First Doctor

The First Doctor was, by his own statement, the "original" incarnation of the Doctor. (TV: The Five Doctors) Holding himself in high regard, he was prone to criticising those whom he felt were naïve or primitive compared to his intellect. However, he possessed compassion, warmth, and wit that made up for his egocentric nature, serving to act as a mentor and guardian figure in his elderly years. Originally a very difficult and curmudgeonly person, the First Doctor matured from an apparent selfishness and became more inviting. His happier, kinder characteristics fostered when he began to acquire an entourage of companions to accompany him throughout the wonders of the fourth dimension and learned to be a caregiver with a sense of justice in a universe afflicted by evils.

Beginning after he fled his home world of Gallifrey, his travels through time and space were mostly random owing to faulty components in his TARDIS. Initially, he travelled only with his granddaughter Susan Foreman. They settled for a time on Earth in 1963, where Susan was a student at Coal Hill School. He was forced to abruptly depart from Earth with Susan's teachers, Ian Chesterton and Barbara Wright, kidnapping them from their own time after they went to investigate their unusual pupil. After much travel with Ian and Barbara, he bade Susan farewell to allow her to live a happier life with a man with whom she had fallen in love.

Following Susan's departure, the Doctor travelled for a short time with Ian and Barbara, before happening upon the planet Dido, a planet he knew from previous journeys. Here, he invited a new travelling companion to join him, Vicki. She reminded him of Susan, and the Doctor saw her as a surrogate to fill her spot in his travels with Ian and Barbara. Later, during a confrontation with the Daleks, the Doctor used one of their time machines to return Ian and Barbara to their proper time - something he had been unable to manage with his TARDIS.

Soon after the departure of Ian and Barbara, the Doctor and Vicki had gained a new companion in Steven Taylor, with whom the Doctor had a relatively uneasy relationship. Vicki eventually left the Doctor's company as well, also after falling in love with a man she met on one of their travels. Steven soon became bitter towards the Doctor, blaming him for the several deaths of their travelling companions; Katarina and Sara Kingdom, but eventually forgave him. They were then joined by Dodo Chaplet. Ultimately, Steven decided to stay to help a civilisation they had encountered, while Dodo was later injured in an adventure and decided to remain home in her own time.

Shortly before his battle with the Cybermen of Mondas in Antarctica in December 1986, the Doctor had gained two new companions in Ben Jackson and Polly Wright, to whom he was much more kind; he hoped to prevent them from leaving as Steven had. He met his end after battling the Cybermen for the first time. He was forced to regenerate into his second body from exhaustion and a loss of strength to maintain his ancient body after Mondas draiuned a large portion of his life force.

Youth and upbringing
The Doctor was born on Gallifrey, home planet of the Time Lords, "the oldest and most mighty race in the universe." (TV: The War Games, The Time Warrior, The Sound of Drums, Death in Heaven) He was born under the sign of Crossed Computers, the symbol of the maternity service there. (TV: The Creature from the Pit) The infant Doctor slept in his cot under, what Amy Pond later called, a mobile containing "the Doctor's first stars." (TV: A Good Man Goes to War)

One account states that, along with his cousins, the Doctor was loomed into the House of Lungbarrow, and that he was a genetic reincarnation of the Other. (PROSE: Lungbarrow) Many other sources suggested that this was incorrect.

The Doctor stated he had a mother and father, as well as a family and childhood. (TV: The Tomb of the Cybermen, Doctor Who, The Sound of Drums) A later incarnation of the Doctor once claimed that he was half-human on his mother's side. (TV: Doctor Who) He had a brother called Irving Braxiatel. (PROSE: Tears of the Oracle)

During his childhood, the Doctor ostracised himself, going to sleep in a barn where he would weep over his fears, (TV: Listen) and was the "only child left out in the cold". (TV: The Empty Child) When Madame de Pompadour read the Tenth Doctor's mind, she said he was "such a lonely little boy." (TV: The Girl in the Fireplace) He had at least two imaginary friends, named Binker (AUDIO: The Abandoned) and Mandrake. (AUDIO: The Widow's Assassin)

When he was just a "small child," the Doctor's mother told him the story of Grandfather Paradox. The story scared the Doctor so much that he worried that Grandfather Paradox was hiding in his wardrobe or under his bed. (PROSE: The Gallifrey Chronicles)

On "the blackest day of his life," the Doctor claimed that as a little boy, he went to visit a hermit on the side of the mountain his family's house rested on in Southern Gallifrey. While climbing the mountain, the young Doctor saw only dull colored rocks and weeds. However, the Hermit gave no words of advice when he heard the Doctor tell him all his troubles, but instead pointed at a flower, which the Doctor had dismissed as a weed. As he descended the mountain, the world no longer seemed so grim and the Doctor noticed the colors of the rocks and the vibrancy of life in the flowers; his hope restored. (TV: The Time Monster) This hermit would also tell him ghost stories about the King Vampire. (TV: State of Decay)

The Doctor wanted to be an explorer when he was young, but because the Time Lords had already explored every time and place, the Doctor didn't believe there was any point to him becoming an explorer too. He then found a reason and whenever he felt hopeless, he remembered that reason. (PROSE: The Frozen Wastes)

The Doctor once watched a meteor storm on Gallifrey with his father. (TV: Doctor Who) At the age of eight, the Doctor was taken from his family and stared into the Untempered Schism as part of a Time Lord initiation rite. He reacted by running away. (TV: The Sound of Drums)

When he was "little", the Doctor and his childhood friend, the Master, ran together (TV: Death in Heaven) across the fields of the Master's estates by Mount Perdition. (TV: The End of Time) The Master would often hypnotise others, and the Doctor would un-hypnotise them, having learnt hypnotism from the Master. (PROSE: The Dark Path) The Doctor and the Master were bullied as children and the Doctor was forced to kill the bully, Torvic, to save his friend's life. He was later confronted by Death, who insisted he become her disciple. The Doctor refused and asked for Death to take away his guilt, causing her to transfer the memory of committing the crime to the Master instead. (AUDIO: Master)

He was also bullied by Anzor, who used a torture device called "the galvaniser" on his classmates to ensure that they did as he said. He particularly bullied the Doctor, forcing him to do his navigational homework as he was "too stupid to do it himself". He used the galvaniser on the Doctor at least once, as he later threatened to "revive your memory of my galvaniser" to terrify the Sixth Doctor. (AUDIO: Mission to Magnus)

