Montgomery Scott
Captain Montgomery Scott – often referred to as "Scotty" by his shipmates – was a male Human Starfleet officer who lived during the 23rd and 24th centuries.

For a period of nearly thirty years, he served as the chief engineer of both the  and the , both under the command of Captain James T. Kirk. (; ; , et al.) With his reputation as a "miracle worker", he was a man of superior technical and engineering skill, experience, and ingenuity. (; , ; )

Early life and career 
Montgomery Scott was born in Scotland on Earth in 2222. () He spent part of his life in Aberdeen, once referring to himself as an "old Aberdeen pub-crawler." () After having time travelled to 1986, Scott was introduced in a cover story as being from Edinburgh. () Upon being asked how he adjusted to space travel, Scott once admitted, "I was practically born to it." ()

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. () Upon joining Starfleet, his serial number was SE 19754 T. ()

Over his career, Scott had experience working with PXK pergium reactors. The last time he had even seen one was in 2247, that was, until he attempted to repair the reactor at the Janus VI colony twenty years later. () For a time in his career, he had also served as an engineering advisor for the freighting-line base established in the Deneva system that operated between the Deneva colony and the outlying asteroid belts. () 
 
During the course of his career, Scott wrote several technical manuals, including one titled Operating Protocol - Flow Sensors. A copy of this manual was stored in the Engineering Systems Database aboard the  in 2366. () 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. ()

The five-year mission 

By 2265, Scott was assigned to the  where he served as chief engineer under Captain James Kirk. () The Enterprise was the first ship on which he was the chief engineer. ()

His duties also included maintenance and operation of the Enterprises transporter systems. Three of his top engineers included Lieutenants Kyle, Leslie, and Gabler. He was understandably upset when , 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. (; ) 

Scott also served as the ship's second officer, and often assumed command when both Kirk and Spock left the ship, or they both were incapacitated. Thus, he often faced critical diplomatic and military situations. () 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. () 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. () Despite being a capable command officer he never pursued his own command post because he "...never wanted to be anythin' else but an engineer." ()

By the late 2260s, Scott knew more about the warp engines aboard a  starship than even the men who designed them. () Furthermore, Scott was diligent in keeping his professional skills up to date considering he was an avid reader of technical journals, which he considered his idea of relaxing. () 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. (; ) As he said to Geordi La Forge in the 24th Century, "A good engineer needs to be a wee bit conservative, at least on paper." 

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. ()

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. ()

Later in 2267, Scott was thrown against a bulkhead of the Enterprise during an explosion caused by a female crewmember. 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 . 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. (; )

[[File:Scott explains that it's green.jpg|thumb|left|"Well, it's green."]]

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 a 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  where they would be "no tribble at all". ()

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. ()

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. ()

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. () 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. ()

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. ()

Scott 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. ()

Scott complained to Kirk that "one of those barefoot whaddyacallems" had entered Engineering and "tried to incite my crew to disaffect". ()

In 2268, Scott 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!" ()

 Later career 

In 2270, Commander Scott played an instrumental role in the massive refit of the USS Enterprise while serving under Captain Will Decker. ()

In  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. ()

With the Enterprise safely at , Scott was promoted to captain and reassigned to the  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 Lawrence H. 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  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 Enterprises 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". (; )

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. () For three weeks, after a shakedown cruise, the flaws in the starship's systems were being identified and repaired under the supervision of Scott. ()

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. ()

 Retirement 
In 2293, Scott obtained a boat in anticipation of his retirement from the Enterprise-A. ()

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  , 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". ()

In 2294, following his retirement from Starfleet, Scott traveled aboard the  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 Ensign Matt Franklin were the only survivors. Knowing that they didn't have enough supplies to wait for the ship's distress call to be picked up, Scott rigged the Jenolans transporter systems, and existed for 75 years in the ship's transporter buffer. ()

In 2369, Montgomery Scott was rescued by the , but due to phase inducer failure, 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 Enterprises shuttlecraft Goddard. ()

Sometime before 2387, Montgomery Scott discovered the necessary formulas enabling transwarp beaming, which Spock later gave to  in 2258 of the alternate reality. ()

 Family and personal life 
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  in a surprise attack by Khan Noonien Singh. Scott was grief-stricken after the tragedy. ()

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." (; ) He considered Scotch a drink for real men as opposed to, for instance, vodka which he referred to as "sodapop" and "milk diet". (). He did not like synthehol Scotch. ()

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, () an arrest for murder on Argelius, () and a "wee bout" requiring Dr. McCoy's attention. ()

He wore his Scottish Clan kilt on three occasions. ( and ) He also played bagpipes, most notably playing "Amazing Grace" at the funeral for Captain Spock in 2285. () He was also fascinated to be handling an old-fashioned Scottish claymore. ()

 Friendships 
Despite his superior talents as an engineer, he was often the source of comic relief among the Enterprise crew, due to his use of the Scots language. (; ; )

 Romantic relationships 
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. 

