Biography
After the Doctor was found guilty of breaking the Time Lord laws of non-interference and forced to regenerate, he began his third incarnation in exile on 20th century Earth. The Third Doctor immediately formed a working relationship with the British contingent of

to break the exile, and UNIT needed his expertise to combat the threats they encountered. There is some disagreement about when the Third Doctor's UNIT stories were set, with some evidence that they were contemporary stories set at the same time they were broadcast (the early 70s), and some evidence that they were set in the near future. According to the production team, there was an intention to set the stories in the near future, but the writers did not always remember this and set the stories in the present.
The Doctor also developed a good working relationship with

After meeting Jo, the Third Doctor encountered his greatest nemesis (next to the Daleks) —
the Master. A renegade Time Lord, the Master plagued the Third Doctor with his diabolical schemes, including the summoning of an ancient Dæmon, and unleashing the terrifyingly powerful Kronos, a Chronovore. The Doctor's exile continued until it was lifted by the Time Lords after he helped save them from destruction at the hands of Omega. The Third Doctor, free to roam space and time again, soon ran into the Master and an even older enemy —
the Daleks

Whilst facing the ecological destruction wrought by Global Chemicals and the super computer BOSS, Jo met and fell in love with Dr. Clifford Jones.

), he jumped at any chance to return to the stars. Though he had a somewhat patrician and authoritarian air, he was quick to criticise authority, and often exclaimed "Now ''listen'' to me!" when dealing with people seeking to obstruct him.

companions in a paternal fashion, and even held a thinly veiled but grudging admiration for his nemesis,
the Master, and for UNIT's leader,

, with whom he eventually became friends. In fact, even when his much-resented exile was lifted, the moral and dashing Third Doctor continued to help UNIT protect the Earth from all manner of alien threats, a role that continued into his future incarnations.
In general, this incarnation of the Doctor was more physically daring than the previous two and was the first to confront an enemy physically if cornered (both of his previous incarnations nearly always attempted to dodge, flee or negotiate rather than attack). This often took the form of quick strikes, with the occasional joint lock or throw — usually enough to get himself and anyone accompanying him out of immediate danger, but usually not to the extent of a brawl, in keeping with the Doctor's non-violent nature. He only used his fighting skills if he had no alternative, and even then generally disarmed his opponents rather than knocking them unconscious. Indeed, his martial prowess was such that a single, sudden strike was usually enough to halt whatever threatened him, and at one point he reminded
Captain Yates of UNIT (physically as well as verbally) that Yates would have a difficult time removing him from somewhere when he did not want to be removed (''
The Mind of Evil'').
The Third Doctor was a skilled diplomat (keeping talks going in ''
The Curse of Peladon,'' for example) and linguist, as well as having a penchant for disguises.

Barry Leopold Letts (26 March 1925 – 9 October 2009) was an English actor, television director, writer and producer, best known for being the producer of ''Doctor Who'' from 1969 to 1974.
Born in Leicester, he worked as an actor in theatre, ...
. Through the first season, he wore a flowing, crimson or red lined cape (which he alternated) over a very dark blue velvet
smoking jacket (which often looked black in certain lighting) and a ruffled shirt with a variety of neckties such as
jabots,
bow ties or
cravats. Beginning in the 1971 season, when the look was refashioned by Ken Trew, Pertwee alternated between the dark blue, red or green jacket and a cloak with purple lining, although sometimes the red lining cloak would be used. In the final two seasons, the colour scheme changed from story to story, though the basic look was maintained.
In his first episode, when the Doctor evades capture by taking a shower, a tattoo of a serpent can be seen on his arm. Whereas Pertwee obtained it during his service in the

Title sequence and logo

The original title sequence for the Third Doctor's seasons introduced colour and was an extension of the "howlaround" kaleidoscopic patterns used for the previous Doctors.
It features red, black then green flaming hands, then shows Jon Pertwee's face followed by a series of swirling lines to represent the time vortex. As the vortex turns red it speeds up only to start reversing, and in some cases it is seen turning pink and yellow. In the Third Doctor's final season, a new title sequence was introduced using a full-body picture of Pertwee, designed by Bernard Lodge. Partially inspired by the
slit-scan hyperspace sequence in Stanley Kubrick's ''
2001: A Space Odyssey'', one portion of this sequence is the prototype for the time tunnel sequence of the Fourth Doctor's seasons. The Third Doctor's final season also introduced the diamond logo
which would remain in use until 1980 and be revived in 2022.
The series logo introduced in 1970 and used for the first four seasons of Pertwee's tenure would later be used again, in modified form, as the logo for the
1996 Doctor Who TV movie. This version subsequently became the official ''Doctor Who'' logo, most notably with regards to products connected to the
