With William Hartnell stepping down, Innes Lloyd brought in Patrick Troughton. Like his predecessor, Troughton continued to lay down the foundation of the show, and became the Doctor many successors attempt to emulate in some way.

About Patrick Troughton
Troughton was born in 1920, in Middlesex. He attended the Embassy School of Acting and later joined the Tonbridge Repertory Company. One of Troughton’s most famous roles prior to the Second Doctor was in Robin Hood (he was the first the play the title character on television).
Troughton left the show in 1969, citing both a hectic schedule and concerns about being typecast in science fiction. He would return as the Second Doctor for three Multi-Doctor stories before his death in 1986.
