Ian Chesterton is a fictional character in the British science fiction
television series Doctor Who and a companion of the First Doctor. He
was played in the series by William Russell, and was one of the
members of the programme's first regular cast, appearing in the bulk
of the first two seasons from 1963 to 1965. In a film adaptation of
one of the serials, Dr. Who and the Daleks (1965), he was played by
Roy Castle, but with a very different personality and backstory. Ian
appeared in 16 stories (77 episodes).Ian Chesterton is a science
teacher at the Coal Hill School and works with Barbara Wright, a
history teacher. One of their students, Susan Foreman, the
granddaughter of the Doctor, shows unusually advanced knowledge of
science and history. Attempting to solve the mystery of this
"unearthly child," Ian and Barbara follow Susan back home to a
junkyard, where they hear her voice coming from what appears to be a
police box. When they investigate further, they discover that the
police box exterior hides the much larger interior of a time machine
known as the TARDIS, and are whisked away on an adventure in time and
space with the Doctor and Susan.Ian provides the series with an
action-orientated figure, able to perform the physical tasks that the
elderly Doctor cannot. The Doctor rarely calls him by his first name
(Ian) as the others do but rather as his surname, Chesterton. There
was also a small number of instances where William Hartnell,
mistakingly calls him Chesterfield. His concern, above all, is for the
safety of the TARDIS crew, and in the early stories he often takes
issue with the Doctor's habit of placing the group in harm's way just
to satisfy his own curiosity. The chemistry between Barbara and
himself is also evident, although the nature of their relationship is
never made explicit in the television series, and their eventual
marriage is only revealed forty-five years later.Ian shows a breadth
of skills throughout his tenure with the Doctor. He manages to create
fire (An Unearthly Child), rides a horse, knows how to fight with
swords (The Romans) and is knowledgeable about pressure points that
can paralyse an opponent (The Aztecs). He is also fiercely protective
of Barbara, going on a lone mission to rescue her from Saracens in The
Crusade. In that story, he is also knighted by King Richard I of
England as "Sir Ian of Jaffa". After many travels, Ian and Barbara
eventually use a Dalek time machine to go home, two years after their
disappearance. Ian Chesterton Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