Education
The Doctor left the Gallifreyan equivalent of primary school aged forty-five. (PROSE: Shroud of Sorrow)

The Doctor attended the Time Lord Academy under the tutelage of Borusa and was a member of the Prydonian Chapter. (TV: The Deadly Assassin) He spent "centuries" at the Academy. (COMIC: Mortal Beloved) The Doctor did not have an impressive career at school, passing his qualifying exams to become a Time Lord with only 51% — the lowest possible pass mark — on his second attempt. (TV: The Ribos Operation) However, this was a deliberate ploy to not to draw undue attention to himself, so he could eventually leave Gallifrey. (PROSE: Tears of the Oracle)

During his first year at the Academy, the Doctor gained a troublesome reputation by trapping his teacher in a time-loop for a day (PROSE: Island of Death) and "mucking about" with space-time portals, something the Tenth Doctor indicated were easy to create. (PROSE: Made of Steel)

While he was at the Academy, the Doctor received the nickname "Theta Sigma", or "Thete" for short, from his friends. (TV: The Armageddon Factor, The Happiness Patrol) In the years spent at the Academy, the Doctor belonged to a clique of ten young Time Lords with the collective name of the Deca. (PROSE: Divided Loyalties)

The Doctor rode Vortisaurs bareback at the Academy. (AUDIO: Storm Warning)

Still a "small boy", the Doctor wrote a treatise on the chromosomal origins of love. His tutor said that he missed the point entirely and gave him a "rubbish" grade. (AUDIO: The Wormery) When he was "just a kid" of ninety, he visited the Medusa Cascade. (TV: The Stolen Earth) The Eighth Doctor stated that he was a terror until the age of 120, claiming that he was a late developer. (AUDIO: The Next Life)

He was expelled from the Academy for a time and relegated to traffic control for five centuries after his first encounter with the Celestial Toymaker resulted in the "deaths" of his friends Rallon and Millennia, but he returned to the Academy after receiving his doctorate in his spare time. (PROSE: Divided Loyalties)

In year fifty at the Academy, the Doctor made an enemy of his fellow student, Valyes, after he fed a snapping wart fowl to Valyes' summer project. (AUDIO: The Next Life)

The Doctor didn't attend his time-travel proficiency lesson, which made him unqualified to operate a TARDIS, and rejected an offer to retake the lesson. (PROSE: Festival of Death)

At the Academy, he and the Master joined the Academy's Hot 5 musical band, with the Doctor playing the lead perigosto. (PROSE: Deadly Reunion) He once attended a party on the Moon of Korpal and met fellow academy student, Rummas, but was too drunk to remember. Soon after, he and Rummas began sharing Borusa as a tutor. (PROSE: Spiral Scratch)

On one occasion, he and the Master travelled into Gallifrey's history in search of Valdemar, a dark mass of life created by the Old Ones in the higher dimensions, which swept across creation and wiped out the Old Ones. They met a surviving Old One, who warned them of Valdermar's powers. The Doctor was shaken and was horrified that the Master seemed fascinated by its power. (PROSE: Tomb of Valdemar)

When the Time Lords created the Consolidator to conceal various dangerous historical secrets from the rest of the universe, unwilling to destroy the items or races in the ship in case they proved useful later, the Doctor and the Master were assigned to come up with a solution where their peers failed. The Master had the idea of using a black hole to tear a rift in time and send the Consolidator into the distant future, where the future Time Lords could deal with it, but the Doctor declined to have his name put down on the calculations as he questioned the ethics of the assignment. However, when the experiment was actually attempted, the Consolidator was apparently destroyed by a mistake in the calculations when it struck the edge of the black hole, leaving the Time Lords to hush the matter up (PROSE: Harvest of Time).

The Doctor earned a Higher-Dimensional Physics degree at "Time Lord University." He was required to learn how to envision a superimposed array of 208 different 43-dimensional supersolids, taking eight years to master the skill. (COMIC: The Friendly Place)

Family life
The Doctor was a father at one point in his life, (TV: Fear Her) of both "sons and daughters". (PROSE: The Eleventh Tiger) The Doctor also had three known grandchildren, Susan, (TV: An Unearthly Child) John and Gillian. (COMIC: The Klepton Parasites)

Career
Sometime later in his life, the Doctor was considered a "superior" on Gallifrey. On one instance, he saved a glowing life form from being killed by his old friend Magnus, resulting in a fallout between the two. (COMIC: Flashback)

The Doctor learned of the existence of the miniscopes and was outraged by their cruelty to the specimens within. He campaigned to have them banned and, despite the non-interference policy of the Time Lords, was successful. His role in banning the use of miniscopes was known throughout nine galaxies. (TV: Carnival of Monsters, PROSE: The Empire of Glass)

The Doctor later rescued Patience, the wife of Omega, co-founder of the Time Lord society, along with her granddaughter from danger in Gallifrey's past. (PROSE: Cold Fusion) He possessed a Type 50 TARDIS, which he abandoned when he left and became a renegade. (AUDIO: Prisoners of Fate)

Leaving Gallifrey
One account presented the Doctor existing during a period of civil unrest on Gallifrey, when many students of the Time Lord Academy led by Koschei, revolted against the corrupt Lord President Pundat the Third, and attempted to recruit the Doctor and convince him to take the position as President, but decided not to interfere with the current constitution. When Pundat died of stress soon after the revolt, his chosen successor was Chancellor Slann. The students had found the last of Lord Rassilon’s descendants, Lady Larn, a seven-year old child adopted by Councillor Brolin. They decided on a second coup. Yet in trying to convert the Doctor, the students were overheard.

The Doctor, innocent of the students' revolt, was too highly respected to be terminated like the other students. It was decided to wipe parts of his memory. Bloody reprisals against the students followed, and the Doctor decided to leave Gallifrey in a TARDIS. As it happened, the Lady Larn was hiding in the same TARDIS that the Doctor stole; the Doctor knew her as Susan and she affectionately called him "grandfather". (PROSE: Birth of a Renegade, COMIC: Time & Time Again)

Another account depicted the Doctor living as a lowly Scrutationary Archivist of the Bureau of Possible Events, and disowned by his family in the House of Lungbarrow. In order to replace the disowned Doctor, his family loomed another cousin, Owis. After an encounter with a gloating Glospin, he revealed that there was genetic evidence to suggest that the Doctor didn't originally come from the Lungbarrow Loom, and intended to use it to get the Doctor executed for Loom-jumping. During a fight between the two, the Hand of Omega arrived to attack Glospin, giving the Doctor the opportunity to escape in a Type 40 TARDIS with the Hand of Omega.

