Captain Montgomery Scott (often referred to as Scotty by his shipmates) was a male Human Starfleet officer in the 23rd century. His serial number was SE 19754 T. For a period of nearly thirty years, he was the chief engineer of both the USS Enterprise and the USS Enterprise-A, both under the command of Captain James T. Kirk. Having the reputation as a "miracle worker", he was a man of superior technical and engineering skill, experience and ingenuity. Despite his superior talents as an engineer, he was often the source of comic relief among the Enterprise crew due to his use of Scots language. (TOS: "Wolf in the Fold", "Where No Man Has Gone Before", "The Trouble with Tribbles", "The Doomsday Machine", "The Savage Curtain"; Star Trek III: The Search for Spock; Star Trek V: The Final Frontier; Star Trek VI: The Undiscovered Country; TNG: "Relics")
Early life and career Edit
Upon being asked how he adjusted to space travel, Scott once admitted, "I was practically born to it." (TOS: "The Lights of Zetar") He joined Starfleet and began his engineering career in 2241. During his 51-year career in Starfleet, he served on a total of eleven ships, including various freighters, cruisers and starships. (TNG: "Relics") He also briefly served as an engineering adviser on the freight line between the Deneva colony and the outlying asteroid belts. (TNG: "Relics"; TOS: "Operation -- Annihilate!")
He was the writer of several technical manuals, which included Operating Protocol - Flow Sensors. A copy of this manual was stored in the Engineering Systems Database aboard the USS Enterprise-D in 2366. (TNG: "Booby Trap") He was also responsible for writing Starfleet Regulation 42/15, entitled "Pressure Variances in IRC Tank Storage", which was part of the basic operational specifications for impulse engines. These specifications were admittedly written "a wee bit" conservatively. (TNG: "Relics")
The five-year mission Edit
In 2265, Scott was assigned to the USS Enterprise where he served as second officer and chief engineer under Captain James Kirk. (TOS: "Where No Man Has Gone Before") The Enterprise was the first ship on which he was the chief engineer. (TNG: "Relics")
His duties also included maintenance and operation of the Enterprise's transporter systems. Three of his top engineers included Lieutenants Kyle, Leslie, and Gabler. He was understandably upset when Harper, an assistant engineer who was one of only twenty crewmembers selected to remain aboard the Enterprise during the M-5 multitronic unit test mission, was killed by an energy transfer beam used by the insane supercomputer to draw power directly from the ship's warp engines. (TOS: "The Ultimate Computer"; TAS: "One of Our Planets Is Missing", "The Terratin Incident")
As the ship's second officer, Scott assumed command when both Kirk and Spock left the ship, or they both were incapacitated. Thus, he often faced critical diplomatic and military situations. (TOS: "A Taste of Armageddon", "Journey to Babel", "Friday's Child", "Bread and Circuses", "A Piece of the Action") In 2268 Kirk noted him to commendation for his outstanding command performance without disobeying the Prime Directive and saving the landing party on planet 892-IV. (TOS: "Bread and Circuses") However in 2267, Kirk jokingly "fired" Scott when he couldn't repair the ship's engines and break out of orbit around Gamma Trianguli VI. After the destruction of Vaal Kirk immediately "re-hired" him. (TOS: "The Apple") Despite being a capable command officer he never pursued his own command post because he "...never wanted to be anythin' else but an engineer." (TNG: "Relics")
By the late 2260s, Scott knew more about the warp engines aboard a Constitution-class starship than the men who designed them. (TOS: "The Apple") This knowledge and ability to save the ship in a jam eventually led to his reputation aboard the Enterprise as a "miracle worker." This was brought about by his reputation for being able to effect starship repairs faster than usually required. Scott later admitted that he often padded his estimates of time needed for repairs by a factor of four in order to appear that much faster. (Star Trek III: The Search for Spock; TNG: "Relics")
In 2268, Scott stated that he knew the Enterprise better than Larry Marvick, the man who designed the starship. When Marvick visited the ship, escorting the Medusan Ambassador Kollos, Scott made a bet, that he won't find his way around the engine room. When Scott allowed him to the warp engine controls, Marvick, under the madness brought on by the sight of the Medusan, attempted to take over the vessel, and hurled it into the void surrounding our galaxy. (TOS: "Is There in Truth No Beauty?")
