BiographyEdit

Early lifeEdit

Catherine Elizabeth Halsey was born on Endymion on March 19th, 2492. Not much is known about her early life, but what little is known gives a glimpse of what would be a promising career. In her own words, she was "...smarter than her parents, always reading, talking, learning, and eager to share her knowledge with anyone who would listen."^[8] By 2507, at the age of 15, Dr. Halsey was already writing her second Doctoral Thesis paper, in which she discussed archaic line commands.^[9] It is also known that at some time in her early life, she supervised the creation of the template for third-generation "Smart" AIs.^[9] She was Vice Admiral Ysionris Jeromi's star pupil as well.^[10] In August 2510, Halsey purchased a small, hardback journal in a shop on Reach, near the base she was stationed in. Halsey used the journal as a medium through which to express her thoughts and concerns, as well as important research notes, and would do so for another forty-two years, until she abandoned it during her escape from Sword Base. The journal was later recovered by ONI in 2553, and was designated top secret.^[11]

During their survey travels for the Spartan-II candidates, Halsey grew attached to Jacob Keyes. The two were involved in a romantic relationship in the early 2520s, and in 2525, Halsey gave birth to Miranda and raised her for a few years, when on July 12, 2531, Miranda's father agreed to take her in, raising her on Luna. Halsey would later have a falling-out with Miranda, who would later change her legal name to her father's and refuse to speak to Halsey for several years.^[11]

SPARTAN-II ProgramEdit

Main article: SPARTAN-II Program

"This boy could be more useful to the UNSC than a fleet of destroyers, a thousand Junior Grade Lieutenants -- or even me. In the end, the child may be the only thing that makes any difference."

— Catherine Halsey speaking to Lt. Jr. Grade Jacob Keyes, referring to John-117 in Elysium City.

Dr. Halsey served as a scientific adviser for to the Office of Naval Intelligence from 2515 to 2522, when she was made chief scientist.^[1] She made huge contributions to many ONI Section III projects, including the creation and deployment of AI constructs. She also created and initiated the SPARTAN-II project as well as the development of the MJOLNIR armor system. These all proved to be important developments for the UNSC, and to the continued survival of mankind.

In 2517, at the age of 25, Dr. Halsey became the creator of the SPARTAN-II project, and she built a set of rigorous genetic requirements that any potential candidate of the program was required to meet. From these requirements, she identified 150 candidates, but ONI would only give her enough funding to train 75 of them. She met each of the candidates and determined who the 75 would be. She had Junior Lieutenant Jacob Keyes accompany her during the interview of John-117. She then had the children secretly brought to the planet Reach for training. The 'recruited' children were replaced with flash clones, which die at a certain time, due to various neurological and physiological diseases.

With the assistance of Chief Petty Officer Franklin Mendez and the AI Déjà, she proceeded to train the Spartans. She supervised their augmentation procedures, combat training, and education, and studied the effects of the Spartan lifestyle on the children. She kept in close contact with them all throughout their lifetimes, from her base under Reach. Annoyingly, she was always able to tell them apart from each other, even under half a ton of MJOLNIR battle armor. Dr. Halsey always used their first names, never their ranks or Spartan tags. This revealed that she had a huge amount of respect for, and from, the Spartans; she was also able to order them around and the Spartans referred to her as "Ma'am", which is another example of how they respect her, not to mention that they also regard her as a sort of a mother figure. She also knew many of the Spartans' closely held secrets, having taught many to them as children, such as the Oly Oly Oxen Free security tune.^[2]

Involvement during Human-Covenant WarEdit

Battle of HarvestEdit

Main article: First Battle of Harvest

After first contact with the Covenant, Dr. Halsey accessed LCDR al-Cygni's ONI Sloop Walk of Shame's data archive. During Dr. Halsey's investigation, she began researching the last conversations of the A.I. Mack, and his choice of misspelled Shakespeare during his last days of rampancy. Dr. Halsey was conducting her research under the name Charlie Hotel.^[12]

CaptureEdit

Main article: Raid on the Third Fleet of Glorious Consequence

In 2544, Halsey was captured by a Covenant fleet during the Battle of Miridem, while cryogenically frozen.^[13] A team of Spartan-IIs, consisting of John-117, Kelly-087, Frederic-104, Solomon-069, and Arthur-079 were sent to rescue her with Open Frame 92/Extra-Vehicular Activity vehicles. Knowing Halsey's value to both the UNSC and the Covenant, Luro 'Taralumee, the Covenant fleet master, planted decoys in several CCS-class battlecruisers.

