Throughout their travels in time and space, the Doctor took on and was called by a number of different aliases, titles and names. Some were fleeting. Others, like John Smith, were used by almost all of their incarnations. The Doctor told few individuals their real name. Instead, they asked others to call them simply, the Doctor.

The Doctor's real name Edit

As the Time Lord's true name was not generally known, "the Doctor", or "Doctor Who", became an alias and the exact reason for the Doctor to hide their true name is a complete mystery.

One account implied that their given name was ceremoniously withdrawn and stricken by their Cousins as punishment for a disgrace they brought upon their House. (PROSE: Lungbarrow)

Even when put on trial by the Time Lords, they were only referred to as "the Doctor", (TV: The War Games) although the Valeyard, a culmination of the Doctor's darker side who prosecuted the second trial, acknowledged that this was an alias. (TV: The Mysterious Planet) When the Fifth Doctor was officially inducted as Lord President, he declared that it was "out of the question" for him to be introduced by his true name, stating that he would accept being introduced as "Lord President Doctor". (AUDIO: Time in Office) Even those who had known them in childhood addressed them only as "the Doctor", such as the Master, (TV: Death in Heaven) and the Rani. (COMIC: Weapons of Past Destruction)

According to one account, during their 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) Another account implied that the Doctor's title had been chosen as a Gallifreyan custom, (TV: The Sound of Drums) and that he had been using it before he left Gallifrey. (TV: The Name of the Doctor, World Enough and Time)

The Doctor's real name has been said to be difficult to pronounce, for humans at least, (AUDIO: Slipback) and certainly for adults, (TV: Twice Upon a Time) possessing thirty eight syllables. (PROSE: Sleepy) The First Doctor once told an interrogator he "wouldn't be able to pronounce the first syllable of [his name]." (PROSE: Salvation) His seventh incarnation likewise told one of his captors that he "doubt[ed] [they]'d be able to pronounce the name [he] was originally given." (PROSE: Illegal Alien) When asked about the Doctor's name, Peri Brown once said that the Doctor had told her she would find it unpronounceable. (AUDIO: Slipback) Moments before his regeneration, however, the Twelfth Doctor stated his belief that "children [could] hear [his name]", but only when "their hearts [were] in the right place, and the stars [were] too." (TV: Twice Upon a Time)

The Doctor kept their true name hidden despite numerous "mind-probe" attempts and the effect of a truth field. (TV: The Girl in the Fireplace, The Time of the Doctor) 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," and that the Doctor was hiding his true name in 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)

Significance Edit

The Eleventh Doctor told Clara Oswald that his real name was not important since he specifically chose the title of "Doctor" to take its place, saying it was "like a promise you make." (TV: The Name of the Doctor) This promise was, as recited by the Tenth and War Doctors; "Never cruel or cowardly. Never give up, never give in." (TV: The Day of the Doctor) Even Clara considered "the Doctor" to be his true name and the only one that mattered. (TV: The Time of the Doctor) Despite their hatred of the War Doctor's actions, (TV: The Name of the Doctor) both the Tenth and Eleventh Doctors admitted "[he] was the Doctor more than [any of them]." (TV: The Day of the Doctor) When Clara was forced to take on his role for him, the Twelfth Doctor told her that "goodness has nothing to do with [being a Doctor]". (TV: Flatline)

The Doctor considered abandoning his name if he felt he had to do something highly immoral. (TV: The Beast Below, Face the Raven) The War Doctor rejected the name during the Time War, but proudly called himself the Doctor once he discovered the true outcome of the War. (TV: The Day of the Doctor) During his final days, the Twelfth Doctor stated being "the Doctor" was being kind, even if it meant doing complete foolish things like self-sacrifice, if it bought others a small amount of extra time to live. (TV: The Doctor Falls, Twice Upon a Time) The Thirteenth Doctor said that a "bit of adrenaline, dash of outrage and a hint of panic" helped her to remember who she was. (TV: The Woman Who Fell to Earth)

The 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 someone 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, such as in the Gamma Forests, it eventually came to mean "mighty warrior". (TV: A Good Man Goes to War) The Twelfth Doctor accepted he was "the original one" who "started it." (TV: The Return of Doctor Mysterio)