In 2267, Scott was attacked and killed by Nomad, a probe originally launched from Earth in the early 21st century. Kirk was distraught by the death of his valued chief engineer, but Nomad informed Kirk that Scott could be "repaired" and the probe revived Scott in sickbay. Later, Scott assisted Kirk and Spock in beaming Nomad out into open space before it exploded from Kirk talking it to death. (TOS: "The Changeling")
Later in 2267, Scott was thrown against a bulkhead of the Enterprise during an explosion. This resulted in a severe concussion and possible amnesia. He was ordered to take time off for therapeutic shore leave on the planet Argelius II. While on Argelius he got into "a wee bit of trouble," as he later described it, when he was accused of murdering an Argelian woman named Kara. Scott's situation worsened when he was accused of two more murders, those of another Argelian, Sybo, and fellow officer Karen Tracy. Scott was later acquitted of the murder charges, following the discovery of a non-humanoid lifeform called Redjac in the form of Mr. Hengist, who was found to be responsible for the murders, and who admitted to being Jack the Ripper and other serial killers in previous incarnations. (TOS: "Wolf in the Fold"; TNG: "Relics")
Scott was extremely proud of the Enterprise. In fact, he was so proud that he once started a bar fight aboard Deep Space Station K-7 when the Klingon named Korax suggested that the ship should be hauled away as garbage. As a result, he was confined to his quarters by Kirk. Scott smiled and told Kirk the punishment would give him a chance to catch up on technical journals he had not had time to read. Shortly after the incident at K-7, Scott managed to rid the Enterprise of the tribbles which had infested the ship. Much to the pleasure of Captain Kirk, Scott, in collaboration with Spock and McCoy, beamed the tribbles aboard the IKS Gr'oth where they would be "no tribble at all". (TOS: "The Trouble with Tribbles")
In 2268, Scott helped Kirk, Spock and McCoy regain control of the Enterprise after the ship was invaded by agents of the Kelvan Empire and set on a course to the Andromeda Galaxy. Before leaving the Milky Way Galaxy, Scott and Spock devised a plan to destroy the Enterprise at the galactic barrier, but Kirk decided against it. Later Scott tried to incapacitate the Kelvan agent Tomar by drinking various alcoholic beverages with him. He got Tomar so drunk that the alien passed out, but his plan was foiled when Scott passed out before he could leave his quarters. (TOS: "By Any Other Name")
In the same year the Enterprise was hurled hundreds of light years away from a Kalandan outpost, and sabotage accelerated the ship to dangerously high warp speeds. Scott risked his life by entering the access crawlspace to the matter-antimatter reaction chamber to repair the fused matter-antimatter integrator, a procedure so dangerous that it was not to be undertaken while the integrator was in operation. When a faulty magnetic probe nearly ruined the procedure, Scott demanded that Spock eject him from the chamber into space, but Spock risked critical seconds to allow the engineer to successfully complete his task. (TOS: "That Which Survives")
In 2268, Scott's position as second officer and chief engineer required him to participate in executing the auto-destruct sequence to prevent Bele from hijacking the Enterprise to return Lokai to the planet Cheron. (TOS: "Let That Be Your Last Battlefield") Scott also threatened the female Romulan Commander that he would use the auto-destruct to destroy the Enterprise and "as many of you as we can take with us" when it was surrounded by Romulan vessels during its espionage mission to appropriate the Romulans' cloaking device. (TOS: "The Enterprise Incident")
Also, in 2268, Scott prevented Garth of Izar from escaping the Elba II asylum to board the Enterprise when he challenged Garth, who, in the guise of Kirk, had attempted to order Scott to transport him to the ship, by requiring Garth to provide the countersign to the prearranged chess problem. (TOS: "Whom Gods Destroy")
