The First Doctor is the original incarnation of the Doctor and the
initial protagonist of the BBC science fiction television series
Doctor Who. He was portrayed by actor William Hartnell.Within the
series' narrative, the Doctor is a centuries-old alien Time Lord from
the planet Gallifrey who travels in time and space in the TARDIS,
frequently with companions. At the end of life, the Doctor
regenerates; as a result, the physical appearance and personality of
the Doctor changes. The concept of regeneration, initially referred to
as a "renewal," was introduced when Hartnell needed to leave the
series, and consequently has extended the life of the show for many
years.Hartnell's portrayal of the character was initially a stubborn
and abrasive old man who was distrustful of humans, but he mellowed
out into a much more friendly, grandfatherly figure who adored his
travels with his companions. The First Doctor's original companions
were his granddaughter Susan (Carole Ann Ford) and her schoolteachers
Ian Chesterton (William Russell) and Barbara Wright (Jacqueline Hill).
In later episodes, he travelled alongside 25th-century orphan Vicki
(Maureen O'Brien), space pilot Steven (Peter Purves), Trojan
handmaiden Katarina (Adrienne Hill), and sixties flower child Dodo
Chaplet (Jackie Lane). His final on-screen companions were the sailor
Ben (Michael Craze) and the posh and sophisticated Polly (Anneke
Wills). Of the 134 episodes Hartnell appeared in as a regular, 44 are
missing. First Doctor Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