The Hand piloted the TARDIS to the Dark Time on Gallifrey to collect Susan, who was the granddaughter of the Other. Susan believed the Doctor was a reincarnation of the Other, and began travelling the universe with him. (PROSE: Lungbarrow, Nightshade) Another account suggests the Doctor broke the Time Lords' law on non-interference and faced being erased from history by his brother Braxiatel. Braxiatel allowed the Doctor to run, giving him the chance to steal a Type 40 TARDIS and escape Gallifrey. He took with him the Hand of Omega and his granddaughter, Susan. (AUDIO: Disassembled)

One account showed the Doctor, already with Susan, ready to steal a faulty TARDIS in a repair shop on Gallifrey. (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. (AUDIO: The Beginning)

He grew a bond with this TARDIS that would last for centuries. When the Doctor first entered the TARDIS, he described it as "the most beautiful thing I ever saw". (TV: The Doctor's Wife)

First flight
One account cited the Doctor and Susan already went by these names when they left Gallifrey. (AUDIO: The Beginning)

According to one account, immediately after leaving Gallifrey, the Doctor rested in the TARDIS console room, while Susan explored their new home. She found a full-length mirror, and saw a pale-skinned fanged figure who vanished after telling her that she was not the one. The Doctor theorised that, since they were now travelling through time, she encountered a brief echo of another era, an event from either the future or the past. (PROSE: The Exiles)

According to another account, 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)

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 Archaeons 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, humans 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 this 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 nematodes, 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 missiles. 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 one account, the Doctor met humans for the first time on the planet Iwa when he and Susan 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 Deviants". 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". The Doctor assumed this alias, because he described it as an honourable profession amongst his own people.

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 Lords. (PROSE: Frayed)

Wanderers in the fourth dimension
Some time after their first meeting with humans, the Doctor and his granddaughter began to study Earth and humans more closely. Revolutionary-era France was the site of the Doctor and Susan's first visit to Earth. (PROSE: Just War) The Doctor and Susan then went to ancient Rome, Mexico, Antioch, Jerusalem (PROSE: Byzantium!) and Akhaten. (TV: The Rings of Akhaten)

On further adventures, they sailed around the Caribbean on-board a pirate galleon, (PROSE: Byzantium!) met Noel Coward. (AUDIO: The Sleeping City) witnessed the assassination of President McKinley, travelled to Cassuragi and visited Mondas and encountered Cybermen for the first time. (PROSE: Byzantium!)

Visiting Earth again in 1979, the dematerialisation circuit was fried while the TARDIS was orbiting Earth. The TARDIS was taken on-board a Slarvian transport, and the two 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 Grainger, the Doctor and Susan stopped the Slarvian eggs from hatching. (PROSE: Childhood Living)

Continuing his TARDIS travels with Susan, the Doctor began pursuing the Soul Pirates, after they had stolen his hand in a sword fight. Whilst following them, they arrived in 1900 London, where Susan and a group of children were kidnapped by the Soul Pirates to harvest their body parts for profit. However, the Doctor foiled this plan, rescued Susan and the children, and received a brand new hand, indistinguishable from the original, from Xing surgeon Aldridge. (PROSE: A Big Hand for the Doctor)

The Doctor and Susan next visited Jabalhabad, India, in 1843, whilst they were touring India by elephant. They met Siger Holmes, father of Sherlock Holmes. (PROSE: All-Consuming Fire) At some point the The Entity took him and tested him to open a door, but the Doctor out smarted him. (AUDIO: Seven to One) The Doctor accepted an invitation to be a guest speaker at a Time Conference on Refkeet Nine and raged against the local authorities when he discovered he had been lured into a trap so that they could use an abused Nuppino horse to attack him. (COMIC: Time Trick)

Soon after, the Doctor and Susan unwittingly travelled to Paris in the 22nd century, where they became embroiled in political intrigue in the run-up to an election in the city of Urrozdinee. (PROSE: Urrozdinee)

The Doctor and Susan went to Berlin in the 1930s. There he met Fitz Haber and planned to help him with his studies. It was when Pollitt drugged Susan when he noticed that something was up and that they should try to leave the place. (AUDIO: The Alchemists)

Arriving at central Europe in the 16th century, Susan noticed what looked like a meteorite and 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, that had developed sentience and 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. (PROSE: Life from Lifelessness)

After landing in Germany in the sixteenth century, the Doctor and Susan teamed up with magistrate Rudolf von Slesinger and an inquisitor, Johann Eck, to protect Martin Luther from two assassins ahead of his trial. Instantly suspicious of Slesinger's odd behavior, the Doctor sent Susan undercover as a servant girl and discovered that Slesinger had deployed the assassins in a plot to kill Luther in secret. Before he could kill anyone, Slesinger was apprehended by Eck. Afterwards, the Doctor and Susan decided to remain in Germany for the trial of Martin Luther. (PROSE: The Price of Conviction)

Vacationing at a bed and breakfast called "Bide-a-Wee" in the British coastal town of Keelmouth in 1933, the Doctor discovered that another guest 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 wasn't fair to the people he had trapped alongside him. (PROSE: Bide-a-Wee)

The Doctor encountered Alistair Gordon Lethbridge-Stewart at Christmas when he and his wife Doris saved Susan from drowning. The Doctor told Doris that he knew how his future friend would die, and that he and his succeeding incarnation have attended his funeral. (PROSE: The Gift)

The Doctor and Susan travelled to Bridgetown on the planet Quinnis in the fourth universe. They nearly lost the TARDIS when it was washed away during a severe flood. They recovered it with the assistance of a huntsman named Evalihi Parch IV, who possessed an ornithopter. (TV: The Edge of Destruction; AUDIO: Quinnis)

The Doctor took a brief trip to St Albans on 17 December 1997 to ensure that the United Kingdom would remain safe during the 1960s, and had a near-miss encounter with the Fourth Doctor, Romana II and K9. (PROSE: The Little Things)