According to Dorium Maldovar, 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: "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. The Intelligence threatened to kill Clara Oswald and the Paternoster Gang 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)

The Doctor's real name became important during the Siege of Trenzalore, as it was the signal chosen by the Time Lords to come back to the universe, broadcasting the question "Doctor Who?" through a crack in reality, simultaneously broadcasting a Truth Field so that they could be sure that it was truly the Doctor responding to them. Despite this, when the Doctor was facing death, Clara told the Time Lords through the Crack that the only name of his that mattered was "the Doctor" and everything he stood for under that name, prompting them to give the Doctor a new regeneration cycle at the cost of closing the crack. (TV: The Time of the Doctor)

After meeting his twelfth incarnation, the First Doctor was confronted by the mysterious Testimony Foundation, who claimed that the Doctor was the "Doctor of War". Although the First Doctor initially feared this interpretation of his future, after witnessing his future self's efforts to save Captain Archibald Hamish Lethbridge-Stewart, he came to conclude that the "Doctor of War" was not a man who revelled in war, but a man who sought the moments of peace that existed amid open warfare, and who would always try to find another way to end war, and to find resolution, rather than resorting to bloodshed. (TV: Twice Upon a Time)

Ubiquity of the title Edit

The Doctor did possess at least one doctorate. (TV: The Moonbase, The Armageddon Factor, The Mysterious Planet) They sometimes described themselves as a "doctor of many things" (TV: Four to Doomsday) or of "everything". (TV: Spearhead from Space, Utopia) However, their knowledge was limited to anything prior to the Rassilon Era. (TV: Utopia) The Eleventh Doctor claimed that one of his doctorates was in cheesemaking, (TV: The God Complex) but only the "stinky, blue kind". (PROSE: Shroud of Sorrow)

On several occasions, the Doctor claimed they were not a medical doctor. (TV: "The Forest of Fear", "Mighty Kublai Khan") Though by their second incarnation, he had studied medicine in the 19th century, (TV: The Moonbase) although Clara recalled the Doctor telling her that he graduated in the wrong century. (TV: Death in Heaven) The Eleventh Doctor described himself as a medical doctor. (TV: The God Complex) The Seventh, Eleventh and Twelfth Doctors displayed some medical knowledge, being able to help with minor injuries (TV: Remembrance of the Daleks, The Vampires of Venice) and tell if a person was vitamin deficient. (TV: Thin Ice) The Ninth Doctor, remarking he "has [his] moments", could also diagnose patients in a hospital ward, quickly deducing they all shared the injuries of a scar on the back of their hands, collapsed chest cavities, crushed rib cages and gas masks fused into the flesh on their faces, (TV: The Empty Child) and displayed extensive knowledge on nanogenes, such as their ability to repair organic matter and restore life as a mere "quirk of matter". (TV: The Doctor Dances) The Tenth Doctor in particular proved a proficient medic, performing life-saving surgery on Laszlo, sustaining him as a Human-Pig hybrid, able to live as long as a human again. (TV: Evolution of the Daleks)

When asked by Mabli if her doctorate was in medicine, the Thirteenth Doctor described herself as having a doctorate in "medicine, science, engineering, candyfloss, Lego, philosophy, music, problems, people, [and] hope." (TV: The Tsuranga Conundrum)

Individuals with knowledge of his name Edit

Susan Foreman knew the Doctor's real name, and wrote it on the wrappings of a hypercube she sent to him after she had settled down on Earth. (PROSE: Ghost of Christmas Past)

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

The Eighth Doctor's companion, Samantha Jones, overheard his real name being said. She found it quite alien and virtually unpronounceable. (PROSE: Vanderdeken's Children)

When the Tenth Doctor first encountered her, River Song claimed to have known him at some point in his future, (TV: Silence in the Library) and, to prove her "credentials", she whispered his name in his ear, and apologised for having to do so. The Doctor was shocked at this, as "there [was] only one reason [he] would ever tell anyone [his] name, [and] only one time [he] could." (TV: Forest of the Dead) River indicated to Clara Oswald that she "made" the Doctor tell her his name and that "it took a lot of effort". (TV: The Name of the Doctor)

