, in season 8 's `` The Space Probe Disintegration '', Sheldon tearfully admits to Leonard that he is aware of his peculiarities and how his behavior comes across. The first four episodes of The Big Bang Theory portray Sheldon slightly inconsistently with respect to his later characterization, in which he is depicted as rather witty and sarcastic, and slightly flirtatious towards Penny in the pilot episode : according to Prady, the character `` began to evolve after episode five or so and became his own thing ''. Sheldon possesses an eidetic memory and an IQ of 187, although he claims his IQ can not be accurately measured by normal tests. He originally claimed to have a master 's degree and two doctoral degrees, but this list has increased. Sheldon has an extensive general knowledge in many subjects including physics, chemistry, biology, astronomy, cosmology, algebra, calculus, economics, computers, vexillology, engineering, history, geography, linguistics, football, trains, and in addition to being fluent in Klingon, has some knowledge of Finnish, Hindi and Mandarin. He also shows great talent in music, knowing how to play the piano ( as does Parsons in real life ), the bongos, the recorder, theremin ( which Jim Parsons learned to play in real life ), showing some skill in Tuvan throat singing and also having perfect pitch. Although his friends have similar intellects to him, his eccentricities, stubbornness, and lack of empathy often frustrate them. Sheldon occasionally uses slang ( in a very unnatural fashion ), and follows jokes with his catchphrase `` Bazinga ! '' which is now an officially registered trademark of Warner Bros. He is uncomfortable with human physical contact and has germophobia, which makes his exceptionally rare hugs extremely awkward and painful - looking. He also has hemophobia. Sheldon has difficulty coping when asked to keep a secret, when he is interrupted, or when he hears arguing. He is also a notary public 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 can not logically defend. In his mannerisms, Sheldon also shows symptoms associated with obsessive - compulsive personality disorder. Whenever approaching a person 's home, he must knock three times, then say the person 's name, and must repeat this at least three times ( where `` The first one is traditional, but two and three are for people to get their pants on '' ), as a result of him walking in on his father with another woman when he was thirteen. Upon entering a person 's home, he must select the proper seat before sitting down. When it is suggested by Penny that he `` just sit anywhere '', his response is `` Oh, no, if only it were that simple ! '' This extends to his inability to accept change. His rigidity in maintaining homeostasis often causes him frustration. Because of his rigidity and stubbornness, only his mother and Bernadette -- both possessing strong maternal instincts -- are able to control him. Like his friends, Sheldon is fond of comic books ( especially the DC Universe ), costumes, video games, roleplaying games, tabletop games, collectible card games, and action figures. Sheldon has restraining orders from his heroes Leonard Nimoy, Carl Sagan, and Stan Lee, as well as television scientist Bill Nye. Sheldon often wears vintage T - shirts adorned with superhero logos. One of his shirts is emblazoned with the number 73, and in the episode `` The Alien Parasite Hypothesis '' he explains that 73 is the 21st prime number, its mirror, 37, is the 12th prime number and its mirror ( 21 ) is the product of multiplying 7 and 3, also in binary, 73 is a palindrome, 1001001 which backwards is 1001001. The boys use video games like bowling and archery for `` exercise '' and use the traditional sport rules. Sheldon has sometimes showed empathy, including lending money to Penny without expecting it back quickly ( although that may just have been his logical Spock - like response to a problem to be solved ; it was, after all, money he was not using and would not miss ) and driving her to a hospital when her shoulder was dislocated. 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 contract '' 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 caffeine, due to a promise to his mother, and is hypersensitive when he accidentally consumes them. It has been shown, however, that alcohol often causes Sheldon to loosen up significantly, although it will also cloud his judgment -- on occasion, after drinking alcoholic drinks ( both deliberately and accidentally ), he has done things that he would never do while sober, such as singing out loud, mooning an audience full of people, confronting Wil Wheaton and affectionately slapping Amy 's rear. 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 born - again Christian 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., seen thus far only on Young Sheldon. Both Missy and George Jr. beat up Sheldon during their childhoods ( again, something yet to be shown on Young Sheldon, as they mostly try to disassociate with him there, with the exception of Sheldon twice telling his father that Georgie `` breaks wind on my head '' ), 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. 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, which was revealed in Young Sheldon when his mother told Meemaw that she made dinner for `` Charlene and Edward '' more times than her. Sheldon had another uncle, named Carl Cooper, who was killed by a badger while cleaning a chimney and another uncle that may have done things to children that were legal in Oklahoma per `` The Clean Room Infiltration ''. Sheldon had an uncle, Roger and aunt, Ruth. In `` The Engagement Reaction '', Sheldon mentions Ruth died in a hospital when she went to visit Roger, caught something and bit the dust a week later and the two of them now share a coffee can on Sheldon 's mother 's mantle. 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 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 became close friends. While some fans support a romantic relationship between Sheldon and Penny, Lorre has 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 do n't see any reason to modify it. '' It has been speculated that Sheldon may be asexual or aromantic. Series co-creator Chuck Lorre said : `` Part of what 's wonderful and unique about ( Sheldon ) is he has chosen not to play in the relationship game either way -- heterosexual, homosexual, bisexual, any sexuality. '' This is referenced in `` The Cooper - Nowitzki Theorem '', when Sheldon unknowingly attracts the attention of grad student Ramona Nowitzki, and Penny, seeing this, asks his friends what his `` deal '' ( i.e., sexual orientation ) is, to which Leonard responds, `` Honestly, we 've been operating under the assumption that he has no ' deal '. '' Mayim Bialik ( who portrays Amy Farrah Fowler ) and Jim Parsons at PaleyFest 2013 for the TV show `` Big Bang Theory '' 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 is off the table ''. Their relationship continues in season 4, although Sheldon often points out that they are not in a romantic relationship. 