Susan Foreman " Susan " was the assumed name of a Time Lady who was the original companion and granddaughter of the Doctor . As a descendent of Rassilon , Susan travelled with the Doctor during their first incarnation , and reunited with him in their fifth ( TV : " The Five Doctors " ) and eighth incarnations . ( PROSE : " Legacy of the Daleks " ; AUDIO : " An Earthly Child " , et al . ) At different times in her life she was known as " Susan Foreman " , " Susan English " and " Susan Campbell " , but she was usually called simply " Susan " . According to some sources , ( PROSE : " A Brief History of Time Lords " ) her birth name was Larn ( PROSE : " Birth of a Renegade " ) or Arkytior . ( PROSE : " Roses " ) Biography . Early life on Gallifrey . After she left Gallifrey with the Doctor , records of her true identity were deliberately obscured . She was certainly the daughter of the Lord President , ( PROSE : " A Brief History of Time Lords " , " The Magician ' s Apprentice " , " Hell Bent " ) and she was born with a different name than " Susan " , ( PROSE : " Frayed " , AUDIO : " All Hands on Deck " ) which may have been Larn ( PROSE : " Birth of a Renegade " , " A Brief History of Time Lords " ) or Arkytior , from the Gallifreyan for " rose " . ( PROSE : " Roses " , " A Brief History of Time Lords " ) She may have been a direct descendant of Rassilon or of some other founding father of Gallifrey . ( PROSE : " Lungbarrow " , " A Brief History of Time Lords " ) Susan specifically identified the Doctor as her grandfather , ( TV : " An Unearthly Child " , " The Escape " ) as did Barbara Wright , ( TV : " An Unearthly Child " , " Hidden Danger " ) Ian Chesterton , ( TV : " The Ambush " , " Kidnap " ) Ping - Cho ( TV : " The Wall of Lies " ) and the First Doctor himself , ( TV : " The Brink of Disaster " ) while the First Doctor considered Susan to be his grandchild , ( TV : " The Rescue " , " Marco Polo " , " The Sensorites " , " Flashpoint " ) as did the Fifth Doctor , ( AUDIO : " The Toy " ) the Eighth Doctor ( AUDIO : " Relative Dimensions " ) and the First Elder . ( TV : " Hidden Danger " ) In his eleventh incarnation , the Doctor later recalled coming to the Rings of Akhaten " a long time ago with my granddaughter " . ( TV : " The Rings of Akhaten " ) However , other accounts cast doubt on their biological relationship . One , related by , described Susan as Lady Larn , a contemporary of the Doctor whom he had rescued from civil strife on Gallifrey . ( PROSE : " Birth of a Renegade " ) Another intimated that she was one of the last children born on Gallifrey before Pythia ' s Curse , ( PROSE : " Lungbarrow " ) with Patience ' s husband present at her birth . ( PROSE : " Cold Fusion " ) She was sent away from Gallifrey by the Other — her grandfather — to Tersurus during the Great Schism . She later returned to Gallifrey to search for him , where she met the Doctor , whom she recognised as her grandfather reborn . ( PROSE : " Lungbarrow " ) Though she appeared a teenager to human eyes , one account stated Susan was older than Ian and Barbara combined . ( AUDIO : " Here There Be Monsters " ) The First Doctor told Shivani Bajwa Susan was 73 - years - old . ( PROSE : " Doctor Who and the Horror of Coal Hill " ) However , according to the First Doctor , by the time she was on Maitland ' s ship with Ian and Barbara , she was a few years younger than the young human Carol Richmond . ( TV : " Strangers in Space " ) Susan herself told Ping - Cho that she was " in [ her ] sixteenth year " . ( TV : " The Roof of the World " ) Upon seeing a picture of Susan , the hermit said she took after her mother . ( PROSE : " The Three Paths " ) According to " A Brief History of Time " , when the eight - year - old Susan was taken for the selection process in the Drylands to stare into the Untempered Schism , she reacted by running away from what she saw in the Schism . ( PROSE : " A Brief History of Time Lords " ) Susan attended a ritual with the Doctor in Arcadia where gave her a toy . The toy was in reality a communication node in which the Master intended to use to locate the Doctor if he ever left Gallifrey . ( AUDIO : " The Toy " ) Departure from Gallifrey . The First Doctor and Susan left together when they purloined a faulty TARDIS from the repair shop beneath the Capitol . ( TV : " The Name of the Doctor " , AUDIO : " The Beginning " ) The Doctor had brought the flying trunk containing the Hand of Omega with him and Susan had brought basic luggage from her house . Armed guards chased the fugitive Doctor and Susan into the repair shop , where the only place for them to hide was a line of TARDISes . Susan walked into one TARDIS , but the Doctor didn ' t follow her inside . After Susan heard voices outside , the Doctor urged her to go inside the cylinder next to it instead . ( AUDIO : " The Beginning " ) The Doctor was being advised by a version of Clara Oswald to steal the Type 40 with a faulty navigation system instead of the one Susan had walked inside , as it would be much more fun . This account also showed the Doctor already wearing Victorian era dress before he visited Earth . ( TV : " The Name of the Doctor " ) The Doctor speculated that the TARDIS was deregistered , and that was how it slipped through Gallifrey ' s transduction barrier and how they evaded the Time Lords . This account stated the Doctor and Susan already went by these names when they left Gallifrey . ( AUDIO : " The Beginning " ) Their initial trip in the TARDIS was the first time the Doctor had ever piloted a TARDIS . ( PROSE : " The Exiles " , AUDIO : " The Beginning " ) According to one account , the Doctor chose to travel through time , rather than just space . During that first bumpy flight , Susan could not sleep , and began to explore the TARDIS interior . She found a mirror in the wardrobe room that reflected the image of a young man . He