Aliases of the Doctor

Throughout his travels in time and space, the Doctor employed many different aliases, titles and epiphets. Some of these were fleeting. Others, for example John Smith, were used by almost all of his incarnations. The Doctor told few individuals his real name, causing others to give him names such as The Doctor.

Ubiquity of the title
"The Doctor" was not a name, but was, in fact, a title. His true name was not generally known, and as such the very title "the Doctor" was 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 It has been implied his given name was ceremoniously withdrawn and stricken by his Cousins, as punishment for a disgrace he visited upon his House. (NA: Lungbarrow)

When asked about the Sixth Doctor's name, his companion Peri Brown once said that she had been told it, but she couldn't pronounce it. (BBCR: Slipback) Similarly he once told an interrogator (when being asked his name): "you wouldn't be able to pronounce the first syllable of it." (PDA: Salvation)

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

Individuals with knowledge of his name
The Master knew the Doctor since their Prydon Academy days, and by one account even earlier (BFA: Master), but it is not known for certain whether he ever knew the Doctor's true name, although he was well aware that "the Doctor" was an alias. (DW: The Sound of Drums)

Another classmate of the Doctor's, Drax, may have known his real name, but instead referred to the Doctor by the nickname "Thete", short for Theta Sigma. (DW: The Armageddon Factor; The Happiness Patrol)

Madame de Pompadour recognized it as an alias when she was briefly connected to the Doctor's mind, saying "Doctor...Doctor who? It's more than just a secret, isn't it?". (DW: The Girl in the Fireplace)
 * Whether or not Madame de Pompadour actually learned his name this way remains undisclosed. She was able to see into his mind and into his past, although it was established that if mind-reading was done in this way, memories could be closed off at will. That said, the Doctor was not aware that she was reading his mind at the time.

River Song, who when the Tenth Doctor first encountered her, claimed to have known him at some point in his future, is one of the few individuals confirmed to know his true name. In order to win the Doctor's trust, and prove her "credentials", she was seen to whisper the name into his ear. The Doctor seemed particularly shocked at this, later saying to her "there is only one reason I would ever tell anyone my name, only one time I could." (DW: 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".

At least one other person, the Eighth Doctor's companion Samantha Jones, was also told his real name. She found it quite alien and virtually unpronounceable. (EDA: 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 "&mdash;" 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. (BBCR: The Last Voyage)

To date there have been at least two individuals who received intimate knowledge of the Doctor's life and history -- Jackson Lake (DW: The Next Doctor) and Craig Owens (DW: The Lodger). There is no indication that this information, received via a data recording device for the former and the latter via the Doctor himself, included knowledge of his real name.

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?" (DW: The Shakespeare Code) The psychically-gifted Evelina, who attempted to foretell the Doctor's future, remarked that his "true name" was in fact "hidden". (DW: The Fires of Pompeii)

Significance
Far from being a random title, or one intended to inflate his credentials, the Doctor did, indeed, possess at least one doctorate. (DW: The Moonbase, The Armageddon Factor, The Mysterious Planet) On other occasions he described himself as a "Doctor of many things" (DW: Four to Doomsday), or, indeed, "everything". (DW: Utopia) Exactly what his doctorate(s) were for remain a mystery, but on several occasions the Doctor stated he was not a medical doctor, though that didn't stop his second, third, tenth and eleventh incarnations from sporting a stethoscope on occasion. However the Doctor noted that he had studied medicine in the 19th century. (DW: The Moonbase)

List of 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 name by which the Time Lord was most widely known. It has been claimed that, as per Gallifreyan custom, he chose this alias himself (DW: The Sound of Drums), though it may have just been a misunderstanding caused by an earlier alias. (see Names given by others.) On at least one occasion, a Human knew this name without the Doctor even saying it out loud. (NA: Cat's Cradle: Warhead) His other aliases often included the title "Doctor". He implied to Peri that his given name also began with such a title. (DW: The Mysterious Planet) Drax, a fellow Time Lord, indicated that the Doctor did indeed possess a doctorate (although in what is not indicated). (DW: The Armageddon Factor) According to one account, during his first incarnation, the Doctor adopted this name for the benefit of Human colonists on the planet Iwa at the same time that his grand-daughter adopted the name "Susan". (TN: Frayed)

During his eleventh incarnation, the Doctor claimed that he didn't actually know why he and other people called him 'The Doctor'. (DW: The Lodger) This may have been in an attempt to prevent Craig from asking why they call him the Doctor. This would have been hard to explain to him.