Near the end of his life, despite believing there was no one left in the universe who knew it, the Tenth Doctor encountered members of an unidentified pan-dimensional race that knew his real name. (AUDIO: The Last Voyage)

While separated from the Eleventh Doctor, Clara Oswald read his name in The History of the Time War. That timeline was later averted, however, leaving her with no memory of it, (TV: Journey to the Centre of the TARDIS) though she later began to recall certain moments of the timeline, (TV: The Name of the Doctor) and claimed to know the Doctor's name when bluffing to the Cybermen about being the Doctor. (TV: Death in Heaven)

Missy claimed to know the Doctor's real name from their time together on Gallifrey. She said it was "Doctor Who", and the Doctor had chosen it to be mysterious, but dropped the "Who" when he realised it was too on-the-nose. The Doctor said she was just teasing Bill, but he never answered if it was truly his name. (TV: World Enough and Time)

Commonly used aliases Edit

John Smith Edit

John Smith was an alias the Doctor frequently used on Earth and around humans when a "standard" name was needed, with the Eighth Doctor noting it was "the nom de guerre [he] seem[ed] to keep ending up with". (PROSE: Alien Bodies) 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) 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 First Doctor 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 & Bone Man's Story) The inspiration for the alias was John Smith of John Smith and the Common Men, with which he was familiar through Susan. (PROSE: The Witch Hunters)

In their second incarnation, the name was independently used by his companion Jamie McCrimmon while the Doctor was being treated for a concussion, as he saw it being used as a brand name on a metal container. (TV: The Wheel in Space) Likewise, Chang Lee chose to register the name for the Seventh Doctor while he was en route to get his bullet wounds healed. (TV: Doctor Who)

The Doctor adopted it on a semi-regular basis during their third incarnation while exiled on Earth, when he served as unpaid scientific advisor to UNIT. (TV: Spearhead from Space, Inferno, The Time Warrior)

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

Often, the Doctor would use variations of the name, like the online handle "jsmith", jsmith8", (PROSE: Blue Box, Lonely) the French variation "Jean Forgeron", (COMIC: The Forgotten) or the German translation "Johann Schmidt". (PROSE: The Shadow in the Glass, AUDIO: Storm Warning, et al.)

Doctor Who Edit

The name "Doctor Who" was applied to the Doctor on several occasions. When the First Doctor was using the name "Doctor Caligari" and someone remarked, "Doctor who?" he replied, "Yes, quite right." (TV: The Gunfighters) The computer WOTAN repeatedly referred to the First Doctor as "Doctor Who". (TV: The War Machines) Both Ian Chesterton and Vicki occasionally called the Doctor "Doctor Who". (PROSE: Doctor Who and the Zarbi)

Bessie's license plate during the Third Doctor's time at UNIT read WHO 1; (TV: Doctor Who and the Silurians) in the Doctor's seventh incarnation it read WHO 7, (TV: Battlefield) and WHO 8 in his eighth incarnation. (PROSE: The Dying Days) Miss Hawthorne referred to the Third Doctor as "the great wizard Qui Quae Quod"; those three words all mean "who" in Latin. (TV: The Dæmons) The aged Keeper of the Files referred to the Doctor with the name "Who". (PROSE: Doctor Who and the Doomsday Weapon)

The Fourth Doctor wrote a series of children's books during his time with UNIT which were mistakenly published under the name "Doctor Who": they were intended to be "The Doctor, Who Discovers Historical Mysteries", but the publishers presented it as "Doctor Who Discovers Historical Mysteries". (AUDIO: The Kingmaker) The Curator tapped his own nose when saying, "Who knows." (TV: The Day of the Doctor)

K9 was heard on occasion making playful remarks related to the Who name. (TV: A Girl's Best Friend, Invasion of the Bane) Clive Finch's website called him "Doctor Who". (TV: Rose) Upon reading the Tenth Doctor's mind, Reinette remarked that "Doctor Who" was "more than just a secret". (TV: The Girl in the Fireplace) The oldest question in the universe was "Doctor Who?" (TV: The Wedding of River Song)