Scotty was romantically involved with Starfleet sciences division specialist Lieutenant Mira Romaine at least when she was aboard the Enterprise during its mission to Memory Alpha. Scott figured prominently in the successful attempt to prevent Romaine's body from being appropriated by the Zetarians. In carrying her occupied person to McCoy's decompression chamber, Scott insisted to Kirk, "Mira will not hurt me." Nevertheless, he was thrown across the room by their influence. (TOS: "The Lights of Zetar")
In 2268, Scotty was present in the transporter room along with Kirk, Spock and Lieutenant Dickerson when Presidential honors were rendered to the Excalbian who had taken the form of U.S. President Abraham Lincoln. He scoffed in suggesting sarcastically that "Lincoln" would be followed by "...[King] Louis of France and [fourteenth-century King of Scots] Robert the Bruce!" (TOS: "The Savage Curtain")
Later career Edit
In March 2285, Scott was a participant in Saavik's Kobayashi Maru scenario at Starfleet Training Command. Though not present on the bridge simulator, his voice was heard on the speakers. After the scenario, he served aboard the Enterprise under the command of Captain Spock. He was the ship's chief engineer for a three week training cruise. Upon receiving a call for help from Regula I, Starfleet Command ordered an investigation by the Enterprise. With Rear Admiral Kirk assuming command, the cruise was cut short. The Enterprise became involved with Project Genesis and Khan Noonien Singh's attempt to steal the Genesis Device. Eventually, Kirk was able to stop Khan, but not before the latter had wrought extensive damage upon the Enterprise, requiring Captain Spock to sacrifice his life to save the ship. One of the casualties was Scott's nephew Peter Preston. Scott played the bagpipes at Spock's funeral. (Star Trek II: The Wrath of Khan)
With the Enterprise safely at Spacedock, Scott was promoted to captain and reassigned to the USS Excelsior as Captain of Engineering during the ship's early test runs. Scott detested his assignment aboard the Excelsior, citing the ship as little more than a "bucket of bolts", and didn't particularly care for Captain Styles either. He later sabotaged the Excelsior, removing components from her transwarp computer drive. This prevented the ship from jumping to transwarp drive when the Enterprise was stolen for an unauthorized mission to the Genesis planet.
When arriving at the Genesis planet, a Klingon Bird-of-Prey ambushed the Enterprise and opened fire, disabling Scott's automation system and leaving the ship as "a sitting duck". Scott, along with Kirk and Chekov, initiated the Enterprise's auto-destruct sequence to prevent it from falling into Klingon hands. The crew beamed down to the planet, where they watched their beloved ship burn up in the atmosphere. This would later in life affect Scott emotionally, when he comments that the Enterprise was "his home and where he had a purpose". (Star Trek III: The Search for Spock; TNG: "Relics")
In 2286, Scott traveled back in time to 1986 along with the rest of the Enterprise crew to find a pair of humpback whales. In order to construct a water tank for them, he visited the Plexicorp facility as "Professor Scott" from Edinburgh. Making a deal with plant manager Nichols he gave him the formula of transparent aluminum in exchange for a sheet of plexiglass. When Dr. McCoy objected against "changing the future," Scott pointed out "How do we know he didn't invent the thing?". After returning home, he was reassigned as chief engineer of the newly commissioned USS Enterprise-A. (Star Trek IV: The Voyage Home) For three weeks, after a shakedown cruise, the flaws in the starship's systems were being identified and repaired under the supervision of Scott. (Star Trek V: The Final Frontier)
Scott played a role in exposing the Khitomer conspiracy in 2293. Upon beaming down to the surface of Khitomer, he shot Colonel West, who was about to assassinate the Federation president and kill Lieutenant Valeris, out of a window and several stories to his death. (Star Trek VI: The Undiscovered Country)
