On 1 April 1963, Mr Okehurst and several students were killed by the Cold. (PROSE: Time and Relative) In 1963, history teacher Barbara Wright became intrigued by an unusual pupil in the school, Susan Foreman. She and science teacher Ian Chesterton followed Susan home from Coal Hill after Susan gave the address for herself and her grandfather as 76 Totter's Lane, a junkyard. They discovered that their student and her grandfather, in reality the first incarnation of the Doctor, were time travellers from another world. Barbara, Ian, and Susan subsequently left Coal Hill when the Doctor kidnapped the teachers in his TARDIS, which was in the junkyard, to ensure that they couldn't tell anyone about the ship. The Doctor also took his granddaughter away from 20th century Earth against her wishes.