Solomon was killed by one of these decoys, which turned out to be an Antimatter Charge giving off a false signal. Arthur was also killed, crushed between two cruisers while covering Kelly-087 from multiple Seraph fire. After finding the ship Halsey was on, John, Kelly and Fred fought through large numbers of Covenant forces, though Fred and Kelly were separated during the fight, leaving John to think them dead. John finally reached Halsey and rescued her from a cryo pod, but they were stopped by then-Major Thel 'Lodamee. Halsey then watched as John engaged the Elite in an Energy Sword duel. However, the Fleet Master in command of the Covenant fleet detached the section of the ship they were in, returning Thel mid-fight via Gravity Lift and jumped into Slipspace.

Halsey and John soon made it to a Covenant Escape Pod, but were engaged by Seraph-class Starfighters. She was visibly frustrated at the slow speed of the pod, going so far as asking John to take out the Seraphs with just his assault rifle. They were soon rescued by Fred and Kelly, who had captured a Seraph fighter, and later by the stealth ship that had deployed the Spartans. Later on the stealth ship, Halsey comforted John as he swore not to lose another Spartan.

Fall of ReachEdit

Main article: Fall of Reach

On July 26, 2552, Halsey was working under ONI's Sword Base when it became under attack by a Covenant corvette. After the destruction of the corvette, she called Noble Team to her laboratory for debriefing, where she learned of the death of her subordinate, Laszlo Sorvad, stabbed through the abdomen by an Elite survey team. After arguing with Carter-A259 over Noble's failure to apprehend the Elites' leader and Catherine-B320's attempted access of restricted files, she learned of the nature of Sorvad's "latchkey" discovery, a way to decipher data found in an underground Forerunner facility beneath Sword Base. After dismissing Noble Team, she began the decryption process of the "Latchkey" data in the Forerunner complex.

On August 3, Halsey split up Cortana, assigning her "copy" to work on the decryption of the Forerunner data in the underground facility below Sword Base, while her other half would prepare for the Spartans' mission; Operation: RED FLAG. Cortana also took the form of Halsey at a younger age. When the UNSC Iroquois arrived at Reach from Sigma Octanus on August 12, Halsey visited the ship. During her visit, Captain Keyes came to see her, and they discussed their daughter Miranda, the Keyes Loop, the Spartans and Operation RED FLAG. Later in the day, she visited Camp Hathcock to see John-117 after his debriefing. On August 27, she met most of the remaining Spartan-IIs at the FLEETCOM military complex in the briefing for RED FLAG.^[11]

Later, Noble returned after receiving orders to destroy Sword Base. Halsey once again called Noble Team to her, revealing Noble's true orders to them: to transport a package containing "mankind's best chance for survival" to the Halcyon-Class Cruiser Pillar of Autumn, holding position in the Aszod ship breaking yards. After Noble's successful defense of her lab while she prepared the package, she entrusted Noble 6 with the package: a fragment of the AI Cortana, now uploaded with the information from the Forerunner facility. Once she made certain that Noble Six would deliver Cortana to the Autumn, she left for CASTLE Base under the escort of Jun-A266 while the remaining Noble Team members delivered the package to the Autumn.^[11]

Dr. Halsey then continued working in ONI's CASTLE Base. She volunteered to remain behind to ensure that all UNSC technology was secured from possible capture.^[14] She initiated Operation: WHITE GLOVE, destroying several AIs (including Cortana's "older sister" Kalmiya) to keep the Covenant from accessing UNSC databases. With expectations that the Covenant would glass the planet and knowledge that even if they didn't, she would be facing an entire army of Covenant ground forces, it was clearly an offer of sacrifice.