stepped out of the mirror , bared a pair of fangs at her , told her she was " not the one " , and disappeared . The Doctor speculated that she had seen an echo through the vortex of something happening in another time . ( PROSE : " The Exiles " ) According to another account , the Doctor and Susan were thrown onto the TARDIS control panel as the TARDIS was seemingly being torn apart . When the Doctor was able to reach for the button marked " flight stabiliser " , Susan collapsed shortly after the engines were stabilised . The Doctor tended to Susan as she slept , and used his jacket as a makeshift pillow for her before she reawakened . Susan then explored the TARDIS as the Doctor tended to the ship ' s controls . She tripped over a rigger ' s work case and brought it back to the Doctor when the TARDIS had run out of power . Inside the work case , the Doctor found an artron cell and attached it to the drive system to power an emergency landing . After finding a nearby world , the TARDIS appeared to take over and brought them to the Moon . ( AUDIO : " The Beginning " ) Long after she had stopped travelling with her grandfather , she described herself as " an accidental passenger " and " a hanger - on " in this first journey from Gallifrey . ( AUDIO : " Here There Be Monsters " ) Meeting humans . According to one account , the Doctor and Susan ' s first destination was a vivarium beneath the surface of the Moon . Before walking outside , they were confronted by Quadrigger Stoyn , who had become an unwitting passenger and had part of his face burned when the TARDIS took off . Stoyn ' s job was to take apart the TARDIS ' engines before it was sent to be vaporised , but the TARDIS had run out of power , stranding them . The Doctor took the dematerialisation circuit so Stoyn wouldn ' t leave them behind and they explored the strange location . The Doctor , Susan and Stoyn were taken out of the tank and realised they were in a massive cavern filled with vivariums carefully - preserved specimens . The Archaeon s had been seeding primitive planets such as the Earth with life by firing red lightning from the Moon , creating an established order out of the chaos and nurturing the early lifeforms under controlled conditions . While checking to see if the TARDIS was a threat , the Archaeons began taking it apart . They took the TARDIS ' temporal stasis capacitor while it was still attached to the power source . This caused the stasis field to breach , freezing the Doctor , Susan , Stoyn and the Archaeons in time , allowing the TARDIS to recharge itself . 450 million years later , human s had evolved on the Earth until they established a lunar colony , Giant Leap Base . A group of humans from Giant Leap Base broke the stasis field , taking the Doctor and Susan on board their lunar rover , where they came to . According to one account , the Doctor and Susan learnt about the Earth ' s history through a " first contact induction video " Susan had been provided while on board the rover . With the dematerialisation circuit still in the Doctor ' s possession , the Archaeons had sent nematode s , which didn ' t affect the Time Lords , to kill all of the humans on the rover . When the Archaeons , found the life they had " seeded " had become disorderly and " run rampant " , no longer matching their carefully - planned vision , they " purged " the humans on the lunar base and on the Earth with lightning . The Doctor , who was blamed for the disruption of the Archaeons ' experiments , was brought back to the cavern . Meanwhile , the humans retaliated against the Archaeons with missile s . After the Doctor went inside the TARDIS , evading the distracted Archaeons , Stoyn tried taking Susan with him , but she refused and ran inside the TARDIS . With the dematerialisation circuit in place , the Doctor and Susan left without Stoyn , as the Doctor felt that he was just as willing to abandon them . Another barrage of missiles breached the atmosphere of the Archaeons ' cavern , destroying their weaponry ; the Archaeons were pulled outside , though Susan saw Stoyn struggle to reach the rover . Afterwards , the Doctor continuously watched the video about the Earth ' s history and evolution inside the TARDIS , marvelling at the planet ' s abundance . He promised it would be his next destination . Instead , his next stop was a place with a blue sun and air like wine . It took several trips before he reached the Earth again . ( AUDIO : " The Beginning " ) According to another account , the first time " Susan " and her grandfather met humans was on the planet Iwa . They were separated . In his search for Susan , the Doctor found a human medical colony . The principal work of the facility , called " the Refuge " , was to rehabilitate patients identified as " Future Deviant s " . By undergoing dream therapy , it was hoped that such individuals would not become criminals . The Doctor soon learned the residents were besieged by fox - like aliens who could disintegrate and reconstitute their bodies . Taking him inside their compound , the humans stripped him of his clothes and burned them , citing possible contamination by the " foxes " . They gave him new clothes drawn from their own supply . This meant that he was now wearing the garb of a doctor . When they assumed that he was sent by Earth to help them , he agreed . Not wishing to give them his real name , he referenced his new clothes to derive a title : " the Doctor " . He agreed to help them with their " fox problem " if they would help him find his granddaughter . They discovered " Susan " had become trapped in the colonists ' " dream chambers " , medical devices that put patients into deep sleep and linked them in one communal dream . Inside the dream chamber , the Doctor ' s granddaughter met a human colonist named Jill , who promptly gave the young girl the name " Susan " , after Jill ' s own mother . Eventually the newly named Doctor and Susan were reunited . They helped the colonists broker an uneasy peace with the foxes . They left the colony , deciding to retain the names they had gained there . The Doctor was deeply impressed by humans during this initial encounter . He told Susan they should find a way to settle amongst them for a while , so that he could study them and they could maintain a low profile on the run from the Time Lord s . ( PROSE : " Frayed " ) The Doctor and Susan travelled to Quinnis where she was interested in a local type of fish . She met Meedla who told her why Bridgetown was on stilts , due to the dangerous ground . When the Doctor was asked to make rain , she spent most of the time running backwards and forwards to the TARDIS . She found out that Meedla was a bird of omen who delighted in the misfortune of the town . After they found the TARDIS after it had been swept away in a flood the Doctor gave her the Blitzen fish that she was interested in . ( AUDIO : " Quinnis " ) At one point Susan had to adventure out of the TARDIS to find medical help for the Doctor when he became ill . When she landed on Rua she discovered that she couldn ' t find any anti - biotics because they had superseded such medicines using nano - technology . She was later chased by a robot , but was in fact a police man Kendrick . Because of her expertise in nanotechnology she helped Kendrick to stop the Butcher but she became upset when Kendrick killed the Butcher . ( AUDIO : " The Sleeping Blood " ) Giving humans a try . Some time after this first meeting with human s , but before taking up residence at 76 Totter ' s Lane , Susan and the Doctor began to study Earth and humans more closely . The precise order of these events was unclear . Some time after their first meeting with humans , the Doctor and Susan began to study Earth and humans more closely , with the French Revolution in France being their first visit to Earth . ( PROSE : " Just War " ) One of their first trips to Earth was to the British coastal town of Keelmouth in 1933 . There , they vacationed at a bed and breakfast called " Bide - a - Wee " . Another of its guests was a time traveller named Prentice . He had used his technology to displace Keelmouth in time ; the village was in 1933 , but the surrounding world was in 1999 . The Doctor and Susan had to convince Prentice to reverse the effect , because his retirement fantasy was not fair to the people he had trapped alongside him . ( PROSE : " Bide - a - Wee " ) Susan was saved from drowning in a boating accident by the then - retire d Brigadier near his house . ( PROSE : " The Gift " ) The Doctor and Susan went to ancient Rome , Antioch , and Jerusalem . ( PROSE : " Byzantium ! " ) On 16 August 1979 , the dematerialisation circuit was fried while the TARDIS was orbiting Earth . The TARDIS was taken on board a Slarvian transport , and the duo learned that the snail - like species planned to conquer Earth by hatching their eggs all over the planet . Their plan failed because the Slarvian ship crashed into the English Channel , making the threat localised to England . With the help of the humans Linda Grainger and her grandfather Edward , Susan and the Doctor stopped the Slarvian eggs from hatching . ( PROSE : " Childhood Living ) " At an unknown point before her schooldays , the Doctor took Susan to see the Rings of Akhaten . ( TV : " The Rings of Akhaten " ) During their travels , she and the Doctor met Noël Coward . ( AUDIO : " The Sleeping City " ) The Doctor and Susan visited London during the Blitz in 1941 . ( AUDIO : " The Alchemists " ) They visited Rome during the time of Augustus . ( AUDIO : " The Alchemists " ) They observed a Zeppelin attack during World War I . ( TV : " Planet of Giants " ; AUDIO : " The Alchemists " ) Shortly before they settled on Totter ' s Lane , they unwittingly travelled to Paris in the 22nd century . They became embroiled in political intrigue in the run - up to an election in the city of Urrozdinee . Departing after the incumbent had been killed , they never quite understood that the city they had visited was what had once been known as . ( PROSE : " Urrozdinee ) " The Doctor and Susan visited Peking during the Boxer Rebellion and used smoke bombs to escape . ( AUDIO : " The Flames of Cadiz " ) The Doctor and Susan visited Dido . ( TV : " The Rescue " ) The Doctor and Susan sailed around the Caribbean on board a pirate galleon . ( PROSE : " Byzantium ! " ) The Doctor and Susan witnessed the assassination of U . S . President William McKinley and travelled to Cassuragi . ( PROSE : " Byzantium ! " ) The Doctor and Susan travelled to Berlin in January 1933 where they went to see Fitz Haber in a scientific institute . Susan found Berlin confusing . The Doctor visited the scientist she met Pollitt in a local cafe , but was drugged by him . After the Doctor was kidnapped , Susan enlisted the help of the SA to locate them . She was later interrogated by Pollitt thinking the Doctor was involved in extracting into gold and wanted to know the secret . ( AUDIO : " The Alchemists " ) On one occasion , they went to central Europe in the 16th century . On the way out of the TARDIS , Susan noticed what looked like a meteorite . She tossed it out , thinking it unimportant , but soon came to realise that it was in fact a part of a Liciax ship . When she tried to find what she had carelessly discarded , it was gone . With the help of a man named Lovey , they traced it to Prague , where they found it had been shaped into a golem . It was definitively alive . It was also on a murderous rampage . The Doctor and Susan trapped it in the attic of a Jewish synagogue , placing it under a security system , to which only they knew the access codes . Some 450 years later , the Fourth Doctor and Romana I returned to retrieve the golem , hoping to take it back to