The very first episode of Doctor Who, titled “An Unearthly Child,” featured the First Doctor (William Hartnell) and his companions – his granddaughter Susan Foreman (Carole Ann Ford) and her teachers, Ian Chesterton (William Russell) and Barbara Wright (Jacqueline Hill) – encountering a tribe from the Stone Age. This initial story showed the show’s original goal: to teach children about history. But just one week later, on December 21, 1963, the second episode transported viewers to an alien planet and introduced the Daleks, completely changing the direction of Doctor Who.
