David Campbell

David Campbell, also called David Cameron, (PROSE: Doctor Who and the Crusaders, A Brief History of Time Lords) was a freedom fighter on Earth during the Daleks' 22nd century invasion and occupation of Earth. He married the Doctor's granddaughter Susan Foreman. According to one account, David biologically fathered Susan's only child, Alex Campbell, and died several years later. (AUDIO: An Earthly Child) By another account, David and Susan instead adopted three orphans — David Junior, Ian and Barbara — and David was eventually killed by while saving the Doctor's life.

Biography
David Campbell was once a Boy Scout, and kept the habit of always carrying a small electric torch in his back pocket ever after. (PROSE: Legacy of the Daleks)

David Campbell met Susan when she and the First Doctor, Ian Chesterton and Barbara Wright landed in a ruined London. By then, he had become a freedom fighter against the Daleks.

They helped him stop the total destruction of the city and helped destroy the Dalek forces. David and Susan quickly fell in love with each other. She stayed with him to help restore the Earth. Shortly after Susan's departure from the TARDIS, they were married. (TV: The Dalek Invasion of Earth)

He helped in the recuperation of the planet, initially by planting crops to feed the survivors. He wondered if he should have agreed to go with the Doctor. Along with Jenny Chaplin, he went searching for Roboman to find a way of recovering. He was tasked with hunting a strange creatures that was found underground which wasn't either a Slyther or a Varga plant. He encouraged Susan to run for leader of the UK to help rebuild it. Marcus Bray wanted his capture as part of his plans against Susan. (AUDIO: After the Daleks)

According to one account, David and Susan had one biological child, Alex Campbell, who was born ten years after they met. David died several years after Alex's birth, and before the Doctor (now in his eighth incarnation) returned to meet Susan and Alex. (AUDIO: An Earthly Child)

According to another account, David and Susan spent at least thirty years together, and were unable to conceive because of the hazards of cross-species reproduction. Still wanting a family, partly because childlessness was stigmatised in the depopulated post-Dalek world, they adopted three orphans, whom they named David Campbell Junior, Ian Campbell and Barbara Campbell, after Susan's husband and former teachers. David was heralded as a great hero for his efforts during the invasion.

By the time that David was fifty-four, he had grown visibly older (and portlier), while Susan still looked eighteen due to her Time Lord physiology. She managed to make herself look older to keep up appearances before their human friends, David and Susan both being rather in view in the elite that arose out of the freedom fighters. However, the discrepancy in their lifespans still put a strain on David and Susan's relationship; although they both still loved each other, Susan found it almost too much to bear to see her beloved decaying before her eyes, and David, for his part, was heartbroken that his being a human put his wife through such hardships. Shortly before his untimely death, David was giving thought to divorcing her for her own good, even if he didn't think he could bring himself to do such a thing.

Eventually, the Doctor (now in his eighth body) returned and met both David and Susan. Soon afterwards, attempted to shoot the Doctor with a pistol, and David threw himself into the line of fire, taking four bullets to the chest and sacrificing his life. The Master did not realise he had murdered one of the Doctor's in-laws, not having recognised Susan. (PROSE: Legacy of the Daleks)

Appearance
The Dalek occupation made David a grim-looking young man. However, he had a friendly and infectious smile that completely transformed his face. (PROSE: Doctor Who and the Dalek Invasion of Earth)