Scott appeared as a "guest of honor" along with his former commanding officer, James T. Kirk, and his old crewmate, Commander Pavel Chekov, for the maiden voyage of the new Excelsior-class USS Enterprise-B, commanded by John Harriman. When the Enterprise-B responded to the distress call from two El-Aurian transports, Scott assisted in beaming a small group of survivors on board – 47 out of a total of 150. When the Enterprise became trapped in the energy ribbon the transports were in, Scott formulated a theory to use an antimatter discharge to disrupt the ribbon long enough for the vessel to break away. After Captain Kirk modified the deflector relays to emit a resonance burst, Scott and Hikaru Sulu's daughter Demora were able to get the Enterprise clear. However, a hull breach was created on the secondary hull by the ribbon on the ship's way out and Kirk was presumed to be blown out into space. Upon being asked by Commander Chekov if anyone was in the deflector control room on deck 15 when it was hit, Scott stared out the breach into space and solemnly stated "Aye". (Star Trek Generations)
In 2294, following his retirement from Starfleet, Scott traveled aboard the USS Jenolan to the Norpin colony, where he planned to spend his retirement. The Jenolan, however, encountered a Dyson sphere en route, and while attempting to investigate it, the transport crashed on its surface. Scott and fellow engineer Matt Franklin were the only survivors. Together they rigged the Jenolan's transporter systems, and existed for nearly 75 years in the ship's transporter buffer. (TNG: "Relics")
In 2369, Montgomery Scott was rescued by the USS Enterprise-D, but Franklin's pattern was too degraded to be recovered. After Scott helped rescue the Enterprise-D from the Dyson sphere, Captain Picard rewarded him with the Enterprise's shuttlecraft Goddard. (TNG: "Relics")
Family and personal life Edit
Scott had at least one sister, whose youngest child, Peter Preston, served aboard the Enterprise in 2285 as a midshipman during a Starfleet Academy training cruise. Preston was killed when the Enterprise was attacked and severely damaged by the USS Reliant in a surprise attack by Khan Noonien Singh. Scott was grief-stricken after the tragedy. (Star Trek II: The Wrath of Khan)
Scott had a love for good Scotch whisky, often making references to drinking or frequenting drinking establishments on more than one planet, even referring to himself once as an "old Aberdeen pub-crawler." (Star Trek V: The Final Frontier; TOS: "Wolf in the Fold") He considered Scotch a drink for real men as opposed to, for instance, vodka which he referred to as "sodapop" and "milk diet". (TOS: "The Trouble with Tribbles")
He took shore leave reluctantly, and ran into trouble during shore leave on at least three occasions: a fistfight on Deep Space Station K-7, (TOS: "The Trouble with Tribbles") an arrest for murder on Argelius, (TOS: "Wolf in the Fold") and a "wee bout" requiring Dr. McCoy's attention. (Star Trek II: The Wrath of Khan)
He also played bagpipes, most notably playing "Amazing Grace" at the funeral for Captain Spock in 2285. (Star Trek II: The Wrath of Khan) He was also fascinated to be handling an old fashioned Scottish claymore. (TOS: "Day of the Dove")
Romantic relationships Edit
Although a gentleman at heart, life as an engineer for Scott was often lonely, as he often attempted to pursue hopeless relationships with much younger female officers that were often perceived as being out of his league.
Years later, Commander Uhura began to show some romantic interest in Scott while she was under Sybok's influence. Scott politely declined her advance mindful of her condition. Their relationship was never pursued. (Star Trek V: The Final Frontier)
Memorable quotes Edit

Background information Edit
Montgomery Scott was played by actor James Doohan in all of the character's television and cinematic appearances set in the "prime" universe.