the Liciax homeworld . ( PROSE : " Life from Lifelessness " ) At another time , they accidentally landed at the BBC ' s Paris studios in 1955 because transmissions there had disabled their dematerialisation circuit . They met a radio comedian named Max Wheeler , the star of a programme called " Anyway , As I Say " . His recordings were plagued by a distinctive background " hum " caused by ghostly aliens known as the Shakers . These aliens could kill people with sonic resonance — the thing manifesting itself as a " hum " on BBC broadcasts . During World War II , the British saw the Shakers as a useful ally . They recruited the Shakers into the French resistance . In 1955 , the Shakers were unaware that the war had ended and were unable to clearly understand who their enemies were . Unfortunately , the audiences laughter during the performance of " Anyway As I Say " was , because of its precise harmonics , resonating them out of their " homes " in the walls of Broadcasting House , reawakening them to their murderous task . The Doctor and Susan used canned laugh tracks to force the Shakers out of the walls . Though she and her grandfather tried to explain the current reality to them , the Shakers continued to kill indiscriminately . The only course of action was for Susan and the Doctor to alter the harmonics of the canned laughter and kill them with it . ( PROSE : " Losing the Audience " ) The Doctor and Susan made a short trip to the planet Tacunda . There , they uncovered a jewel called a " Blessing Star " . This crystal altered the laws of probability around the holder , essentially making their dreams come true . The Doctor tried the device , wishing that he could pilot the TARDIS to 20th century Earth . He was successful , it completely fried the navigational system , stranding the Doctor and Susan in I . M . Foreman ' s junk yard in Totter ' s Lane , London . ( PROSE : " The Rag & Bone Man ' s Story " ) Susan and her grandfather took up residence in London so the Doctor could effect repairs . ( PROSE : " Time and Relative " ) One account placed the Doctor and Susan ' s arrival in London before March 1963 . ( PROSE : " Time and Relative " ) Another had Susan say they came here in June , four months before October . ( AUDIO : " Hunters of Earth " ) Before starting school . Susan had a number of adventures before she formally started classes . The Doctor and Susan got lost at night in the dense fog . They met a girl named Joan Calder who sheltered them at her home , where they met her mother and grandfather . During the visit the house burst into flames . On the Doctor ' s instruction , Susan broke a mirror in the house . The elder Calder crumbled into ash and the fire abated . Although the Doctor never was able to adequately explain the event , it was related to the fact that the house had in fact been levelled during the London Blitz two decades earlier . The Doctor postulated that Susan ' s action likely saved the lives of Joan and her mother . ( PROSE : " Ash " ) Life as a schoolgirl . Susan was enrolled at Coal Hill School ( TV : " An Unearthly Child " ) in Shoreditch . ( TV : " The Day of the Doctor " , AUDIO : " Hunters of Earth " ) One account had her enrol there in March 1963 , ( PROSE : " Time and Relative " ) while according to another account , Susan said she had been at Coal Hill since the start of the autumn term . ( AUDIO : " Hunters of Earth " ) Susan took the last name " Foreman " from I . M . Foreman , the name on the gates of the junkyard where the Doctor had hidden his TARDIS . She eagerly sampled the cultural fads of British teenagers . She came to love pop groups such as John Smith and the Common Men . ( TV : " An Unearthly Child " ) She had a John Smith and the Common Men album aboard the TARDIS . ( AUDIO : " " ) She was also interested in beat poetry . This interest led to two adventures with her grandfather , only one of which she remembered . After witnessing a man explode into a protoplasmic mass at a beat poetry reading , she and her grandfather traced the unusual death to a British government project , Operation Proteus . They discovered the project was being run by an alien named Raldonn , who was mutating human s to turn one into his own species so that he would have a co - pilot to help him fly his ship back home . Unfortunately , his efforts relied on a lethal virus that threatened all London . After reversing the effects of the virus , the Doctor and Susan returned to the TARDIS in Totter ' s Lane , whereupon she was taken and then returned to his side without their knowledge . ( COMIC : " Operation Proteus " ) Susan was taken from her time stream to the year 2082 by the Threshold . They had been hunting time travelling humans to send to their clients , the Lobri , who fed on humanity ' s base emotions until they could break free of their psychic plane of existence . Because time travellers could survive the journey to the Lobri ' s " realm " , the Threshold had been particularly interested in the Doctor ' s former companion s , like Peri , Sarah Jane , and Ace . Unfortunately , the Threshold didn ' t realise until after they had captured her that Susan wasn ' t human . The seventh incarnation of her grandfather had to rescue all his companions from the Threshold ' s sinister scheme . He was only successful in this effort because Ace sacrificed herself by blowing up the Lobri and herself with Nitro - 9 . Grieving the loss of Ace , the Doctor wiped his remaining companions ' minds of the event and returned them to their proper times . Susan was returned to the side of her grandfather as they walked back to Totter ' s Lane after the incident . ( COMIC : " Ground Zero " ) At Rosa ' s that October , Susan and sixth form student Cedric Chivers heard a DJ on the radio read a message to them from a future incarnation of the Doctor saying " it ' s blowing in the wind , " and " it ' s all in the beat " . The following day , a mob of Coal Hill students and bikers attacked and chased Susan . The following day , while crossing Mayfield Terrace , Cedric was influenced by a German weapon that had been buried in the terrace during World War II that used radio waves to make young people hate and attack anyone who was different to them . He joined a mob led by Mavis , but stopped when Susan dropped her transistor radio . On Monday , Susan bought Cedric a Bob Dylan LP because of the man on the radio . They were chased by street gangs who chanted " aliens out " , and Cedric brought Susan to his uncle Colonel Rook ' s warehouse , where Cedric revealed he was spying on her , and told her that the Doctor and Susan could be used to fight a war . The Doctor deduced the workings of the weapon , and devised a means of using Susan ' s radio and other pieces in the warehouse to transmit a blocking signal that negated the effect of the weapon . To buy the Doctor more time , Susan used her psychic powers to slow down the oncoming mob . After his life was saved , Rook decided against coercing the Doctor and Susan to fight in the war , and told them that their " secret " would be safe . Afterwards , Susan received a premonition of something coming for the Doctor in his future that he couldn ' t escape . ( AUDIO : " Hunters of Earth " ) Susan continued her life as an ordinary teenage girl at Coal Hill School . She tried , albeit unsuccessfully , to fit in with her classmates . ( PROSE : " Time and Relative " ) This was especially difficult during lessons . There was an obvious imbalance in her knowledge compared with her classmates . She understood advanced physics and chemistry beyond the abilities of her teachers , yet did not know how many shillings made a pound ; she thought the United Kingdom was on the decimal system , which only the United States had in 1963 and hadn ' t yet been introduced to the UK . Her teacher Ian claimed Susan would gradually tell of her knowledge to ensure she didn ' t embarrass her teachers . ( TV : " An Unearthly Child " ) During this time , she used the Blessing Star , hoping it would help her fit in . Instead , it made her extraordinarily lucky , which only further emphasised the differences between her and her fellows . In a fit of pique , she buried the Blessing Star in I . M . Foreman ' s junkyard — an act that would inadvertently help England win the 1966 World Cup . ( PROSE : " The Rag & Bone Man ' s Story " ) Travels with Ian and Barbara . Susan ' s individuality may have been more a problem for her teachers than for her . Susan called her five months on Earth " the happiest of [ her ] life " . When Ian and Barbara followed her home one night to find out more of her mysterious home life , they found the TARDIS . The Doctor kidnapped Ian and Barbara and took a reluctant Susan too , travelling to Earth in the Stone Age . The Doctor was taken by Kal , who had seen him produce fire . The others tried to rescue the Doctor , but were taken to the Cave of Skulls . The Old Mother released the Doctor and his companions and they escaped into a nearby forest . Za was injured by an animal when he tried to chase after them . Ian and Barbara took care of Za , but the group were still sent back to the cave . Ian produced fire for the tribe and devised a way of scaring the cavemen by setting the skulls on fire . The group escaped to the TARDIS , which took off again . ( TV : " An Unearthly Child " ) When the TARDIS landed on Skaro , the Doctor lied about the fluid link needing more mercury , when there was nothing wrong , so he could explore a nearby city . The Dalek s imprisoned the Doctor and his companions inside the city , confiscating the fluid link they brought along . Susan helped the Daleks write an agreement for the Thal s , but once they arrived , the Daleks ambushed them , killing the Thal leader , Temmosus . Having escaped , they assisted the Thals in their attack on the Dalek city . The Daleks ' power supply was damaged in the attack . The Daleks died and their plans to flood the atmosphere with radiation failed . ( TV : " The Daleks " ) With the fluid link retrieved , the Doctor left Skaro for Earth , using the fast return switch . The spring in the switch was damaged , causing it to be stuck . The TARDIS was sent to the beginning of a solar system and everyone was knocked out in the trip . The TARDIS tried warning the crew about the atom s forming around them when they came to , but the Doctor assumed that this was Ian and Barbara ' s sabotage of the ship . Susan had been affected the worst by what had happened . Once Barbara figured out what was going on , the Doctor fixed the spring , ending the fault . ( TV : " The Rescue " , " The Edge of Destruction " ) Still heavily damaged and malfunctioning , the TARDIS found its way to Earth , but did not make it to Ian and Barbara ' s time , instead landing in the Plain of Pamir in 1289 . There , the Doctor and his companions met Marco Polo . Polo took the TARDIS and its keys on his caravan the breadth of Cathay to hand to Kublai Khan as part of a bargain for his return to Venice . During this time , Susan formed a strong friendship with a young girl named Ping - Cho . Along the way , the Mongol warlord Tegana , also part of Polo ' s caravan , tried to take the TARDIS for Nogai as part of his plan to assassinate Kublai . In the chaos of Tegana and Polo ' s duel in Peking , the Doctor and his companions escaped in his repaired TARDIS . ( TV : " Marco Polo " ) The Doctor landed on an island on Marinus . Arbitan asked them to search for the keys to the reprogrammed Conscience of Marinus to regain control over the Voord , as all of his other followers and family members failed to retrieve them . Arbitan trapped the TARDIS in a forcefield , preventing the Doctor and his companions ' escape . They used Arbitan ' s travel dial s