Kate Stewart
Kate Stewart, born Kate Lethbridge-Stewart and nicknamed "Tiger" by her father, was the daughter of Alistair Gordon Lethbridge-Stewart and his first wife Fiona, and was the mother of Gordon Lethbridge-Stewart. Her stepmother was Doris Lethbridge-Stewart. (TV The Power of Three, Battlefield, Enemy of the Bane; PROSE: The Scales of Injustice; HOMEVID: Downtime)
Biography
Childhood
Fiona and Alistair had Kate three years into their marriage, circa 1973. Their marriage lasted eight years. As a child, Kate was never told of her father's work at UNIT with aliens and was only aware that he was a military man. She would often pretend that he was off to have an amazing adventure when she really "knew" he was off to do boring military operations. (HOMEVID: Downtime)
At the time of the Wenley Moor Silurian incident, Kate was five. It was during this mission that Alistair realised that he was an inadequate father for her. The secretive nature of his work with UNIT prevented him from being consistently present in her life. His long absences from home caused Fiona to leave him. Alistair guessed that she and Kate went off to at least initially live somewhere close to Chichester, the home of Kate's maternal grandparents. (PROSE: The Scales of Injustice)
Later life
Eventually Kate grew estranged from her father. (HOMEVID: Downtime)
In September 1990, Kate had a son whom she named Gordon Lethbridge-Stewart, thereby demonstrating a continued love of her father, despite her outward ambivalence and her decision not to reveal her pregnancy or Gordon's existence to him. Gordon's father, Jonathan, wanted to marry her, but she wanted to remain single. Jonathan and Kate split up in 1993, leaving Kate to raise Gordon as a single parent. (PROSE: Downtime) Kate and her son made their home aboard a houseboat moored on an English canal.
Because the cult based at New World University believed she might be able to lead them to the Brigadier, whom they thought possessed a locus vital to the Great Intelligence, she and Gordon were harassed by students who staked out her houseboat. Frightened, she reconnected with her father in 1995 and briefly fought alongside him and Sarah Jane Smith against the New World group. After the Great Intelligence was again defeated, she entered into a friendlier relationship with her dad, and ensured that Alistair could have a relationship with the grandson whom he had not previously known existed.

In 2004, Kate responded to a message from ex-UNIT operative Douglas Cavendish to investigate a haunting. Arriving at Cavendish's isolated cottage, she faced Mastho, one of the last Daemons - a demonic alien race which her father had previously battled more than thirty years before. She and Cavendish saved Earth and its future. (HOMEVID: Dæmos Rising)
Kate dropped the name "Lethbridge" when she joined UNIT so as to be judged on her own merits and not be perceived as being the beneficiary of nepotism. Her father nevertheless quietly mentored her until his death. He instilled in her the position that "science leads", something he learned from "an old friend" (i.e., the Doctor). Kate eventually rose to the post of Head of Scientific Research, and established UNIT as a military organisation led by its scientists. In this capacity, she summoned the Eleventh Doctor and Amy Pond via his psychic paper to the Tower of London to investigate the mystery of the Shakri cubes. Kate attempted to warn the governments of the world of the cubes when they started their countdown. (TV: The Power of Three)
Behind the scenes
- The character of Kate Stewart was created by Marc Platt for the 1995 direct-to-video story, Downtime. Beverley Cressman portrayed the character. A younger version of Kate appeared in the 1996 Virgin Missing Adventures novel The Scales of Injustice by Gary Russell. She would reappear, again played by Cressman in Dæmos Rising. In 2012 she appeared in the television Doctor Who story The Power of Three, almost twenty years after the character was created. Kate's appearance in The Power of Three marked the first time that a character created for an independent spin-off production appeared in the main series, and followed the on-screen début of Prof. Arthur Candy who originated in the spin-off short story, Continuity Errors.
- In The Power of Three, actress Jemma Redgrave, who has naturally brunette hair, appears as a blonde, which matches Beverley Cressman's hair colour in the home videos.