The character of Scotty mostly originated from James Doohan himself. Doohan was asked by Director James Goldstone, to whom he auditioned for another role only ten days prior, to come in and read a few lines from the script of TOS: "Where No Man Has Gone Before" for him, Gene Roddenberry, Robert Justman, Joseph D'Agosta and Morris Chapnick. The role he was proposed for was an unnamed Chief Engineer. Goldstone asked him to do some accents, while Doohan did several ones, including Irish, Scottish, English, Russian, etc. Roddenberry asked him which one he would choose, and he said Scottish, due to Scotsmen being renowned for having great engineering skills. Thus, the character became Scottish, and it was apparently Doohan who named him "Scotty". (The World of Star Trek), 
Gene Roddenberry nearly dropped Scott from the series after the second pilot. He informed Doohan's agent, Paul Wilkins, that "we don't think we need an engineer in the series". Wilkins became irate and met with Roddenberry that day, and insisted on returning Doohan to the Enterprise, which turned out to be a favorable decision. (Inside Star Trek: The Real Story, pp 152-153)
- Engineer Officer Scott is a wizard at repairing everything from the reading light on the captain's bunk to the ship's huge "space warp" engines. In an era of almost complete automation, his ability to fix things with a piece of baling wire or a rubber band has proven invaluable on more than one occasion. (reprinted in Inside Star Trek: The Real Story)
- ENGINEERING OFFICER MONTGOMERY SCOTT: Played by James Doohan, Scott holds the rank of lieutenant commander, senior engineering officer on the U.S.S. Enterprise. With an accent that drips of heather and the Highlands, he is known to most as "Scotty".
- Scotty came up through the ranks, and his practical education is as broad as his formal training in engineering. He has rare mechanical capacity - many claim he can put an engine together with baling wire and glue... and make it run. He regards the U.S.S. Enterprise as his personal vessel and the engineering section as his private world, where even Captain James Kirk is merely a privileged trespasser.
- Engineering and spaceships are his life. His idea of a pleasant afternoon is tinkering in any engineering section of the vessel; he is totally unable to understand why any sane man would spend reading time on anything but technical manuals. He is strong minded, strong willed, and not incapable of telling off even a Starfleet captain who intrudes into what Scotty regards as his own private province and area of responsibilities. (Star Trek: The Original Series 365)
Although Doohan had lost the middle finger on his right hand during the Allied invasion of Normandy on D-Day, Scott had a right middle finger within the Star Trek storyline; any time a closeup was seen of Scott's right hand (working the transporter controls, etc.), someone else's hands were used, and when Scott appeared in wide shots, he usually hid his right hand from the camera. His loss was most evident in TNG: "Relics", where the missing finger can be clearly seen in wide shots while talking to Captain Picard on the holodeck recreation of the original Enterprise bridge and in Star Trek V: The Final Frontier, when Scotty is holding a bag of food.
There was much debate, especially in Scotland, as to which Scottish city Montgomery Scott was born in. The character once described himself as an "Aberdeen pub crawler" in TOS: "Wolf in the Fold". Confusing the matter was a 1970s interview with James Doohan in which he stated his belief that Scott came from Elgin, a town forty miles west of Aberdeen. Linlithgow, twenty miles west of Edinburgh has also been vocal in its claim, citing D.C. Fontana's novel Vulcan's Glory. If either of these claims were correct, it would imply Scott had a relatively genteel upbringing, as the regional accent of Aberdeenshire was far more coarse and Gaelicised than Scott's. On the death of James Doohan, the local West Lothian Council announced plans to open a memorial exhibition for James Doohan in Linlithgow to commemorate his contribution to the Star Trek universe and make the town's claim to be the future birthplace of Montgomery Scott concrete. The exhibition, held at Annet House, Scott's "official" future childhood home opened in the summer of 2007. It was worth noting that in the non-canon story published in the UK comic magazine TV21 & Joe 90 #21 in 1970, Scott described his ancestors as "highlanders". According to Who's Who in Star Trek #2 (DC Comics, April 1987), Scott was born in Glasgow. His actual accent implied he was raised in or near Edinburgh.
Simon Pegg, who portrayed Scotty's alternate self in 2009's Star Trek and its sequels (and was a Star Trek fan long before being cast in the role), concocted his own backstory for the character to settle the debate over the character's accent. 