to reach Morphoton . Barbara released Arbitan ' s daughter , Sabetha , and the rest of the city from the Morpho ' s mind control , and retrieved the first key . While Ian and Barbara searched for the second key , Susan and Sabetha were trapped inside a mountain cave . Ian , Barbara and Altos rescued them and found the third key deep inside the caverns guarded by Ice Soldier s . In Millennius , Ian was framed for murder . The Doctor stood as defence at Ian ' s trial , but he was sentenced to death . While Susan was held hostage by Kala , the Doctor learnt from her that one of the conspirators in the murder , the prosector Eyesen , was ready to collect one of the keys . Ian was spared execution . The guards captured Eyesen and the last key was found in the mace that killed Eprin . The Doctor and his companions returned to Arbitan ' s island , where Arbitan had been murdered . Ian handed the Voord a fake key , which destroyed the Conscience , along with the Voord . They were able to leave in the TARDIS once more . ( TV : " The Keys of Marinus " ) The Doctor and his companions arrived in an Aztec temple in Mexico . They went through a one - way passage that prevented access to the TARDIS . Barbara posed as the Aztec god , Yetaxa , with the others as her servants , to find a way back . For interrupting the first victim ' s human sacrifice , Susan was sent to a seminary . Susan was to be punished for denying marriage to the Perfect Victim of the Aztecs ' sacrifice and Ian to be executed when he was framed by the High Priest of Sacrifice , Tlotoxl , for attacking the High Priest of Knowledge , Autloc . Autloc ' s faith in Yetaxa was shattered , and he left for the wilderness . The Doctor , Ian and the Doctor ' s accidental fiancée , Cameca , distracted Ian and Susan ' s guard to escape . They worked on a pulley system to open the doorway back to the TARDIS . As they departed , the sacrifice of the Perfect Victim continued as planned . ( TV : " The Aztecs " ) The Doctor landed inside a spaceship in the 28th century , where two crewmembers were suspended in a state resembling death and another , John , had had his mind opened and turned insane , following an attack on their minds by the Sensorite s . The Sense Sphere , which the ship had been trapped around , had its aqueducts ' water supply poison ed with atropine by survivors of a previous human expedition whose ship had been destroyed . The TARDIS ' lock was taken by the Sensorites , leaving the Doctor and his companions trapped on the spaceship . After the Doctor and his companions resisted the Sensorites , the Doctor , Ian and Susan agreed to go down to the Sense Sphere , where the Doctor worked out the cure for this " disease " , which had also afflicted Ian , while the Sensorite scientists treated John . When the Doctor and Ian had gone to the aqueduct to investigate with broken weapons , Susan held a telepathic link with Barbara to help her way through the aqueduct . The Doctor , Ian and Barbara found the human expedition and pretended to be a welcoming party for them and that the " war " against the Sensorites was won . The expedition were taken into custody on Maitland ' s ship . Maitland ' s ship was free to leave and the TARDIS crew had regained their lock . ( TV : " The Sensorites " ) When the Doctor thought he had landed the TARDIS on 1960s Earth , Susan was sceptical as Barbara , Ian and herself found 18th century furniture in a nearby building . In fact they had landed in revolutionary France . She noted that this was one of he grandfather ' s favourite eras of history . Whilst there she was suspected of being a traitor to the revolution and was sentenced to death . On the way to their execution , Susan and Barbara were rescued . However , in the protection of her rescuers she became ill , and learned how primitive medicine was in revolutionary France . The Physician that treated her reported her as an escaped prisoner . Back at the prison , and the Doctor facilitated her second escape , by impersonating an official . ( TV : " The Reign of Terror " ) At some point during her travels with the Doctor , Ian and Barbara , they visited Bob Dovie at 59A Barnsfield Crescent in Totton , Hampshire on 23 November 1963 . ( AUDIO : " The Light at the End " ) When she found out that they had landed Library of Alexandria she looked it up in the TARDIS Library and discovered it ' s fate . ( AUDIO : " The Library of Alexandria " ) When in Seville she helped the Doctor impersonate a cardinal to help Ian get out of prison before he was sentenced to death . With Barbara she rescued him from the flames . ( AUDIO : " The Flames of Cadiz " ) They later landed in a flotila of ships on the planet Hydra where they were captured by Amyra Kaan and Pan Vexel for being stowaways . She was interested in the plight of the Hydran ' s when she heard how they were invaded by the Voord . When the Fortitude sank she spent the following weeks grieving for her Grandfather and Barbara ' s deaths , as well as talking to the captured Voord Nebrin . When Ian and Susan found the TARDIS , Ian forced her to pilot it to take it away from the Voord . Tarlak wished to know how she knew of Yartek and the Marinus mission . When Tarlek found out that the Doctor wished to stop his invasion , he commanded for Susan to be converted into a Voord to stop the Doctor in his plans . ( AUDIO : " Domain of the Voord " ) When the TARDIS landed on the doomed planet Sarath , Susan was taken to hospital after she was injured in a building collapse . When she entered a healing coma , Susan was replaced by an android duplicate as part of a plan by the city ' s supervising A . I . , Monitor , to ensure his own survival , but the original Susan recovered in time to escape incineration . After the truth about the android and Monitor ' s plan was revealed , the android ' s connection to Susan allowed her to resist