Alistair Gordon Lethbridge-Stewart
Brigadier Sir Alistair Gordon Lethbridge-Stewart (often refered to as the Brigadier, the Brig, Lethbridge-Stewart or Stewart) was one of the founders of UNIT and commander of its UK operations. The Doctor long considered the Brigadier one of his most trusted human allies and closest friends. He met and had significant adventures with an unusually large number of the Doctor’s incarnations.
Dr. Elizabeth “Liz” Shaw was a civilian member of the United Nations Intelligence Taskforce. An accomplished scientist, Liz assisted the Third Doctor while there. This often involved her winding up in the same life-threatening situations as the Doctor. Generally, Liz was the Third Doctor’s laboratory assistant rather than his travelling companion. She joined him at a time when the Doctor was just beginning his exile on Earth. She expressed disbelief that the TARDIS was capable of flight when she first met the Doctor and remained incredulous for some time thereafter. To the extent that she travelled with him, it was in Bessie or by other, more conventional means.
However, she later travelled in the TARDIS with the Doctor and her successor, Jo Grant, after the Doctor regained his knowledge of time travel. At an unknown time later and for an indefinite period of time, she travelled with the Fourth Doctor, who had deliberately sought her out to apologise for not saying goodbye to her properly.
John Benton was a member of UNIT, serving before, during, and after the Third Doctor’s exile on Earth. He was promoted from Corporal to the rank of Warrant Officer Class 1, holding the post of Regimental Sergeant Major. One source says that he later achieved the rank of Lieutenant. Benton was a corporal when he met the Doctor for the first time, though he was doing surveillance work rather than serving in uniform. He helped the Second Doctor against the Cybermen and Tobias Vaughn.
At some time before the loss of Mars Probe 7, Benton had been promoted to Sergeant, following Sergeant Robin Marshall’s death. This was the rank he held throughout the Third Doctor’s exile and beyond. He quickly formed a close working relationship with the Doctor, Captain Mike Yates and Brigadier Lethbridge-Stewart.
Josephine “Jo” Grant was a civilian employee ofUNIT, whom the Brigadier assigned to the Third Doctor after the departure of Liz Shaw. Initially a laboratory assistant to the Doctor, she became a travelling companion to the Doctor during one-off missions for the Time Lords, and after his exile on Earth was entirely lifted. Although she mostly knew the Doctor in his third life, she also had significant adventures with the Second and Eleventh Doctors, and briefly saw the First Doctor on the TARDIS scanner.
She left UNIT, and therefore the Doctor, to marry ProfessorClifford Jones, who at the time had received United Nations funding for a variety of progressive scientific studies. Their path of their later lives was unclear. Some some accounts saying that they got divorced. Others held that they travelled the world together for years, leaving behind a legacy of environmental progressivism and protests — as well as an abundant number of children and grandchildren.
Captain Michael Alexander Raymond Yates worked alongside Brigadier Lethbridge-Stewart,Sgt. Benton and the Third Doctor in UNIT. Years later, he also had a series of adventures with the Fourth Doctor and Mrs.Wibbsey. According to one account, Yates began as an enlisted man in UNIT. When he first met the Doctor, then in his third incarnation, Yates had just come off of what he called “clean-up duty”. He also came to see UNIT as cash-strapped. The Brigadier took Yates into his confidence and admitted neither the UN nor the UK government would give UNIT enough money for additional officers. He was forced to ask that Yates and Benton shoulder more responsibility than would typically be required of non-commissioned officers. Yates was promoted to a captain at the end of an adventure involving the Glasshouse and the Silurians.
According to another account, Yates was a local military lieutenant temporarily enlisted by Brigadier Lethbridge-Stewart to help him and the Doctor investigate the disappearance of two RAF fighter jets in the area. Subsequently, he was invited into UNIT on a permanent basis and promoted to captain.
Sarah Jane Smith
Sarah Jane Smith was an investigative journalist who travelled with the Doctor in histhird and fourth incarnations. She reunited with him in histenth incarnation and had adventures with him and hisimmediate successor. Sarah Jane met nine of the Doctor’s incarnations in total: those already mentioned and the First,Second, Fifth, Sixth, and Seventh. Due to her experiences with the Doctor, she was entrusted with the task of protecting Earthfrom hostile extraterrestrials and helping peaceful aliens. She shared these adventures with her young companions/surrogate family.
After many trips with her, the Fourth Doctor received a summons to return to Gallifrey, his home world. He told her then that they had to part company because humans weren’t allowed on the planet. Their final words to each other were pleas to not forget them. Standing in the street, watching the TARDIS dematerialise, Sarah realised that, in attempting to take her home, the Doctor had not only missed landing on Hill View Road, but had not landed in South Croydon at all. She remarked to a nearby dog, “He blew it,” before walking off toward her new life. Indeed, the Doctor had mistakenly left her in Aberdeen, Scotland.