Scott was first attracted to Carolyn Palamas and reacted bitterly to the Greek god Apollo's infatuation with her. ()

While under the influence of Harry Mudd's love potion crystals, Scott briefly became interested in M'Ress. After the effects wore off, he snapped at her during his hangover. ()

Scott later became infatuated with the newly transferred Mira Romaine in 2269. ()

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. ()

 Holograms  

During Dal's many attempts at the , he requested that the computer select a new chief engineer for the recently departed Jankom Pog. He was given a holographic Scotty as a replacement. Scott was the rank of captain and appeared as he did during the early 2290s. ()

 Background information 
Montgomery Scott was played by actor James Doohan in all of the character's television and cinematic appearances set in the "prime" universe. An alternate timeline version of Scott was voiced by Matthew Wolf in .

The character of Montgomery Scott mostly originated from James Doohan himself. Doohan was asked by Director James Goldstone, to whom he had auditioned for another role only ten days prior, to come in and read a few lines from the script of  for him, Gene Roddenberry, Robert Justman, Joseph D'Agosta, and Morris Chapnick. The role he was proposed for was an unnamed Chief Engineer. When Goldstone asked him to do some accents, 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)

NBC's early- press brochure about Star Trek described Scott thus: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)

In the final draft script of  (dated ), Scott was described as "40... very military type." This suggests he was born in 2226.

Although Scott does not appear in "The Menagerie, Part II", he did feature in the script for that episode. At the end of the teaser, he accompanied McCoy into the Enterprises hearing room, without having any lines of dialogue, eager to help Captain Kirk but unable to. Then, when the hearing-room screen abruptly came on in the first act of the script, Scott was ordered, by a Talosian projection of Commodore Mendez, to turn the screen off. Despite trying to do so with a remote control, he found that the screen wouldn't go off. Scott also appeared in a deleted scene from "The Menagerie, Part II". In it, after again accompanying McCoy into the hearing room, he announced that, thanks to McCoy, they had managed to determine which computers Spock had jammed in order to lock the ship on a course to Talos IV. As Scott explained, this discovery would allow the Enterprise officers to "safely cross-circuit that series out, return the vessel to manual control." 

The series writer's guide (third revision, dated ) described Scott thus: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 , 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 , when Scott is holding a bag of food. There is also a scene in  in which his missing digit is briefly seen as he holds a giant armful of tribbles.

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 . 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 "". 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 Scott's  in 's  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  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  was filmed after "Relics", causing a . (In what may have been an attempt to address the discrepancy, in the  , Guinan tells Chekov that Kirk is, in fact, alive within the Nexus, though this information may not have reached Scott.) 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. ()

Another minor inconsistency could be spotted in , 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 . 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."

In the unfilmed Star Trek: The First Adventure script, Scott was depicted as working with George Kirk on an experimental dilithium-fuelled warp jump before his disappearance.

Apocrypha 
The nineteenth issue of the IDW comics series Star Trek: Ongoing reveals the alternate reality Scott's full name to be Montgomery Christopher Jorgensen Scott. Since Scott was born before the timeline split, he would therefore have the same full name in the prime universe.

With the introduction of Scott's origin story in the alternate reality, several novels set in the prime reality detail Scott's origins there:

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 Enterprises chief engineer after the previous chief engineer Hoyt retired.

The short story Bum Radish: Five Spins on a Turquoise Reindeer names his mother Arlyne Jorgensen Scott and his sister Kristen Scott.

The video game Star Trek: Starship Creator gives his parents' names as Mary and Vaughn Scott. His sister is named Linda Preston.

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 Scott wanted to be in Engineering rather than Command to justify transferring Scott 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.

The crew fought off an attempt by former DaiMon Bok of the Ferengi to hijack the Intrepid and use it to time travel and prevent his son from being killed by Captain Picard and solved the Intrepid mystery by discovering a powerful lifeform capable of traveling easily between galaxies and drawing starships with it.

As the Challenger exploded, he set the transporter to potentially send himself to safety. His current fate is unknown.