and disrupt Monitor ' s control , allowing him to be destroyed . With the last few survivors of the planet needing a controlling computer to take the last ship to Mirath , the android volunteered to take on the role , despite knowing that the society on Mirath would be unable to sustain her ( PROSE : " City at World ' s End " ) . In a London devastated by the 22nd century Dalek invasion , Susan fell in love with the freedom fighter named David Campbell ( TV : " The Dalek Invasion of Earth " ) or Cameron ( PROSE : " A Brief History of Time Lords " ) The Doctor realised Susan would never leave him of her own free will ; she thought him dependent on her . Rather than let her choose to stay with him or with David , he forced her hand and locked her out of the TARDIS , bidding her farewell and saying that one day he would return . Meanwhile , she had a place where she could belong , and a home which she confided to David she had never really had . ( TV : " The Dalek Invasion of Earth " ) Ian came to believe that locking Susan out of the TARDIS was the bravest thing that he ever saw the Doctor do . ( AUDIO : " The Revenants " ) Adult life . Susan married and had a family with David . She actively participated in the rebuilding of Earth after the Dalek invasion . ( PROSE : " Legacy of the Daleks " , AUDIO : " An Earthly Child " ) About twenty years after being left on Earth , Borusa captured Susan with a Time Scoop and placed her with the Doctor in the Death Zone on Gallifrey . She met her grandfather in his fifth incarnation ( and , briefly , his second and third incarnations ) , along with Tegan Jovanka and Vislor Turlough , and briefly met Sarah Jane Smith and the Brigadier . She accompanied the First Doctor back to their time streams . ( TV : " The Five Doctors " ) One account suggested that she never told her husband that she was not human . ( AUDIO : " Here There Be Monsters " ) However , others contradicted this . ( PROSE : " Legacy of the Daleks " , AUDIO : " An Earthly Child " ) Susan and David adopted three war orphans and named them Ian , Barbara and David Campbell Junior ; Susan was not able to conceive with David . She worked as a peace officer who made Dalek artefacts safe . The years she spent on Earth caused problems for them . She did not age as fast as humans and was forced to disguise herself to look thirty years older . In 2199 , she encountered whilst investigating a Dalek artefact , and was captured by him to use as a hostage against the Eighth Doctor . Susan was taken in the Master ' s TARDIS to the planet Tersurus , where she revealed that she was also a Time Lord and triggered a psychic scream that forced the Master out of the TARDIS . Believing that she had killed the Master after using his TCE to destroy his equipment and trigger an explosion , she subsequently took his TARDIS . ( PROSE : " Legacy of the Daleks " ) A conflicting account held that Susan " was " able to have a child with David . Her son , Alex Campbell , had only one heart . ( AUDIO : " An Earthly Child " ) She sent the Doctor a hypercube after his birth to tell him of what she had achieved with her life . ( PROSE : " Ghost of Christmas Past " ) When Alex was a teenager , Susan asked the Doctor if Alex could be educated on Gallifrey . The Doctor expressed doubts about David ' s acceptance when told that Alex had only one heart . After David ' s death , Susan became one of the leaders of the Earth council to help with the planet ' s recovery . She contacted the Guldreasi , a seemingly peaceful race that wanted to help Earth . About this time she met with her grandfather in his eighth incarnation and helped stop the Guldreasi enslaving the human race . ( AUDIO : " An Earthly Child " ) Six months later , Susan had Christmas dinner with the Eighth Doctor and Lucie Miller in the TARDIS . She was unhappy when the TARDIS suddenly dematerialised and to find the Doctor was planning on having Alex travel with him . The Doctor was able to return them to the right place and Alex then departed on a tour with Lucie . ( AUDIO : " Relative Dimensions " ) During the tour a plague spread over the Earth , infecting Lucie , though Susan and Alex ' s Gallifreyan heritage made them resistant . Susan was able to use her influence to get Alex and Lucie from Thailand to England . Soon after this the Second Dalek Invasion of Earth occurred . Lucie sent a message to the Doctor when she was infected before the Invasion , but he failed to come till 2 years later . Susan kept her TARDIS Key , thinking she could detect the TARDIS with it . After a failed attack on Dalek operations in North America she realised the TARDIS had arrived . The Doctor was in a Dalek Saucer when it was hit by torpedoes and found unconscious , however Susan realised he could be revived inside the TARDIS , and found her way there . She was able to fly a Dalek Saucer to America with a bomb , Alex and Lucie , hoping to stop the Invasion . However Alex was killed by the Daleks after which Lucie Miller destroyed the Daleks by detonating the bomb , at the cost of her life . Susan and the Doctor were saved by the Meddling Monk , but the Doctor , upset at the deaths , left , leaving Susan to deal with her son ' s death alone . ( AUDIO : " Lucie Miller " / " To the Death " ) After the second Dalek invasion , Susan moved in to Coal Hill School , which had been left abandoned . She had been sent several urgent hypercube s from Gallifrey , asking for her to join the War . The Eighth Doctor tried to remove most of the hypercubes , creating a number of distractions for Susan while he did so . Susan was able to work out his distractions and worked out what was happening . Susan received the message and decided to join the fight , believing that she could help the Time Lords to defeat the Daleks . ( AUDIO : " All Hands on Deck " ) Fate . While the Ninth Doctor twice implied that his " whole