However, this changed when Spartans Fred-104, Kelly-087, Vinh-030, Isaac-039, and Will-043 appeared at the entrance to CASTLE Base. With the firepower to potentially fight their way out, the possibility of surviving CASTLE Base's destruction became available. She gave emergency aid to the Spartans for their injuries, but a data anomaly detected by her accompanying AI, Kalmiya, attracted Dr. Halsey's attention.

The data had been accessed by Araqiel, an AI that worked for Colonel Ackerson, one of Dr. Halsey's main competitors within ONI. After tracing the data access, Dr. Halsey stumbled across the AI, left behind by its master. Araqiel then proceeded to threaten her (he went as far as telling her he would fill the room with poison, and that she would be reported). She started typing in "archaic line commands" to access his code directory and personal fail-safe. She then shut him down.^[15] After shutting him down, she proceeded to read through Ackerson's files and discovered a number of things including the location of Onyx, evidence of the SPARTAN-III program and a map of the mining tunnels CASTLE base had been built upon. The latter particularly interested the Doctor as the file had been classified at X-Ray level, making the file abnormally important for ancient maps. From this, she deduced that there was something of importance under the mountain.

Assuming that at the very least these maps provided a backdoor, she chose to move the Spartans out of the base and into the mineshafts. She then triggered CASTLE Base's self-destruct mechanism and activated the fail-safe on Kalmiya. With the Spartans in tow, they moved into the mineshafts.

Over the course of the next five days, the Spartans and Dr Halsey searched the mines, looking for either an exit or what Dr. Halsey would dub "the most important discovery of the millennium". On the fifth day, Fred discovered an entrance into a large Forerunner structure, and within, the Forerunner Crystal. However, the acquiring of the crystal sent a spike of neutrino radiation, attracting the attention of the Covenant. Their location was now threatened by Covenant forces.

Following a Covenant attack, Halsey and her team retreated into a hallway and sealed off the entrance, losing contact with Isaac and Vinh in the process. However, they quickly discovered that the hallway was a dead end. It is presumed that Halsey and the surviving Spartans remained stranded at this location for some time.

Days later, a group of Spartans, including John-117, rescued Dr. Halsey and the remaining Spartans and evacuated them from Reach to the captured Ascendant Justice.

Dr. Halsey later saw the importance of destroying this artifact after it caused a Slipspace anomaly that nearly resulted in the destruction of the Ascendant Justice. After escaping Reach, the group fled to the asteroid belt that the Spartan's first mission had been in. While there, she stole the rebel governor's spacecraft and, along with Kelly-087, whom she had sedated, escaped into Slipspace. When asked by Admiral Whitcomb as to the reasons for her actions, she gave a simple UNSC code "Three-Nine-Two", which meant that she was on a high priority mission. She entrusted the Forerunner Crystal to Corporal Locklear, telling him to keep it safe, hidden, and to do whatever it took to keep it from falling into enemy hands, otherwise the Covenant would be able to go a hundred times faster in Slipspace. The Corporal destroyed the crystal, which is not totally against her orders, and died as a result of the explosion created by the destruction of the Forerunner Crystal. The Covenant later recovered a few fragments.

In the aftermath of the battle, she was presumed dead by the Office of Naval Intelligence and honoured, with other personnel, on a plaque at ONI Alpha Site. It can be assumed the SPARTANs and Johnson neglected to report her retrieval from CASTLE Base then her following kidnap of Kelly and apparent desertion from the UNSC. Another possibility is that her name was added to the wall after the Battle of Reach but before the Spartans returned to Earth. It could also be that the ONI did not want anyone to know that she had kidnapped Kelly, so they covered the incident up by saying she had died.

