**Brigadier Alistair Gordon Lethbridge-Stewart** was a companion of the Doctor, and one of their longest standing allies. He was also the head of UNIT, which he helped found, from 1969 to 1977. He first met the Doctors second incarnation as a Colonel. They would cross paths again when the Doctor was investigating International Electromatics. After the Doctor was exiled to earth they crossed paths once again but he was initially unsure if this newly regenerated Doctor was the same man. During the Doctor's exile, the Brig and him became very close, despite disagreements other their methods. Even after his retirement from UNIT, the Brig was often called back into action, frequently alongside successive Doctors.

## Ancestry

Lethbridge-Stewart came from a long line of soldiers, stretching back nearly 400 years, from the Lethbridges in Devon and Stewarts in Lanarck.

## Early life

He was born on the 22nd of February 1930 in Cornwall, England, and was pressured to live up to the military traditions of his family, especially by his father. (LS: *The Forgotten Son*)In 1937, his older brother, James, along with his friends, threatened to make the young Alistair stay in a supposedly haunted house. (THF: *The Bledoe Cadets and the Bald Man of Pengriffen*)

His father was listed as missing in action in 1945, causing him to dislike the military. His mother also insisted that they move town. After the move, the Great Intelligence started removing and changing their memories, removing James, who was now dead, from the memories of both Alistair and his mother. (LS: *The Forgotten Son*)

He liked reading science fiction magazines, but dismissed alien stories as a load of rubbish. (PDA: *Deadly Reunion*)

## Military career

Alistair studied to be a maths teacher, before he was called up for national service in 1950. Whilst serving in the army, he met a Second Lieutenant, who inspired him to enlist in a military school. (*The Ambush!*)

In 1954 he became lost in Sierra Leone, and met a woman called Mariatu. Unknown to him she had a son, Mariama (VNA: *Transit*)

## Meeting the Doctor

Alistair was one of the two survivors of the Yeti attack in Holborn, and was sent to London, where he met the Doctor in their second life. Despite his younger self's disbelief in aliens, he quickly accepted what the Doctor and his companions were telling him about the TARDIS. (DW: *The Web of Fear*)

After this, he pitched an idea for a military intelligence group to specialise in alien invasions, suggesting that the UN might sponsor this. His ideas were denied. (VMA: *Who Killed Kennedy?*)
