Aliases of the Doctor

This article needs a big cleanup.

per Forum:Notable Aliases article needs editing to remove content and shape into an article, rather than list of names. + Many references are doubled in the "Minor aliases" and "Aliased given by others"

These problems might be so great that the article's factual accuracy has been compromised. Talk about it here or check the revision history or Manual of Style for more information.

Throughout his travels in time and space, the Doctor took and was called by a number of different aliases, titles and names. Some were fleeting. Others, for example John Smith, were used by almost all of his incarnations. The Doctor told few individuals his real name. Instead, he asked others to call him the Doctor.

The Doctor's real name

Ubiquity of the title

"The Doctor" was not a name, but a title. His true name was not generally known, and "the Doctor" became an alias. It has been implied his given name was ceremoniously withdrawn and stricken by his Cousins as punishment for a disgrace he visited upon his House. (PROSE: Lungbarrow)

The Doctor's real name has been said to be difficult to pronounce, for humans at least. He once told an interrogator (when asked his name): "you wouldn't be able to pronounce the first syllable of it." (PROSE: Salvation)

Even when he was twice put on trial by his own people, the Time Lords, he was only referred to as "the Doctor" (TV: The War Games), although the Valeyard, who prosecuted the second trial (and who himself was a culmination of the dark side of a future incarnation of the Doctor) acknowledged that it was an alias. (TV: The Trial of a Time Lord) However, as the Doctor chose that "name" as a Gallifreyan custom (TV: The Sound of Drums), its use in an official capacity is not exceptional. The Doctor kept his true name hidden despite numerous "mind-probe" attempts, voluntary (TV: The Lodger) and involuntary (TV: The Girl in the Fireplace, The Shakespeare Code)

Individuals with knowledge of his name

When the Tenth Doctor first encountered her, River Song claimed to have known him at some point in his future. She was one of the few individuals confirmed to know his true name. To win the Doctor's trust and prove her "credentials", she whispered his name in his ear, and apologised for having to do so. The Doctor seemed shocked at this, later saying to her, "There is only one reason I would ever tell anyone my name, only one time I could." (TV: Forest of the Dead)

She whispered the Doctor's name for a duration of roughly two seconds, suggesting the name may only be a few syllables long (assuming she uttered a complete name). Steven Moffat made a point of mentioning that he always felt the Doctor's name was never revealed only because it must have been some "terrible secret".

When asked about the Sixth Doctor's name, his companion Peri Brown once said that the Doctor had told her she would find it unpronounceable. (AUDIO: Slipback)

The Sixth Doctor told Becky his name. (PROSE: Teach Yourself Ballroom Dancing)

The Eighth Doctor's companion Samantha Jones was told his real name. She found it quite alien and virtually unpronounceable. (PROSE: Unnatural History, Vanderdeken's Children)

When the Doctor spoke his real name aloud in the novel Vanderdeken's Children it was not written in the prose, but represented by "—" instead.

Near the end of his tenth incarnation, members of an unidentified pan-dimensional race came to know the Doctor's real name. At this point he was of the opinion there was no one left in the universe who knew it. (AUDIO: The Last Voyage)

Clara Oswald read his name in The History of the Time War. That time line was later averted however, leaving her with no memory of it. (TV: Journey to the Centre of the TARDIS) Later, when exposed to forces deep within a future version of the dying TARDIS, she began to regain some of those memories. (TV: The Name of the Doctor)

True name

The Carrionite Lilith, unable to discover the Tenth Doctor's true name even with the "witchcraft" used by her kind, remarked, "There is no name. Why would a man hide his title in such despair?" (TV: The Shakespeare Code) The psychically-gifted Evelina, who attempted to foretell the Doctor's future, remarked that his "true name" was "hidden" from her. (TV: The Fires of Pompeii)

The Eleventh Doctor once joked that his middle name was 'Bad Penny', and that he received strange looks when filling in forms. (TV: The God Complex)