Not long after, the Doctor and Susan 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, whose recordings were plagued by a distinctive background "hum" caused by ghostly aliens known as the Shakers, aliens recruited into the French resistance in World War II, unaware that the war had ended and unable to clearly understand who their enemies were. Though he and Susan tried to explain the current reality to them, the Shakers continued to kill indiscriminately, with the only course of action was for the Doctor to alter the harmonics of canned laughter and kill them with it at a last resort. (PROSE: Losing the Audience)

At this point, the Doctor realised that he and Susan had been losing their memory since they began travelling in the TARDIS due to the telepathic circuits attacking their minds. This prompted their search for somewhere to take residence and recover from the memory loss. (PROSE: Echoes of Future Past) Their loss of memory would stay for sometime after settling in London. (PROSE: Time and Relative)

Hiding on Earth
Making a short trip to the planet Tacunda, the two uncovered a "Blessing Star", a crystal that 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 at piloting the ship, unfortunately, it completely fried the navigational system, stranding the Doctor and Susan in I.M. Foreman's junk yard in Totter's Lane, London in 1963. (PROSE: The Rag and Bone Man's Story)

In late March 1963, the Doctor and Susan took up residence in a Totters Lane junkyard in Shoreditch, London to allow Susan to complete her education, and so the Doctor could effect repairs and build missing components for the TARDIS. (PROSE: Time and Relative) While based in London, the Doctor hid the Hand of Omega, a powerful Time Lord artefact that he had taken from Gallifrey, at an undertakers. (TV: Remembrance of the Daleks; COMIC: Time & Time Again)

Although he was known to be unsociable and unlikely to travel outward, this did not stop his search for knowledge. He at least once visited a library. (TV: The Vampires of Venice)

The Doctor caught River Song sneaking around the junkyard where his TARDIS was located, but he was unaware of her identity. River ran off when she heard Susan. (GAME: The Eternity Clock)

In April 1963, while Susan was attending Coal Hill School, London was consumed by winter weather in the middle of spring, as a result of an extra-dimensional called the Cold awakening. After being coerced by Susan, the Doctor reluctantly decided to interfere in events, and defeated the Cold by depositing it on Pluto in the far future, before it destroyed all humanity on Earth. (PROSE: Time and Relative)

After killing a werewolf with a silver bullet, the Doctor was placed on trial for murder. He was acquitted by the jury which was made up partly of his second, third, fifth and eighth incarnations. (PROSE: The Juror's Story)

After witnessing a man explode into a protoplasmic mass at a beat poetry reading, the Doctor and Susan 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 humans 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. (COMIC: Operation Proteus)

After the Doctor and Susan got lost at night in the dense fog, they met a girl named Joan Calder and sheltered at her home, where they met her mother and grandfather. During the visit, the house burst into flames and, 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 leveled 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)

In October 1963, unbeknownst to Susan, the Doctor started stealing parts to repair the TARDIS. During this period, students of the Coal Hill School and other young people started being taken over by a meteor that crashed in the area. The Doctor and Susan managed to stop this using a transmitter that interfered with the sound waves that caused the meteor to control them. (AUDIO: Hunters of Earth)

The Doctor began investigating an alien insect and planned to take it home. His quick retreat from the 1960s prevented him from doing so. He wouldn't deal with the insect until he was in his fourth incarnation. (PROSE: Those Left Behind)

Meeting Ian and Barbara
Out for a walk, the Doctor's seventh incarnation appeared in his past self's life on a mission from the White Guardian to steal the TARDIS Instruction Manual. Unbeknownst to the First Doctor, the Seventh Doctor saved him from a Dalek and made off with the instruction manual in the confusion. (COMIC: Time & Time Again)

Whilst Susan attended Coal Hill School, two of Susan's teachers, Ian Chesterton and Barbara Wright, followed her home and confronted the Doctor. He launched the TARDIS, kidnapping them so they couldn't tell anyone about them. They travelled to prehistoric times. Kidnapped by a tribesman named Kal, the Doctor was brought to the Tribe of Gum. Susan, Ian and Barbara followed to save him, but Za caught them and placed them all in the Cave of Skulls.

The group was freed by Old Mother, to which the Doctor thanked her, but he grew miserable whilst trekking through the Forest of Fear. When a pursuing Za was wounded by a tiger, the Doctor initially refused to help him. He picked up a rock and was prepared to kill Za, until Ian stopped him, (TV: An Unearthly Child) and a meeting with his eighth incarnation in a time bubble convinced him not too. (PROSE: The Eight Doctors) Recaptured and placed back in the cave, the Doctor tricked Kal into revealing he had killed the Old Mother. The Doctor helped Ian with an escape plan, and the travellers made it back to the TARDIS. (TV: An Unearthly Child)

When the TARDIS landed on Skaro, the Doctor claimed that the fluid link needed more mercury, despite there being nothing wrong, so that he could explore a nearby city. In the city, the Doctor and his friends were captured by the Daleks, confiscating the fluid link they brought along.

Having escaped, they assisted the Dalek's enemy, 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) However, this was not the last the Doctor saw of the Daleks, as he would go on to battle them many times in his future, and they would become his greatest enemy, with the Doctor making it his mission in life to combat threats similar to the Daleks. (TV: The Dalek Invasion of Earth , Dalek, Victory of the Daleks, Into the Dalek)

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 atoms forming around them when they came to, but the Doctor assumed that this was Ian and Barbara sabotaging the ship. Once Barbara figured out what was going on, the Doctor fixed the spring and apologised to his human companions, ending the fault. (TV: The Edge of Destruction) After this incident, the Doctor's relationship with Barbara and Ian became more warm, and he began to learn about and respect their humanity. (COMIC: Hunters of the Burning Stone)

Further adventures
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 to the breadth of Cathay to hand to Kublai Khan as part of a bargain for his return to Venice. 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 the repaired TARDIS. (TV: Marco Polo)

Arriving inside the tomb of Menkaure in Egypt in 26th century BC, the Doctor, Susan, Ian and Barbara were arrested and taken to the palace. Itennu planned to assassinate Pharaoh Menkaure with a poison dart and then blame the strangers. However, the Doctor inadvertently foiled the attempt with his walking stick and, when a more open attack began, the travelers fled back to the TARDIS, once again barely escaping with their lives. (COMIC: The Forgotten)

The Doctor next travelled to London during World War II and discovered the Bansharai, alien shape shifters who survived on emotions, had been posing as dead people to make the wishes of their loved ones come true. (PROSE: Tell Me You Love Me)

The TARDIS landed on an island on Marinus, where Arbitan asked the Doctor and his friends 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. When the Doctor refused his aid, Arbitan trapped the TARDIS in a forcefield, preventing the Doctor and his companions' escape. They used Arbitan's travel dials 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.

