The First Doctor was played by English actor William Hartnell between 1963 and 1966. Hartnell originally portrayed the character as a very difficult and curmudgeonly person but he matured from an apparent selfishness and became more inviting, learning to be a caregiver with a sense of justice in a universe afflicted by evils.
After fleeing his home world of Gallifrey, the Doctor travels through time and space in his TARDIS. Initially, he travelled only with his granddaughter Susan Foreman. They settled for a time on Earth in 1963, where Susan was a student at Coal Hill School. He was forced to abruptly depart from Earth with Susan’s teachers, Ian Chesterton and Barbara Wright, kidnapping them from their own time after they went to investigate their unusual pupil. After much travel with Ian and Barbara, he bade Susan farewell to allow her to live a happier life with a man with whom she had fallen in love.
Following Susan’s departure, the Doctor travelled for a short time with Ian and Barbara, before landing upon the planet Dido, where he invited a new travelling companion to join him, Vicki. During a confrontation with the Daleks, the Doctor used one of their time machines to return Ian and Barbara to their proper time – something he had been unable to manage with his TARDIS.
Soon after the departure of Ian and Barbara, the Doctor and Vicki had gained a new companion in Steven Taylor, with whom the Doctor had a relatively uneasy relationship. Vicki eventually left the Doctor’s company as well, also after falling in love with a man she met in Ancient Troy. After a lengthy fight with the Daleks, Steven soon became bitter towards the Doctor, blaming him for the several deaths of their travelling companions Katarina and Sara Kingdom, but eventually forgave him. They were then joined by Dodo Chaplet. Ultimately, Steven decided to stay to help a civilisation they had encountered, while Dodo was later injured in an adventure and decided to remain home in her own time, while the Doctor found himself joined by Ben Jackson and Polly Wright, to whom he was much more kind; he hoped to prevent them from leaving as Steven had.
