Ian Chesterton

Ian Chesterton, knighted as Sir Ian, Knight of Jaffa, was one of the earliest companions to travel with the First Doctor. Before meeting the Doctor, Ian was a science teacher at Coal Hill School in 1960s London.

Biography
Ian Chesterton was one of Susan Foreman's teachers at Coal Hill School, London. He was intrigued by her advanced scientific knowledge, and in talking with another of her teachers, Barbara Wright, found that he was not the only person who had noticed the strange knowledge of this pupil. One evening, as school was finishing, Ian and Barbara decided to follow Susan home. They were concerned about her, and curious. When they saw Susan enter I.M. Foreman's junkyard in Totter's Lane, the two school teachers became more concerned for her safety. Following her inside the yard, the two discovered a police box sitting incongruously among the junk. When they discovered that Susan was inside, they barged their way in and Ian discovered something he could not believe. (DW: An Unearthly Child)

Ian's scientific mind made him skeptical of anything he had no proof of. When Susan and the First Doctor told him that the police box was, in fact, a machine which traveled through Time and Space, he was initially doubtful. He felt that the TARDIS was a scientific dream he did not expect to see in a junkyard. However, when the Doctor displayed his disgust at Ian's arrogance and ignorance, Ian stated that he wanted to understand. Once he had proof that the TARDIS was indeed a space-time vessel, he accepted this fact, and became the most practical of the travelers.

It didn't take long for Ian's practical side to show. When the travelers landed in Earth's Stone Age and ran afoul of the tribe they encountered, it was Ian who struggled to free them from their rope bonds, and Ian who 'discovered' fire by rubbing sticks against stone to create friction, in an attempt to win their freedom.

Ian's curiosity about the TARDIS never left him, and he quizzed the Doctor about the TARDIS systems, and how they work, while the travelers were on Skaro. Despite being so obviously interested in science and its practical applications, Ian was not lacking in common sense. While on Skaro he was acutely aware of Barbara's discomfort. He saw how much she wished to return to the safety of the TARDIS, rather than explore the Dalek City, and stood up to the First Doctor in an attempt to ensure their safe return. Once Barbara had been captured by the Daleks, it was Ian who insisted that the travelers could not leave without her.

Headstrong and stubborn, Ian insisted that he should be the one to return to the TARDIS for the anti-radiation drugs the travelers needed, despite the fact that his legs had been paralysed in their encounter with the Daleks, and also despite the fact that the First Doctor and Susan were the only ones who could unlock the TARDIS doors. Eventually it was this stubbornness which prompted Ian to risk his life to warn the Thals about the Dalek ambush, and later persuade them to give up their pacifist ways and fight for their survival. (DW: The Daleks)

Full of bravery and courage, Ian eventually gained the Doctor's respect. He was treated almost as an equal, almost as a friend, and it was no doubt due not only to his bravery, but also to his headstrong, stubborn loyalty. This loyalty extended to Susan and the Doctor as the travelers grew closer throughout their journeys.

Ian reveled in his new life, and new experiences. When the travelers landed in 12th century Palestine during the Crusades, Barbara was abducted in a Saracen ambush. Ian was knighted Sir Ian of Jaffa by Richard the Lionheart, and sent on an emissary mission to search for her. Ian developed his skill as a swordsman during his travels, but he was also capable of unarmed combat. (DW: The Aztecs, The Crusade)

On a number of occasions, Ian endured the severe test of facing his fears. Not being a great swimmer, he found he had to overcome this when, during a visit to Rome in AD 64, he was sold as a galley slave. His galley sank in a storm, and Ian, with his Greek slave friend Delos, escaped and made their way to Rome. (DW: The Romans) While searching for Barbara in Palestine, Ian was captured and staked in the desert, daubed with honey to attract ants. Ian's instinctive fear of ants may have been increased with his experiences on Vortis. (DW: The Web Planet) Ian also appeared to suffer from seasickness when aboard the Mary Celeste, but still managed to make it on deck twice. (DW: The Chase)

Despite his obvious enjoyment of his travels, Ian never lost sight of his desire to return to his home, and his own time. When the opportunity arose, Ian and Barbara risked travel in a Dalek time ship to return to 1960s London. When they emerged from the time machine, they were both delighted to be back home, despite discovering that two years had passed since their departure. (DW: The Chase)

Life after the Doctor
Following his departure from the Doctor, Ian and Barbara got married. However, despite having left the Doctor behind, they had yet again get 'caught up in his world' when they were contacted by UNIT in the 1970s to assist in a temporally related problem (PDA: The Face of the Enemy). Ian and Barbara had a son, John Alydon Ganatus Chesterton (NA: Timewyrm: Revelation, PDA: Byzantium!). According to a rumour Sarah Jane Smith shared with Clyde and Rani, Barbara and Ian had become professors at Cambridge by at least the 2010s and had not aged since the 1960s (SJA: Death of the Doctor).

Personality
Like Barbara, Ian was keen to return home, (DW: The Daleks) prompting him to depart from the Doctor's company at the first possibility (DW: The Chase). He commonly put the interests of others above himself, especially in the case of Barbara whom he always looked after (DW: The Daleks, The Keys of Marinus).

Ian threatened Lobos, saying that killing him might be enjoyable. He may have been bluffing (DW: The Space Museum).

He was acquainted with the music of The Beatles and danced to the track Ticket to Ride (DW: The Chase).

Appearance
Ian continued to wear parts of his Coal Hill School attire whilst travelling (DW: The Daleks). His tie was destroyed when the Doctor tested acidic water with it (DW: The Web Planet). He wore a pinstripe shirt on one occasion (DW: The Chase).

After visiting 13th century China, Ian received a Chinese-style gown (DW: Marco Polo). He continued to wear it on Marinus (DW: The Keys of Marinus).

Behind the scenes

 * The roles of Ian and Barbara as, respectively, science and history teachers was part of the series' original plan to alternate between science-fiction and historical stories. In one of the original format documents, Ian's age is listed as twenty-seven.
 * In the early 1990s, William Russell reprised the role of Ian for a series of links in BBC Video's restoration of DW: The Crusade.