The Doctor jumped ahead to Millennius, the location of the final key, to find Eprin. Once Ian had found two more keys, he was knocked out and framed for Eprin's murder. The Doctor stood as defence at Ian's trial, but Ian was sentenced to death. The Doctor learnt that one of the conspirators in the murder, the prosecutor, Eyesen, was ready to collect one of the keys and 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 leader Yartek 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. Barbara tried and failed to change the Aztecs' history of human sacrifice for the better, which the Doctor strongly advised her against.

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 and Ian 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 and his friends next arrived 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 Sensorites. The Sense Sphere, which the ship had been trapped around, had its aqueducts' water supply poisoned 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.

The Doctor and Ian, followed by Barbara, went to the aqueducts where Atropa belladonna had been growing. They 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)

Greatly agitated by Ian and Barbara's remarks, the Doctor landed the TARDIS on board the Endeavour sailing ship in 1770. There, he and Ian met Captain James Cook, but, before Susan and Barbara could exit the ship, it was tossed overboard in a violent storm. Greatly saddened by the loss of the girls, the Doctor and Ian continued on the Endeavour's voyage for several months towards Australia observing the transit of Venus along the way.

Their time on the Endeavour ended when they discovered Susan had managed to swim out and attach a line to the sailing ship from the TARDIS and so be pulled along behind it. The travellers' joy at being reunited was short lived when the Doctor became disgruntled again because the TARDIS floor was now covered in patches of water. (AUDIO: The Transit of Venus)

The TARDIS then landed in France in the middle of their revolution. They were immediately caught in the depth of the war, and Ian, Barbara and Susan were all sentenced to death. The Doctor helped find an English spy named James Stirling who could help them to escape. Escaping their jail cells, they made their way through the French and back to the TARDIS, where they made a narrow escape. (TV: The Reign of Terror)

After escaping from France, the Doctor wanted to relax, but found himself on a planet with a fast time rate, and discovered the entire civilisation of the planet had been based around him, Ian, Barbara and Susan. He and his companions then watched the rise and fall of the civilisation in a matter of minutes. (PROSE: Rise and Fall)

However, the Doctor was able to free her of the infection. (PROSE: Nothing at the End of the Lane)

When the TARDIS was attacked by a bomb bought by, which caused the TARDIS to destroy itself second-by-second, the Doctor, with the help of the Second and Third Doctors, was able to summon his other five successors to stop the bomb from ever going off. He then was able to discover that it was his TARDIS' automatic distress actions that had brought all of the Doctors together and had destroyed their TARDISes. He turned the signal off, and thus the events of that day ceased to be.

The Master's plan foiled, the Doctor visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963, (AUDIO: The Light at the End) and became caught up in an experiment with time travel in a future London. (PROSE: The Time Travellers)

In a further attempt to return Ian and Barbara home, the TARDIS malfunctioned, and they landed in a place filled with giant bugs and long, winding paths. Ian and Susan found a gigantic match box, while the Doctor and Barbara found a worm. Ian was trapped in the match box, which was taken by a man named Farrow. The Doctor deduced that they were on Earth, but they had been shrunk down to the size of an inch.

Farrow met with Forester to tell him that his insecticide had been rejected, and was killed by Forester. The crew, looking for Ian, heard the gunshot and ran to the scene, where they were menaced by a cat. Entering the house, Barbara began to die when she touched the insecticide. She proceeded to contact someone through a telephone and reached Hilda Rowse and her husband Bert. They managed to grow back to size and Barbara recovered. Forester and his accomplice, Smithers, were handed over to the police. (TV: Planet of Giants)

Leaving Susan behind
In London during the time of the 22nd century Dalek invasion, Susan met David Campbell, a young man fighting against the Dalek occupation. Realising she would be better off not facing the dangers of travelling with him, and recognising she was no longer a child, the Doctor reluctantly left her behind, promising to return, (TV: The Dalek Invasion of Earth) though he did not until his eighth incarnation. (PROSE: Legacy of the Daleks)

Although he later reunited with her briefly for an adventure on Gallifrey, (TV: The Five Doctors), he continued to regret this decision for centuries to come (PROSE: Planet of the Bunnoids; COMIC: The Forgotten) and even slept through a materialisation because of his sorrow. (TV: The Rescue) Ian believed that locking Susan out of the TARDIS was the bravest thing that he ever saw the Doctor do. (AUDIO: The Revenants)

Shortly after leaving Susan in the 22nd century, the Doctor travelled to Venus to attend the funeral of Dharkhig, an old friend of his. There, the Doctor, Ian and Barbara became embroiled in the Venusians' conflict with their would-be saviours, the Sou(ou)shi. (PROSE: Venusian Lullaby)

The Doctor almost lost Ian and Barbara as companions when they considered settling down in 1950s Shoreditch, and he spent four months investigating the Stone of Scone in Scotland.

After nine years of war, the Doctor used a book from Gallifrey to repair time, erasing the alternative history and costing Barbara her husband. (PROSE: The Book of Shadows)

The Doctor had a second encounter with River Song during his travels with Ian and Barbara. River Song considered the First Doctor to be boring, because he spent his time hanging out with the two teachers. River wiped his memory with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)

More companions
Arriving on Dido, the Doctor was puzzled by Koqullion, a strange monster who was menacing the two survivors of a crashed spaceship. The Doctor gained a new companion in one of the survivors named Vicki Pallister, who immediately became a surrogate for Susan. He saved her from Koquillion, who turned out to be the other survivor, a murderer named Bennett. (TV: The Rescue)

Immediately following their departure from Dido, the TARDIS landed in 64 AD in the area just beyond the great metropolis Byzantium.

Death
With his ancient body wearing thin, the increasingly frail Doctor matched wits with the Cybermen on Antarctica in December 1986, an encounter which resulted in his life force being drained from him by Mondas.

