The character of the Doctor was created by the BBC's Head of Drama Sydney Newman

, a BBC staff writer who had been brought in to help develop the project. Webber's document contained a main character described as "The maturer man, 35–40, with some 'character twist'." However, Newman was not keen on this idea and — along with several other changes to Webber's initial format — created an alternative lead character named "Dr Who": a crotchety older man piloting a stolen time machine, on the run from his own far future world. No written record of Newman's conveyance of these ideas — believed to have taken place in April 1963 — exists, and the character of "Dr Who" first begins appearing in existing documentation from May of that year.

The Invasion of Time, the Fourth Doctor is asked to sign a document; although the signature itself is not directly seen on screen, his hand movements clearly indicate that he signs it with a question mark. A similar scene occurs with the Seventh Doctor in Remembrance of the Daleks.

It was mentioned by Tom Baker, the Fourth Doctor, during an interview with
The Age in 2003, that the Doctor is called so because he is "a doctor of time and relative dimension in space". Apart from being called a doctor of the TARDIS, the Doctor has also been referred to as just a "doctor of time travel".

The Second Doctor was intended to be a literally younger version of the First; biological time would turn back, and several hundred years would get taken off the Doctor's age, rejuvenating him.

 persona.

In contrast to the more flamboyant outfits of his predecessors, the Ninth Doctor wore a nondescript, worn black leather jacket, V-neck jumper and dark trousers. Eccleston stated that he felt that such definitive "costumes" were passé and that the character's trademark eccentricities should show through their actions and clever dialogue, not through gimmicky costumes. Despite this, there is a running joke about his character that the only piece of clothing he changes is his jumper, even when trying to "blend into" a historical era. The one exception, a photograph of him taken in 1912, wearing period gentleman's clothing, resembles the style of the Eighth Doctor.

Transitions

Save for the off-screen transition between the Eighth and Ninth Doctors, to date each regeneration has been worked into the continuing story. Also, most regenerations (save the Second-to-Third and Eighth-to-Ninth transitions) have been portrayed on-screen, in a symbolic handing over of the role. The following list details the manner of each regeneration:

  1. First Doctor (Hartnell): apparently succumbed to old age, steadily growing weaker throughout The Tenth Planet

In the original series, with the exception of the change from Troughton to Pertwee, regeneration usually occurred when the previous Doctor was near "death". The changeover from McCoy to McGann was handled differently, with the Doctor actually dying and being dead for quite some time before regeneration occurred. The Eighth Doctor comments at one point in the television movie that the anesthesia interfered with the regenerative process, and that he had been "dead too long", accounting for his initial amnesia

The 2005 series began with the Ninth Doctor already regenerated and fully stabilized, with no explanation given. In his first appearance in "Rose", the Doctor looked in a mirror and commented on the size of his ears, suggesting to some viewers that the regeneration may have happened shortly prior to the episode, or that he has not examined himself in the mirror recently. However, the Ninth Doctor's appearances in old photographs, without being accompanied by Rose, may also suggest that he had been regenerated for some time.

Davies revealed his reasoning that, after such a long hiatus, a regeneration in the first episode would not just be confusing for new viewers but also lack dramatic impact, as there would be no emotional investment in the character before he was replaced.

Eccleston stepped down from the role at the end of the 2005 series, and the Ninth Doctor regenerated into the Tenth in "The Parting of the Ways". It remains to be seen whether the Ninth Doctor will appear again, although Russell T Davies has stated that he does not intend to bring back former Doctors.

Continuity curiosities
Over the years, different writers and production teams have introduced their own twists to the Doctor's character, sometimes as part of a grand creative reinvention; others, out of narrative convenience or outside pressures. Without one driving vision to maintain continuity, newer details may occasionally seem to contradict earlier ones. Other details — sometimes significant ones — are later ignored, sometimes leading to argument amongst series fans as to how, or whether, these details apply in a broader context.

This idea was brought to the forefront in the '96 movie, where the Doctor states he is "half-human, on [his] mother's side", suggesting he had a normal human birth, rather than a synthetic Gallifreyan one. Madame de Pompadour's reference to the Doctor's lonely childhood in "The Girl in the Fireplace" would also seem to contradict the Loom theory. The 2007 episode "The Sound of Drums" also directly contradicts this, with Gallifreyan children leaving for the academy when they reach the age of 8. This episode also shows a young Master.
