Fourth Doctor

The Fourth Doctor is the fourth incarnation of the protagonist of the long-running BBC television science fiction series Doctor Who.

He was portrayed by Tom Baker for seven consecutive seasons from December 28, 1974 (Part One of Robot) to March 21, 1981 (Part 4 of Logopolis), and remains the longest-lived incarnation of the Doctor in the show's on-screen history, counting both the classic and modern series.

Within the series' narrative, the Doctor is a centuries-old Time Lord alien from the planet Gallifrey who travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body, changing his physical appearance and personality in the process.

Famous quotes containing the words fourth and/or doctor:

    The British are a self-distrustful, diffident people, agreeing with alacrity that they are neither successful nor clever, and only modestly claiming that they have a keener sense of humour, more robust common sense, and greater staying power as a nation than all the rest of the world put together.
    —Quoted in Fourth Leaders from the Times (1950)

    It seems to me that your doctor [Tronchin] is more of a philosopher than a physician. As for me, I much prefer a doctor who is an optimist and who gives me remedies that will improve my health. Philosophical consolations are, after all, useless against real ailments. I know only two kinds of sickness—physical and moral: all the others are purely in the imagination.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