family " had died , ( TV : " Father ' s Day " , " The Empty Child " ) the Tenth Doctor once said that he was unsure if she was alive , as he simply had not checked . ( COMIC : " The Forgotten " ) The Eleventh Doctor reaffirmed this , and said that Susan was " lost " , and that he hadn ' t looked for her . ( COMIC : " Dead Man ' s Hand " ) While masquerading as the Doctor ( TV : " Death in Heaven " ) after the revelation of Gallifrey ' s survival at the end of the Time War , ( TV : " The Day of the Doctor " ) Clara Oswald stated that all of his children and grandchildren were assumed dead . ( TV : " Death in Heaven " ) Legacy . The name " Foreman . S . " was recorded on the Roll of Honours Board , which listed both dead and missing staff and students , at the renovated Coal Hill Academy . ( TV : " For Tonight We Might Die " ) The Doctor kept a portrait of Susan in his cottage . ( COMIC : " A Matter of Life and Death " ) The Seventh Doctor told Ace that he thought about Susan everyday . ( AUDIO : " Nightshade " ) The Twelfth Doctor kept a framed photograph of Susan on his desk in his study during the years he spent as a lecturer at St Luke ' s University , along with a picture of his late wife River Song . ( TV : " The Pilot " ) Undated events . At some point , Susan was taken to the Black Archive by UNIT to have her record as a companion of the Doctor taken . Her memories of the visit were subsequently erased and she was sent on her way . ( TV : " The Day of the Doctor " ) The Doctor allowed Susan to borrow the TARDIS for a trip to Venus , but she instead landed on Skaro , where she had an encounter with the Dalek s . ( COMIC : " The Message of Mystery " ) Personality . Susan loved her grandfather , as he did her . She was fond of 20th century England , so she enrolled in school there . Despite the Doctor ' s warnings , she still endangered their secrets . Susan understood contemporary technology and was familiar with historical events , but knew very little about ordinary things , like money . Despite these gaps however , she was still very intelligent , to the extent that teacher Ian suspected she was not only smarter than him , but holding back on her knowledge so that her teachers didn ' t feel stupid . ( TV : " An Unearthly Child " ) Susan considered the Doctor to be a " great man " . ( AUDIO : " Domain of the Voord " ) The Doctor once commented that Susan was " very precious " to him . ( AUDIO : " Masters of Earth " ) Her sheltered life on Gallifrey resulted in her being quick to show fear , either by screaming or calling for her grandfather . She quickly befriended Ian and Barbara but did not accept their claims the Doctor had intentionally damaged his own TARDIS . ( TV : " The Daleks " ) She also seemed to have a sense of humour , having mentioned a liking of memes when visiting the Library of Alexandria ( AUDIO : " The Library of Alexandria " ) , which could take a turn to the morbid side , as seen with her excitement regarding using burning skulls to chase some cavemen off . ( TV : " An Unearthly Child " ) When the fast return switch was stuck , it was Susan who suffered the worst from its effects , possibly due to her having the highest level of psychic sensitivity . She very nearly killed Barbara and Ian . At first she sided with her grandfather , blaming the teachers for the problems . However , she soon recognised their innocence . ( TV : " The Edge of Destruction " ) On Marinus , Susan travelled ahead of the others and was frightened by the jungle and the screams that emanated from it . Despite her earlier truthfulness , the others did not take this seriously . ( TV : " The Keys of Marinus " ) On 22nd century Earth , Susan developed a relationship with David Campbell . The Doctor recognised this and decided it was best to leave her behind so that she could live a normal life . Susan was reluctant , but the Doctor seemed to convince her it was for the best . ( TV : " The Dalek Invasion of Earth " ) She had a son Alex whom she loved dearly . ( AUDIO : " An Earthly Child " et al . ) Behind the scenes . Origins . In reality , this character was originally to have been a princess saved from a planet which wasn ' t the same world as the Doctor came from . Thereafter , she was envisioned as a fugitive from the Doctor ' s home planet . It was Anthony Coburn who altered the character so that Susan became the Doctor ' s granddaughter , instead of being a biologically unrelated female teenager travelling with an old man . ( " The Tribe of Gum ( script ) " , " Doctor Who – The Beginning " ) No televised episode has ever explored Susan ' s origins . The unbroadcast pilot episode features a line of dialogue in which Susan states she is from the 49th century . However , the final televised version , broadcast as the first episode of " An Unearthly Child " , contains no such reference . The contradicting stories regarding Susan ' s origins predate the BBC Wales version of " Doctor Who " . The 2005 version establishes the fact that the Doctor had a family on Gallifrey and intimates , though never explicitly states , that Susan was in all likelihood his biological granddaughter . As of February 2018 , there has never been an indication given in any TV episode to suggest otherwise . Name . Susan ' s name was originally to have been " Suzanne " , while she was being conceived as an alien princess . According to the " Brief Encounter " story " Roses " , Susan ' s real name is ( the Gallifreyan word for ) " Rose " . This allows a subtle connection between the first companion s of the 1963 and 2005 versions of " Doctor Who " . David Whitaker chose to change the character ' s name to Susan " English " for his novelisations , though it ' s unclear why he did so . The later unofficial novel " Campaign " reinstated this use in tribute , but all other novelisations and original novels have used the Susan Foreman name .