After defiantly claiming things as "far from being all over", he quickly returned to the TARDIS, without pausing to wait for Ben and Polly, as he sensed his time was coming to an end. Entering the control room, he found the controls operating of their own accord and saw that the central column began to rise and fall. Ben and Polly, having caught up with him, were locked outside the TARDIS and banged on the doors in protest. Managing to open the doors with the last of his strength, the Doctor collapsed, having lost the energy needed to keep his old body going. (TV: The Tenth Planet)

As his twelfth incarnation recalled, his first regeneration was when he realised that "[he] wasn't who [he] thought [he] was". The Doctor's regeneration felt like "the end of everything" as every particle in his body was dying. (COMIC: Blood and Ice) Before the astonished eyes of his companions, the Doctor regenerated for the first time, transforming into a much younger body. (TV: The Tenth Planet)

Undated adventures

 * At some point, before meeting Vicki, the Doctor visited Dido. (TV: The Rescue)
 * The First Doctor visited Mondas. (PROSE: Byzantium!)
 * The First Doctor attended the funeral of Alistair Gordon Lethbridge-Stewart, as did his future incarnations. (PROSE: The Gift)
 * Before he met Ian and Barbara, the Doctor argued with Henry VIII and was sent to the Tower of London, where he could escape in the TARDIS. (TV: The Sensorites)

Alternative timelines

 * In an alternate timeline created by the Black Guardian as revenge on the Doctor, the First Doctor never left Gallifrey, and eventually became Lord President. However, it also left Earth to be invaded by countless aliens, who were then in war over the planet. The Seventh Doctor, Benny, and Ace, with instructions from the White Guardian, were able to retrieve the Key to Time to set the timeline straight. (COMIC: Time & Time Again)

Personality
The First Doctor was an unreadable, guarded figure who was, at first, slow to trust newcomers who learnt of him, but once his trust had been earned, he would show another side of himself as a staunch anti-authoritarian with a mischievous streak. (TV: An Unearthly Child) He was protective of the young women he took on as companions; they reminded him of his granddaughter, Susan.

The Doctor held himself in high regard, and was prone to criticise those whom he felt were naïve or primitive compared to his intellect. (TV: An Unearthly Child, The Reign of Terror) However, he possessed compassion, warmth, and wit that made up for his egocentric nature, serving to act as a mentor and guardian figure in his elderly years. Originally a very difficult and curmudgeonly person, (TV: An Unearthly Child, The Edge of Destruction) the First Doctor matured from an apparent selfishness and became more inviting. (TV: The Rescue, The Time Meddler, The Smugglers) His happier, kinder characteristics fostered when he began to acquire an entourage of companions to accompany him throughout the wonders of the fourth dimension and learned to be a caregiver with a sense of justice in a universe afflicted by evils. (COMIC: Hunters of the Burning Stone)

The First Doctor's strongest trait was his grandfatherly approach to things. He was always looking out for Susan, even lecturing her many times and telling her off. (TV: An Unearthly Child) His last act of paternity towards Susan was to leave her in the 22nd century with David Campbell, a freedom fighter she had fallen in love with, to start her own life. (TV: The Dalek Invasion of Earth) His grandfatherly ways were then passed over to Vicki Pallister, (TV: The Chase) and Polly Wright. (TV: The Tenth Planet)

When the Doctor first met Ian and Barbara, he abducted them and set the TARDIS console to shock Ian into unconsciousness. He justified his actions by claiming he was keeping himself and Susan safe. He regarded humans as primitives and contemplated killing the mortally wounded Za so that he would not slow down the Doctor's party. When Ian caught him apparently ready to bludgeon the man with a rock, the Doctor explained he merely wanted Za to draw him a map, (TV: An Unearthly Child) but this was, in fact, a lie to cover up his murder attempt. (PROSE: The Eight Doctors) When first visiting Skaro, the Doctor was willing to risk everyone's safety so he could satisfy his own curiosity, resulting in them nearly dying from radiation poisoning in the prison cells of the Dalek city. (TV: The Daleks) He also threatened to throw Ian and Barbara into the Time Vortex after accusing them of sabotage. When proven wrong, the Doctor humbly apologised. (TV: The Edge of Destruction)

Despite this, even during his dark beginning, the Doctor showed signs of a kinder persona, being quick to bargain with the Tribe of Gum for Ian's safety. (TV: An Unearthly Child) He also offered the Daleks the TARDIS in return for Susan's safety and took it upon himself to ensure the Thals were not threatened with extinction. (TV: The Daleks) The Twelfth Doctor later opined that his experience on Skaro shaped his identity for the better. (TV: Into the Dalek)

As the Doctor travelled more, he began to thaw and help people, albeit reluctantly at times, such as on Marinus, where he only agreed to help Arbitan restore the Conscience of Marinus after he was blackmailed, (TV: The Keys of Marinus) and more willingly on other occasions, such as when he landed during the 21st century Dalek invasion. (TV: The Dalek Invasion of Earth) Later, the Doctor was quick to help the Rills in their fight against the Drahvins on a doomed planet, noting that bias based on appearance was unwelcome, (TV: Galaxy 4) negotiated the release of the Monk from the Daleks, despite peace not being brokered between the two Time Lords, (TV: The Daleks' Master Plan) and, upon witnessing the persecution of the "savages", was quick to ally himself with them against the Elders, defying their suggestions that progress was based on exploitation, branding it as "protracted murder". (TV: The Savages)

The Doctor came to the defense of established history when Barbara attempted to alter the nature of the Aztec civilisation, claiming that not a single line in history could be altered. (TV: The Aztecs) Nevertheless, he gave first aid to the injured de Tornebu, justified stealing clothes based on the fact they were already stolen - finding his shoplifting of the clothes humorous - and tried to convince King Richard to carry out his peace plan. (TV: The Crusade) However, when he first challenged the Monk, the Doctor quickly labeled him a "time meddler" and quickly continued to uphold his belief that history could not be changed. (TV: The Time Meddler) In Paris 1572, the Doctor again backed up his previous ideal that it was permissible to save people who were not directly contributing to historical events. (TV: The Massacre of St Bartholomew's Eve)

When he disagreed with something, the Doctor would scorn and get angry – denying the facts his companions gave to him in these situations. (TV: The Edge of Destruction, The Chase, The Time Meddler) He was frequently sarcastic towards those around him, seemingly to elevate himself above lesser intellects. (TV: The Time Meddler) He would get particularly snappish with those who doubted the TARDIS could actually travel through space and time. (TV: An Unearthly Child, The Time Meddler)

