Companion (Doctor Who) - History

History

When Doctor Who was created, the dramatic structure of the programme's cast was rather different from the hero-and-sidekick pattern that emerged later. Initially, the character of the Doctor was unclear, with uncertain motives and abilities. The protagonists were schoolteachers Ian Chesterton and Barbara Wright, who provided the audience's point-of-view in stories set in Earth's history and on alien worlds. Ian in particular served the role of the action hero. The fourth character was the Doctor's granddaughter Susan, who (though initially presented as an "unearthly child") was intended as an identification figure for younger viewers.

Carole Ann Ford, who played Susan Foreman, became unhappy with the lack of development for her character, and chose to leave in its second series. The character of Susan was married off to a freedom fighter and left behind to rebuild a Dalek-ravaged Earth. Doctor Who's producers replaced Susan with another young female character, Vicki. Similarly, when Ian and Barbara left, the "action hero" position was filled by astronaut Steven Taylor. This grouping of the Doctor, a young heroic male and an attractive young female became the programme's pattern throughout the 1960s.

When the programme changed to colour in 1970, its format changed: the Doctor was now Earth-bound, and acquired a supporting cast by his affiliation with the paramilitary organisation United Nations Intelligence Taskforce (UNIT). The Third Doctor, more active and physical than his predecessors, made the role of the "action hero" male companion redundant. In the 1970 season the Doctor was assisted by scientist Liz Shaw and Brigadier Lethbridge-Stewart, along with other UNIT personnel (such as Sergeant Benton). The intellectual Shaw was replaced by Jo Grant in the 1971 season, and as the programme returned to occasional adventures in outer space, the format shifted once more: while UNIT continued to provide a regular "home base" for Earth-bound stories, in stories on other planets the Doctor and Jo became a two-person team with a close, personal bond. This pattern, the Doctor with a single female companion, became a template from which subsequent episodes of Doctor Who rarely diverged. The "heroic male" type occasionally returned (for example, Harry Sullivan, Adric, Jack Harkness and Rory Williams), but the single female companion was Doctor Who's staple.

The character of Harry Sullivan was created by the production team when it was expected that the Fourth Doctor would be played by an older actor who would have trouble with the activity expressed by his predecessor. In the event, the Fourth Doctor part went to 40-year-old Tom Baker and the part of Harry, no longer required for the action role, was reduced.

In the final season for the Fourth Doctor, he acquired three companions (Adric, Tegan and Nyssa) and this situation continued under the Fifth Doctor for a while. Adric was written out by the unusual method within the series of being "killed off". By the Sixth Doctor, the Doctor was down to a single companion again.