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 unexpectetdly 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 and 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 ca n'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 turns to his Gollum figurine and asks it, `` Well, Gollum, you 're an expert on rings, what do I do with this one ? '', while simultaneously taking his grandmother 's ring, a family heirloom, out of this desk drawer. 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 Platonic Permutation '' Amy offers Sheldon to get back together with her after spending time together in an aquarium at Thanksgiving, but sadly 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 was n't one of them ''. In `` The Earworm Reverberation '', Sheldon ca n't get a song out his head, but after suddenly remembering the title and the lyrics, he realizes that the song was about Amy and that she changed his life for the better, which prompts him to go to her apartment to profess his love. 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 harp with the Los Angeles Philharmonic, 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 compares to his ovinaphobia ), 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. 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 its season finale, Sheldon unexpectedly proposes to Amy after being hit on by Ramona Nowitzki ; the eleventh season premiere was basically a continuation of this, and Amy accepts his proposal. 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 51⁄4 - inch floppy disk ). 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. Sheldon would later resume his enmity with Wheaton in season 11 's `` The Proton Regeneration '' when they compete for the lead role in a reboot of Sheldon 's childhood favorite science TV show and Wheaton gets the part : however, this ends when he sees how good Wheaton is in the role and on the advice of Howard, he apologizes to him. Reception and legacy General Sheldon Cooper doing the Vulcan salute, stencil graffiti on a wall in Volgograd, Russia Jim Parsons ' portrayal of Sheldon has received widespread acclaim, and is often cited as the main reason for the program 's success by critics and fans alike. James Chamberlin of IGN wrote : `` It 's hard to imagine what The Big Bang Theory would be if it were n't for Jim Parsons ' great portrayal of Sheldon Cooper ''. Matt Roush of TV Guide stated that `` there 's a spark of divine inspiration in Jim Parsons ' uproarious Sheldon Cooper ''. Ken Tucker of Entertainment Weekly wrote that : `` Parsons is doing something rare on network TV : making intellectualism admirable, even heroic ''. On July 16, 2009, Jim Parsons was nominated for the Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series. He was nominated again for the same award on July 8, 2010, and eventually won the award on August 29, 2010. On August 1, 2009, he won the TCA Award for Individual Achievement in Comedy, with the show itself winning the award for Outstanding Achievement in Comedy for season two. He was nominated again for the same award in 2010 and 2012. Parsons was also nominated for the People 's Choice Award for Favorite TV Comedy Actor and a Satellite Award for Best Actor -- Television Series Musical or Comedy in 2009, 2010, and 2012. On January 16, 2011, Parsons won the Golden Globe Award for Best Actor -- Television Series Musical or Comedy, presented by co-star Kaley Cuoco, for his work on seasons 3 and 4. On June 20, 2011, he won the Critics ' Choice Television Award for Best Actor in a Comedy Series at the 1st Critics ' Choice Television Awards for his work on season 4, and was nominated again for the same award in 2012. On September 18, 2011, he won his second consecutive Primetime Emmy Award - Lead Actor in Comedy, and was nominated again for the same award on July 19, 2012. In 2013, Parsons was nominated once again for the Golden Globe and received his first nomination for the Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Comedy Series. In 2013 & 2014, Jim was nominated for the Primetime Emmy Award - Lead Actor in Comedy for the 5th and 6th time, respectively, both of which he won for his 3rd and 4th Primetime Emmy Awards - Lead Actor in a Comedy Series meaning that Parsons had won this award 4 times in the last 5 years, including back - to - back in 2010 / 2011and 2013 / 2014. No actor, in the history of this award has won back - to - back awards on two separate occasions, and his total of 4 awards puts Parsons in a four - way tie at the top with comedy legends Carroll O'Connor, Kelsey Grammer, and Michael J. Fox. The asteroid 246247 Sheldoncooper was named after Sheldon. In 2012, a newly discovered species of bee was named Euglossa bazinga, after the character 's noted catch phrase, `` Bazinga ! '' In March 2013, the Columbus Zoo and Aquarium named a black - and - white colobus after Sheldon. In 2015, a new echinocaridid phyllocaridan from the Lower Devonian of central - eastern Poland, was named Ptychocaris sheldoni after Sheldon. Asperger syndrome Some viewers have asserted that Sheldon 's behavior is consistent with Asperger syndrome. The writers have stated that they did not use Asperger syndrome as a basis for the character, but instead thought of his actions as `` Sheldony ''. Series co-creator Bill Prady stated : `` We write the character as the character. A lot of people see various things in him and make the connections. Our feeling is that Sheldon 's mother never got a diagnosis, so we do n't have one. '' Prady also told Alan Sepinwall of the New Jersey Star - Ledger that while Sheldon shares traits with people with Asperger 's, he was uncomfortable labeling Sheldon as having Asperger 's. In an interview, Jim Parsons noted the writers ' response, but added that, in his opinion, Sheldon `` could n't display more traits '' of Asperger 's. Parsons, who plays Sheldon, has read John Elder Robison 's memoir Look Me in the Eye about his life with Asperger syndrome, and said that : `` A majority of what I read in that book touched on aspects of Sheldon. '' He also stated that `` the way his brain works, it 's so focused on the intellectual topics at hand that thinking he 's autistic is an easy leap for people watching the show to make ''. When another actor on the series, Mayim Bialik, who plays Amy and has a Ph. D. in Neuroscience, was being interviewed about Sheldon having Asperger 's with Neil deGrasse Tyson on StarTalk, she stated, `` 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. He has a thing with germs, he has a thing with numbers, he 's got a lot of that precision that we see in 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.
