At twenty-six years old, Purves first became known to television audiences in 1965 as Steven Taylor, one of the early time-travelling companions in the programme "Doctor Who", when the Doctor was played by William Hartnell. He has provided DVD commentaries for many of the surviving "Doctor Who" episodes he appeared in and documents the making of each of his "Doctor Who" stories in his autobiography, "Here's One I Wrote Earlier".