The Master addressed a postcard to the Third Doctor as "Dr Who". (COMIC: Fogbound) Missy later told Bill Potts that the Doctor's real name was "Doctor Who", before correcting herself to say that he had picked it in his childhood as an attempt to be mysterious, but that he had dropped the "Who" because it was "too on-the-nose". The Twelfth Doctor told Bill she was just trying to wind her up. He later identified himself as "Doctor Who" to Jorj. (TV: World Enough and Time)

The version of the Doctor in the Land of Fiction was known as Dr. Who. (PROSE: Prelude Conundrum, Conundrum, Head Games)

Theta Sigma Edit

Theta Sigma, informally "Thete" and occasionally spelt "ΘΣ", was a nickname of the Doctor at the Time Lord Academy on Gallifrey. (TV: The Armageddon Factor, The Happiness Patrol; COMIC: Flashback) It identified him uniquely amongst the Time Lords and was not to be spoken outside of the Academy. (PROSE: Falls the Shadow)

K9 was improved by Time Lord Theta Sigma. (PROSE: K9 and the Beasts of Vega)

Theta Sigma was part of River Song's message to the Eleventh Doctor on the universe's oldest cliff-face. (TV: The Pandorica Opens)

When the Doctor's final incarnation permanently died during the first battle of the War in Heaven, his coffin had two Greek letters on it; one of these was "Sigma". (PROSE: Alien Bodies)

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)

Oncoming Storm Edit

The Doctor was referred to as the "Oncoming Storm" by the Draconians, (PROSE: Love and War) and in "the ancient legends of the Dalek homeworld". (TV: The Parting of the Ways) In Draconian, the title was pronounced "Karshtakavaar". (PROSE: Love and War) After being told of the title by the Ninth Doctor, (TV: The Parting of the Ways) Rose Tyler called the Tenth Doctor by the "Oncoming Storm" when she and Mickey Smith were being prepared for dissection by the Clockwork Droids. (TV: The Girl in the Fireplace)

The Tenth Doctor later introduced himself as the "Oncoming Storm" to a Dalek aboard of the Wayfarer, (PROSE: Prisoner of the Daleks) and referred to the title when confronting a rabbit he thought was a Zygon. (TV: The Day of the Doctor)

The Eleventh Doctor began calling himself the "Oncoming Storm" when he misinterpreted Sean's request to help the King's Arms football team "annihilate" another team at a match. (TV: The Lodger) He later referred to the title when the Daleks forgot him. (TV: Asylum of the Daleks)

As early as their second incarnation, the Doctor knew that the Daleks had also given them the epithet "Ka Faraq Gatri", (COMIC: Bringer of Darkness) which translated as "Destroyer of Worlds". (PROSE: Timewyrm: Revelation) or possibly "Nice guy, if you're a biped". (PROSE: Continuity Errors) He had been awarded the name upon orchestrating the destruction of the Dalek home planet Skaro in his seventh incarnation, (TV: Remembrance of the Daleks) though the Daleks also used it prior to Skaro's destruction. (COMIC: Bringer of Darkness) Davros also referred to the Doctor as "the Destroyer of Worlds" after the Meta-Crisis Tenth Doctor destroyed the New Dalek Empire on the Crucible. (TV: Journey's End)

Other Edit

Behind the scenes Edit

  • The first edition of the behind-the-scenes book The Making of Doctor Who, published in 1972, stated that the Doctor's name was "∂³∑x²". It was later spelt as "d³ᓬx²" in the "Who is the Doctor" prologue of Marvel Premiere #57 in 1980. This has never been confirmed in any Doctor Who narrative, but these letters do appear on the plinth in the Tomb of Rassilon in The Five Doctors. They are also seen on K9's regeneration unit in Regeneration.
    • The same first edition explained the Doctor "is never cowardly" which was expanded in the second edition to "never cruel or cowardly" and that "he never gives in, and he never gives up." These phrases were later used in the TV series as the promise the Doctor made when choosing his name.
  • Executive producer Steven Moffat jokingly said that no one can know the Doctor's name, except each successive showrunner. "We're commanded never to reveal what we have learned because then the show would have to be renamed Mildred. Oh, bugger."[2]