According to Dorium Maldovar after his beheading, the religious organisation the Silence had a particular interest in the Doctor's name. He explained that if the Doctor lived long enough, on the fields of Trenzalore, at the fall of the Eleventh, when no creature could speak falsely or fail to answer, a question that must never be answered would be asked: the first question, hidden in plain sight. The question was simply: "Doctor Who?". The Silence wanted to stop the Doctor from revealing his true name. (TV: The Wedding of River Song) The Doctor was at a later time forced to go to Trenzalore to rescue his friends from the Great Intelligence, which sought to gain access to the Doctor's tomb. The tomb, which was a future version of his own dying TARDIS, would open only to the Doctor's real name. Threatening to kill the Doctor's friends if he did not speak his name and open the tomb, the situation was resolved when the data ghost of River Song was able to silently transmit his name to the TARDIS, thus opening the door for the Great Intelligence. (TV: The Name of the Doctor )

Eventually, the Doctor held a book called The History of the Time War in his TARDIS library, unfolding the history of the Last Great Time War and apparently, containing his name. (TV: Journey to the Centre of the TARDIS)

Significance

The Eleventh Doctor told Clara Oswald that his real name was not so important, since he specifically chose in its place the title of "Doctor", "like a promise you make." (TV: The Name of the Doctor) This promise was, as the Tenth and War Doctors recited together, "Never cruel or cowardly. Never give up, never give in." (TV: The Day of the Doctor)

The Saxon Master knew of this and implied that the Doctor's title had been chosen because it meant "the man who makes people better", although he found the choice "sanctimonious" for some one who ended millions of lives and ruined many others. (TV: The Sound of Drums) River Song was aware of this contradiction in the Doctor's behaviour: she said that the Doctor was the first to have this title and that the rest of the universe later adopted it, usually to mean 'healer' or 'wise man'; however, she added, in some parts of the universe (eg. the Gamma Forests), it eventually came to mean 'mighty warrior'. (TV: A Good Man Goes to War)

Far from being a randomly chosen title or one intended to inflate his credentials, the Doctor did possess at least one doctorate. (TV: The Moonbase, The Armageddon Factor, The Mysterious Planet) He sometimes described himself as a "Doctor of many things" (TV: Four to Doomsday) or "everything". (TV: Utopia) Exactly what his doctorate(s) were for remain a mystery, but on several occasions the Doctor stated he was not a medical doctor. (TV: "The Forest of Fear", "Mighty Kublai Khan", AUDIO: Red Dawn) That didn't stop his second, third, tenth and eleventh incarnations from sporting a stethoscope on occasion. (TV: The Runaway Bride, Partners in Crime, Planet of the Ood, Planet of the Dead, The Doctor's Daughter, The Lodger, etc) The Doctor did note that by his second incarnation, he had studied medicine in the 19th century. (TV: The Moonbase) He also claimed one of his doctorates was in cheese making. (TV: The God Complex)

Common aliases

During his life, numerous names, titles and epiphets were either used by or bestowed upon the Time Lord most widely known as the Doctor.

The Doctor

As noted above, the Doctor itself was an alias, despite it being the title by which the Time Lord was most widely known. It has been claimed that, as a Gallifreyan custom, he chose this alias himself. (TV: The Sound of Drums) On one occasion, a human knew this name without the Doctor saying it out loud. (PROSE: Cat's Cradle: Warhead) His other aliases often included the title "Doctor". (TV: Spearhead from Space) He implied to Peri his given name also began with such a title. (TV: The Mysterious Planet) Drax, a fellow Time Lord, indicated the Doctor did indeed possess a doctorate (although in what was not indicated). (TV: The Armageddon Factor) According to one account, during his first incarnation, the Doctor adopted this name in dealing with human colonists on the planet Iwa at the same time that his granddaughter adopted the name "Susan". (PROSE: Frayed) According to another account, the Doctor and Susan already went by these names when they left Gallifrey. (AUDIO: The Beginning)

During his eleventh incarnation, the Doctor claimed that he didn't actually know why he and other people called him 'the Doctor'. (TV: The Lodger)