The Doctor did not associate himself with a specific culture, claiming to be "a citizen of the universe, and a gentleman to boot," (TV: The Daleks' Master Plan) and did not allow others to intimidate him. (TV: The Sensorites, The War Machines) He once stated his belief that there was a reason for everything in the universe and claimed to have "the directional instinct of a homing pigeon". (TV: The Chase)

Several of his future incarnations had a noticeably profound respect for the first incarnation, so much so that they dared not question his judgment, or argue in his presence. (TV: The Three Doctors, The Five Doctors) The Eleventh Doctor was an exception to this, as he looked upon his original incarnation with shame, branding him a "selfish idiot", and a coward. (COMIC: Hunters of the Burning Stone)

While Susan once described her grandfather as being a "great man", the Doctor considered himself to be very dangerous when roused. (AUDIO: Domain of the Voord, The Doctor's Tale) Geoffrey Chaucer, meanwhile, described the Doctor as being "a man of rare wit and temper, a philosopher." (AUDIO: The Doctor's Tale)

After his struggle with the Celestial Toymaker, the Doctor felt increasingly unwell and speculated that his first regeneration was nearing. (PROSE: The Man in the Velvet Mask) Though he was initially afraid of the change, (PROSE: Ten Little Aliens) the Doctor put on a brave face to comfort Polly Wright while dying as a prisoner of the Cybermen. After Ben rescued them, the Doctor returned to the TARDIS, using the last of his strength to unlock the door for Ben and Polly, (TV: The Tenth Planet) and then regenerated while terrified, until he realised that rather than being the "end of everything", it was a "new beginning". (COMIC Blood and Ice)

Habits and quirks
The first incarnation punctuated his speech with exasperated sighs and snorts, the occasional mangled phrase or word, (TV: The Daleks, The Keys of Marinus, The Reign of Terror, The Chase, Galaxy 4, The Myth Makers) and "Hmmmm?". (TV: An Unearthly Child, The Reign of Terror, The Romans, The Chase, The Myth Makers, The Daleks' Master Plan, The Celestial Toymaker) He would address young women as "child" and younger men as "my boy", (TV: The Ark, The Tenth Planet) or in Ian's case by his surname, even though he found it difficult to remember. He also made a habit of repeatedly uttering "dear". (TV: An Unearthly Child, The Rescue)

The Doctor tended to hold onto his lapels while speaking or thinking, (TV: The Edge of Destruction, The Sensorites, The Dalek Invasion of Earth, The Web Planet) and he would often release a little chuckle when something made him laugh. (TV: An Unearthly Child, The Romans, The Time Meddler, The Celestial Toymaker) Whenever he coughed, he would waft his tissue around. (TV: An Unearthly Child)

The Doctor never stated or even hinted at the nature of his own origins, other than to hint that Susan and himself were exiles from another place and time, (TV: An Unearthly Child) and to state that he and the Monk originated on the same world. (TV: The Time Meddler)

The Doctor often made speeches, (TV: An Unearthly Child, The Edge of Destruction, The Dalek Invasion of Earth, The Daleks' Master Plan, The Massacre of St Bartholomew's Eve) and had a knack for metaphors (TV: An Unearthly Child) and proverbs. (TV: The Daleks, The Edge of Destruction, The Keys of Marinus, The Sensorites, The Reign of Terror, The Space Museum)

Skills
The First Doctor was more of an intellectual incarnation, due to his older and frail appearance, and would mostly leave the fighting to Ian, Steven or Ben. He was certainly a thinker when it came to defeating his enemies; strategising the best way of defeating or tricking them. (TV: An Unearthly Child) Because of this, the Elders recognised him as a man of infinite wisdom. (TV: The Savages)

Whilst normally peaceful, the Doctor would, when pressed, resort to hand-to-hand combat with an effectiveness which belied his age. (TV: The Romans, The Crusade, The Chase, The Daleks' Master Plan) At other times, however, the Doctor revealed age-related vulnerabilities, such as the rheumatism he suffered from, that flared up if he was exposed to cold. (TV: The Space Museum)

The Doctor was also a skilled gambler, being able to win half of Asia in game with Kublai Khan. (TV: Marco Polo) Another ability of his was the ability to sense alien presence, getting goosebumps upon seeing the Post Office Tower and claiming that there was "something alien" about it. (TV: The War Machines)

Having been taught by the Master, (PROSE: The Dark Path) the Doctor could perform hypnosis with his signet ring, utilising it to break Dodo Chaplet's mind control by the artificial intelligence WOTAN, causing her to sleep for two days and forget her ordeal. (TV: The War Machines)

Appearance
In his youth, the Doctor had short, dark hair (TV: Listen), and claimed that he was considered "quite a looker". (PROSE: The Plotters)

In his later life, he had shoulder length, greyish-white hair which grew around the back of his head. He had piercing blue eyes. (TV: An Unearthly Child)

Clothing
The Doctor affected a slightly eccentric Edwardian dress sense, wearing a black shawl collar double breasted Town Coat, a yellow tweed waistcoat over a white shirt with a black ribbon tie, yellow-themed tartan trousers, (TV: An Unearthly Child) and shiny elasticated boots. (TV: The Tenth Planet) Occasionally, he would wear a cape, (TV: Planet of Giants, The War Machines) or sport half-moon reading glasses. (TV: The Time Meddler, The Daleks' Master Plan, The War Machines)

He wore a blue signet ring on the middle finger of his right hand, (TV: An Unearthly Child) which had special powers, such as to unlock the door of the TARDIS. (TV: The Daleks' Master Plan) On one occasion, the ring appeared to both facilitate hypnotism and protect the Doctor from electrical shock. (TV: The War Machines) On occasions, he did not wear his ring, and wore fingerless gloves instead. (TV: The Tenth Planet, The Five Doctors)

Occasionally, he would wear an Astrakhan, (TV: An Unearthly Child, The Tenth Planet) or a white. (TV: The Chase, The Daleks' Master Plan) He also used a smoking pipe on at least one occasion, (TV: An Unearthly Child) and also employed a walking stick given to him by Kublai Khan. (TV: Marco Polo)