John Smith
John Smith was the alias the Doctor often used on Earth and around Humans when a "standard" name was often required or demanded. It was usually preceded by the title "Doctor", though not always - for example, when he worked undercover as a teacher at a school and as a patient in a hospital. (DW: School Reunion, Smith and Jones) The earliest known use of the name occurred during his first incarnation, when he used a library card with the name Dr. J. Smith while still living at 76 Totter's Lane (DW: The Vampires of Venice), as well as for identification when renting the junkyard (ST: The Rag and Bone Man's Story) 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). (DW: 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. (DW: Spearhead from Space, et al)

As "John Smith" is considered a very generic name in some Earth cultures, the Doctor's use of the alias was occasionally treated with skepticism by others. (DW: Midnight)

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

(TN: Blood and Hope)
 * Used while impersonating a health and safety officer during an investigation of Adipose Industries (DW: Partners in Crime)
 * The Tenth Doctor attempted to use the alias aboard the Crusader 50 bus on the planet Midnight, but it was recognized as a false name and rejected by the panicking humans aboard. (DW: Midnight)

 * Used when encountering Jackson Lake, a man who, due to Infostamp exposure, believed himself to be an incarnation of the Doctor. (DW: The Next Doctor)
 * Used by the Doctor while posing as his Ganger counterpart. (DW: The Almost People)

Theta Sigma
Theta Sigma (ΘΣ), informally Thete, was a nickname used by the Doctor during his years at the Time Lord Academy on the planet Gallifrey. (DW: The Armageddon Factor, The Happiness Patrol, DWM: Flashback) The name might also have been a codename used by some aspects of Time Lord government to refer to the Doctor. (The Adventures of K9 series)

River Song used the written form "ΘΣ" on a message to the eleventh Doctor on Planet One, though the Doctor specifically called these and other apparently Greek numbers on the cliff face "co-ordinates". (DW: The Pandorica Opens)


 * "ΘΣ" was also a commonly-used abbreviation for "God" in Greek manuscripts of the New Testament. The capital letters Theta and Sigma together resemble the word "ΟΣ", (who), and some scribal variations in New Testament texts will have "ΟΣ" in a few passages while others have "ΘΣ" in the same passages.

Names given by others
A list of name other individuals have called the Doctor throughout his travels.
 * The Doctor: While later accounts contradict this, Barbara Wright and Ian Chesterton seem to have (albeit unintentionally) given him this title, after being informed that his alias of "Doctor Foreman" was not his real name and having been given no other alternative name by which to call him (DW: An Unearthly Child). The Doctor does not protest and, by the end of the sixties, starts introducing himself by this name.
 * Doc: On rare occasions individuals (such as Steven Taylor, Peri Brown, Jack Harkness, Jimmy Stalkingwolf) referred to the Doctor as "Doc", usually earning a rebuke from the Doctor.

(DW: Rose) K9 was heard on occasion making playful remarks related to the Who name. (KAC: A Girl's Best Friend, SJA: Invasion of the Bane) It is unclear whether the Doctor himself ever actually used the name, although his third incarnation drove an automobile with the licence number "WHO 1" (DW: Doctor Who and the Silurians, et al) and not long before his regeneration was seen driving a futuristic vehicle that possibly apocryphal sources suggest may have been called the Whomobile. (DW: Invasion of the Dinosaurs) The Doctor wrote a series of children's books during his time with UNIT which were mistakenly published under this name. (BFA: The Kingmaker)

First Doctor

 * The Traveller from Beyond Time: The name given to the Doctor by the Elders. (DW: The Savages)