One inconsistency that involved Scott was that, when the USS Enterprise-D rescued him from the transporter buffer of the USS Jenolan in "Relics", Commander William T. Riker said that he was from the "USS Enterprise". Hearing this, Scott assumed "Jim Kirk himself" had arrived to find him; however, the film Star Trek Generations established that, before Scott embarked on his trip on the Jenolan, he witnessed Kirk get blown off the Enterprise-B, and though not known to him, into the Nexus, so he should have known Kirk wasn't alive to be able to find him. This was caused by the fact that the movie Star Trek Generations was filmed after "Relics", causing a retcon. (In what may have been an attempt to address the discrepancy, in the novelization of Generations, Guinan tells Chekov that Kirk is, in fact, alive within the Nexus, though this information may not have reached Scotty.) According to Ronald D. Moore, who wrote both "Relics" and Generations, Scott was included in the latter, despite the inconsistency, out of affection for the character. (Star Trek Chronology)
Another minor inconsistency could be spotted in Star Trek IV: The Voyage Home, where Scott wears uniforms with commander's insignia instead of captain's.
In an ultimately omitted line of dialogue from the final draft script of "Relics", Scott remarked, "Even starships are retired... some are just lucky enough to die in action."
Evidently, Scott was obliquely referred to in the final draft script of ENT: "Fallen Hero". A statement made by Charles Tucker III, regarding the warp reactor aboard Enterprise, was attributed to him in the scripted stage directions. The dialogue was, "I've given you all she's got, Captain! There's no more power!" A scene description about this section remarked, "His words foreshadow another fabled Starfleet engineer."
According to Star Trek II: Biographies, Scott was born in 31 August 2121 in Aberdeen, Scotland to parents Robert Burns Scott and Mary Darnley. He has a brother named James McNeil Scott and a sister named Mary Darnley Scott.
According to Who's Who in Star Trek 2, Scott was born in Glasgow, Scotland and has a sister named Fran. He spent a year working aboard the SS Deirdre before applying to Starfleet Academy. He became the Enterprise's chief engineer after the previous chief engineer Hoyt retired.
The short story Strange New Worlds VI names his mother Arlyne Jorgensen Scott and his sister Kristen Scott.
In the novel The Kobayashi Maru, Cadet Scott less-than-voluntarily entered the Command School at Starfleet Academy, but was reassigned to Engineering after a Kobayashi Maru attempt in which he defeated a Klingon squadron using a tactic which he knew the the computer would believe to be viable even though field testing that he had participated in had disproved the theory on which the tactic was based. His position as captain in the scenario was arranged by an instructor who knew that Scotty wanted to be in Engineering rather than Command to justify transferring Scotty to Engineering school.
In the D.C. Fontana novel Vulcan's Glory, in 2253, Lieutenant Scott signed aboard the Enterprise as a junior engineer under Lieutenant Commander Caitlin Barry. In his early days aboard the ship he set up a still in main engineering for producing Engine Room Hooch. Despite the popularity of the beverage, it was produced by an illegal still, and Scott along with the other engineers were warned never to produce the beverage again.
In the novel Enterprise: The First Adventure, by 2264, Scott assumed the responsibilities of being chief engineer and was promoted to lieutenant commander under the command of Captain James T. Kirk. Scott was fiercely loyal to Captain Christopher Pike and initially he did not warm up to Kirk as he felt that the young captain could place the ship in jeopardy. Over time, the two officers put their initial differences behind them and became close friends.
In the comic issue Retrospect, Scotty had an on-again, off-again relationship with a woman he'd known all his life named Glynnis Campbell (β). The comic tells the story of how they met and fell in love, went their separate ways, and eventually got married years later. They married shortly before the events of Star Trek II: The Wrath of Khan, and she died in a shuttle accident during the Enterprise crew's period of exile on Vulcan. The Star Trek: Department of Temporal Investigations novel Forgotten History gives her credit for inspiring him to grow a mustache.
The Star Trek novelization has Spock revealing that the Prime Scott was also stationed at Delta Vega, which Roberto Orci and Alex Kurtzman stated on the film's audio commentary were meant to be for the same reasons.
In the Starfleet Corps of Engineers novels, Scotty was given command of the unit sometime after his retrieval from the Jenolan.
In Star Trek Online, players encountered Scotty on Drozana Station in the year 2265, helping him protect the station from an infestation of Devidians. He plays a major role in the "Agents of Yesterday" expansion pack, in which he is voiced by James Doohan's son Christopher Doohan, who had previously played the role in the fan series Star Trek Continues.