When adventuring in Earth's past, the First Doctor, in contrast with his successors, sometimes made significant changes to his wardrobe in an attempt to blend in with the local population, (TV: The Reign of Terror, The Romans, The Crusade) and would gladly accept the vestments of extraterrestrial societies, as when he proudly wore the ceremonial garb of the Elders. (TV: The Savages) He usually made at least a token alteration to his standard outfit wherever he went in Earth's past, as when he wore a cowboy hat in 19th century Arizona. (TV: The Gunfighters)

Mysteries and discrepancies
One account explained that the Doctor rescued Larna, a young Time Lady from the Doctor's own time, whom he later called Susan. (PROSE: Birth of a Renegade) Another account stated that the Doctor had gone back in time to the Dark Times of Gallifrey to pick up both the Other's granddaughter and the Hand of Omega from that time period. (PROSE: Lungbarrow) Other accounts describe the Doctor as a father and a grandfather; the Tenth Doctor said that he "was a dad, once". (TV: Fear Her) and that he'd "been a father before". (TV: The Doctor's Daughter) The Twelfth Doctor once said he had "dad skills". (TV: Listen) Clara Oswald stated that the Doctor had "children" and "grandchildren", who were "missing, presumed deceased" by the time of the Last Great Time War and Gallifrey being moved to another dimension. (TV: Death in Heaven)

This incarnation of the Doctor seemed unfamiliar with the Daleks, and demonstrated eagerness to explore their homeworld Skaro. (TV: The Daleks) However, the Eleventh Doctor revealed that as a child, he was fond of a children's story called The Emperor Dalek's New Clothes. (TV: Night Terrors)

Other matters

 * This Doctor was one of only two incarnations ever known to smoke, (TV: An Unearthly Child) the other being the Eighth Doctor, although this only took place when the Doctor's mind and personality were briefly 'mixed up' with traits from his companion Fitz Kreiner. (PROSE: Halflife)
 * When the Doctor, Vicki Pallister, Barbara Wright and Ian Chesterton were being chased by the Daleks through time, he claimed to have built the TARDIS. (TV: The Chase) On the face if it, this statement appears to be in contrast with later incarnations and Time Lord authorities who claimed that the TARDIS was "borrowed"/"stolen", (PROSE: The Gallifrey Chronicles, TV: Planet of the Dead) an account the TARDIS itself agreed with. (TV: The Doctor's Wife) It has also been suggested that the TARDIS was better described as having been "grown", rather than "built". (TV: Rise of the Cybermen, The Impossible Planet)
 * Additionally, Susan had made the claim that she coined the acronym TARDIS, (TV: An Unearthly Child) implying that the Doctor may have been somehow involved with the development of the TARDIS. The eighth incarnation revealed that he had made various additions to the TARDIS to replace the need for a direct symbiotic link to control the TARDIS and thus make it harder for the Time Lords to find him, suggesting that, while the Doctor did not build the TARDIS from the beginning, he made significant alterations to it after it came into his possession. (PROSE: The Taking of Planet 5)
 * The matter of this incarnation's age and how long this incarnation lived was unclear, although Susan once called him an adolescent by Time Lord standards; (AUDIO: Here There Be Monsters) shortly after his regeneration, his next incarnation stated that he was around 450 years old. (TV: The Tomb of the Cybermen)

The Brilliant Book 2011
According to The Brilliant Book 2011, a non-narrative based book, the First Doctor met Winston Churchill in 1911, stepping out of the TARDIS to tell Churchill it was an honour to meet him. When Churchill informed the Doctor they had met before, the Doctor chuckled and said, "That's the trouble with time travel".

Casting
Actors considered for the role of "Doctor Who", as he was then known, included Geoffrey Bayldon , Cyril Cusack, Hugh David and Leslie French. (Bayldon would later play an alternate version of the First Doctor in two Unbound adventures for Big Finish Productions: NOTDWU: Auld Mortality and NOTDWU: A Storm of Angels.) William Hartnell had, up until that point, mainly played small-time thugs and other unsympathetic parts in crime films and humourless military men in comedies. Producer Verity Lambert was inspired to ask him to accept the role after seeing him in his well-known role in, which convinced her that he could play a tough, yet shaded and sympathetic character.

During the First Doctor's tenure, other actors occasionally stood in for Hartnell, either for demanding scenes, or due to Hartnell being ill or otherwise unavailable. Edmund Warwick stood in for Hartnell in one episode of The Dalek Invasion of Earth, and played the real Doctor in some scenes of The Chase when Hartnell was playing the Robot Doctor. In The Tenth Planet, Gordon Craig acted as a body double for Hartnell during the snowstorm scenes in the first episode, and then all of the third episode, after Hartnell was taken ill.

When the time came for the First Doctor to appear in the 1983 Children in Need anniversary special TV: The Five Doctors, actor Richard Hurndall was hired to play the role, standing in for William Hartnell, who had died in the mid-1970s. A clip of Hartnell as the Doctor from The Dalek Invasion of Earth preceded the opening titles, and Hartnell's name appeared amongst those of his fellow Doctors in the end credits. During the 50th anniversary in 2013, Hartnell appeared in TV: The Name of the Doctor by way of manipulated stock footage and audio, allowing the actor to posthumously share dialogue with Jenna-Louise Coleman playing a "splinter" of Clara Oswald; later in 2013, Hartnell was again represented via stock footage in TV: The Day of the Doctor, but with John Guilor providing newly recorded dialogue.

William Russell voiced the First Doctor for the Big Finish Doctor Who audio story The Light at the End.

whoisdoctorwho.co.uk
The website whoisdoctorwho.co.uk had a list of sightings of the Doctor from which people had ostensibly been submitting to Clive, a conspiracy theorist character from TV: Rose.

A submission from an 81-year-old Mrs. Smith mentions her working as an usherette at the Ritz Cinema in Totter's Lane, which was later demolished and turned into flats. In 1963, she encountered a version of the Doctor with white hair, and a younger girl Mrs. Smith presumed was his granddaughter. While watching a film on the fall of Rome at the cinema, she recalled the Doctor continuously tutting and muttering that it wasn't historically accurate. She "gave him a piece of [her] mind and sent him packing". He stormed towards the old junkyard and she never saw from him again. She presumed Clive's Doctor posted on the website, the Ninth Doctor, was some sort of relation, rather than another incarnation like the first.