John Smith

John Smith was an alias the Doctor would frequently use on Earth and around humans when a "standard" name was needed. It was often preceded by the title "Doctor", though not always - for example, when he was undercover as a teacher at a school or a patient in a hospital. (TV: School Reunion, Smith and Jones) The earliest known use occurred during his first incarnation, when he used a library card with the name Dr. J. Smith while living at 76 Totter's Lane, (TV: The Vampires of Venice) as well as for identification when renting the junkyard. (PROSE: The Rag and Bone Man's Story) The inspiration for the alias was John Smith of John Smith and the Common Men, which he was familiar with through Susan. (PROSE: The Witch Hunters) In his second incarnation, the name was independently used by his companion Jamie McCrimmon (who would not have known of the Doctor's earlier use of the name) while the Doctor was being treated for concussion, as he saw it being used as a brand name on a metal container. (TV: The Wheel in Space) Later, he adopted it on a semi-regular basis during his third incarnation while exiled on Earth, when he served as unpaid scientific advisor to UNIT. (TV: Spearhead from Space, et al)

As "John Smith" was considered a generic name in some Earth cultures, the Doctor's use of the alias was occasionally treated with scepticism. (TV: Midnight)

The Doctor twice changed himself into a human who used the name John Smith. This occurred in his seventh incarnation (PROSE: Human Nature) and in his tenth (TV: Human Nature/The Family of Blood).

• A German variation of this name, "Johann Schmidt," was used by the Sixth Doctor when he infiltrated the Third Reich to investigate the origins of the Fourth Reich that was currently active in 2001, creating fake credentials establishing him as Major-General Johann Schmidt of the Berlin Fifth Medical Corps (PROSE: The Shadow in the Glass). The Seventh Doctor also used this name while impersonating the Reichsinspektor General (PROSE: Timewyrm: Exodus), while the Eighth Doctor used it while posing as a German spy. (AUDIO: Storm Warning) An alternative version of the Eighth Doctor who existed in a timeline where the Nazis won World War II, also used the name. (AUDIO: Colditz, Klein's Story) The Eleventh Doctor took the place of a real Dr. Schmidt when his psychic paper displayed the credentials of a visitor expected at the Lexington Bank. (PROSE: Borrowed Time)
• A French variation, "Jean Forgeron," was used by the Fourth Doctor when met by French soldiers in the labyrinth underneath Paris. (COMIC: The Forgotten)
• Given to him coincidentally by Chang Lee on his hospital admittance forms after he was shot near the end of his seventh incarnation. (TV: Doctor Who)

He was personally known to Abraham Lincoln by this name after he had saved the president's life during an assassination attempt in Richmond, Virginia. (PROSE: Blood and Hope)
• While impersonating a health and safety officer during an investigation of Adipose Industries. (TV: Partners in Crime)

• The Doctor introduced himself as Mr Smith, and Clara as his wife. (TV: The Crimson Horror)

Theta Sigma

Theta Sigma (ΘΣ), informally Thete, was a nickname of the Doctor at the Time Lord Academy on Gallifrey. (TV: The Armageddon Factor, The Happiness Patrol, COMIC: Flashback)

In an alternative timeline in which Rassilon failed to finish the Eye of Harmony before his death, the Doctor never left Gallifrey and became a commentator rather than a renegade Time Lord. He was known as Commentator Theta Sigma. (AUDIO: Forever)

Theta Sigma is also seen in River Song's message to the Doctor on the Universe's oldest cliff-face. (TV: The Pandorica Opens)

Doctor Who

The name Doctor Who was applied to the Doctor, intentionally or unintentionally, on many occasions.

• The computer WOTAN referred to the Doctor as Doctor Who. (TV: The War Machines)
• The Second Doctor once signed a message as "Dr W." (TV: The Underwater Menace)
• K9 was heard on occasion making playful remarks related to the Who name. (TV: A Girl's Best Friend, TV: Invasion of the Bane)
• The Third Doctor wrote a series of children's books during his time with UNIT which were mistakenly published under this name. (AUDIO: The Kingmaker)

The name was often unintentionally invoked when characters wished to learn who the Doctor was and what his name was: "Doctor? Doctor who?" Often this is done for comic effect; see The "Doctor Who?" running joke.