Battle of OnyxEdit

Main article: Battle of Onyx

Dr. Halsey and Kelly eventually arrived at Onyx, while reuniting with SCPO Mendez and eventually her remaining SPARTAN-II's and the SPARTAN-III's. She helped decipher the mystery of the planet. At first, she tried to maintain secrecy about her intentions out of habit, until Kurt-051 confronted her about it. She admitted that she was not actually looking for weapons, but rather the secret Forerunner Shield World ,which she believed to be equivalent to a bomb shelter, and would be capable of keeping the remaining Spartans safe to evade all current war and let them live to fight another day. Her relative expertise with Forerunner technology was vital to the survival of the UNSC forces on the planet. At the end of the battle, she, along with Mendez, Blue Team, and the Spartan-III survivors, found herself inside the Shield World, which she believed was actually a Micro Dyson Sphere.^[16]

In Halo: Glasslands the story is continued, finding that for several days, possibly weeks, she is stuck inside the shield world, with Blue Team, Chief Mendez, and the last of the Spartan-III 's, until she is rescued by ONI . During the time she was trapped inside the Dyson sphere she tranlsates many Forerunner symbols, in the hope of finding Lucy-B091, who went missing shortly after they began to explore a Forerunner structure inside the Micro Dyson Sphere . Several days later, Lucy returns with a Huragok named Prone to Drift who showed her how to get back to her team. Dr. Halsey then starts asking Prone several questions as to where they are, and how to get a message out to other humans outside the sphere . Prone states that he cannot let her do that because there is an unknown entity (presumably a human ship) outside the Micro Dyson Sphere^[17], and he refuses to give Halsey access to the communications until he knows it's safe. After an unsuccessful attempt to persuade Prone to give her access to the comms, Dr. Halsey decides to ignore him and tries to access the communications system herself but before she can touch the controls Prone slaps her hand away, stating again that he cannot allow her access. The slap enrages Dr. Halsey and she starts to yell and threaten Prone, who is forced into a corner trying to protect himself. Lucy-B091 pulls Halsey back and punchs her in Prone's defence. After much talk between the humans, Lucy speaks to Prone and convinces him that it is safe outside the Dyson Sphere, and Prone lets Dr. Halsey send a message outside the Dyson Sphere. The message is recieved by ONI operatives, who then relay the message to Margaret Parangosky, the head of ONI, who sends a message to Dr. Halsey requesting the Huragok bring the Dyson Sphere into normal space. In her transmissions to ONI while the Huragok prepare to bring the shield world into normal space, Dr. Halsey tells of the Forerunner artifacts that could be used by humankind such as the precision slip space technology. After the shield world is brought into normal space, Kilo-5 is sent in to arrest Catherine Halsey for the crimes she has committed (hijacking ships and kidnapping a Spartan). After her arrest, she is sent to Ivanoff Research Station which is monitoring Installation 03 , where Margaret Parangosky informs her that as far as society is concerned, Catherine Elizabeth Halsey died on Reach, and from now on, she will be working in the research facility for as long as Parangosky and her successor see fit.^[18]

However, as seen during the cutscene on the mission Lone Wolf, it seems Dr. Halsey visited Reach and gave an Eulogy to Noble 6.

PersonalityEdit

Little is given in the terms of social activities or even a list of friends. Her intelligence is unquestionable as well as the loyalty and respect she receives from the majority of her comrades and her Spartans. However, as seen in Halo: First Strike, her judgment is not always correct, although bearing the guilt of the Spartan program, her sense of right and wrong has differed greatly. It is obvious that she truly cares about her Spartans. She has a notable fondness for classical music, especially Debussy, and often asks nearby AIs to play select pieces as she works.^[19]

What can be gleaned is that she preferred the company of AIs, and, although she may be angered easily at being mentally defeated, always appreciates the simplicity of them. None more than Cortana, who was actually created from a flash clone of her own brain. She is an atheist, lacking belief in the existence of any god.^[20]

GuiltEdit

Dr. Halsey carried extraordinary guilt because of the SPARTAN-II project, feeling that she had exploited the children and destroyed their lives, a feeling which was later passed to Cortana. Though she continued to support the spartans and gained monumental prestige for her efforts, she also felt responsible for each one who died. She never could quite justify their exploitation as a "necessary sacrifice." She also had considerable respect for the Spartans, and addressed them by their first names (even with their armor on), which seemed to greatly annoy them.^[21]

Her feelings of guilt were made evident by the fact that she often referred mentally to "sacrificing the few to save the many," though this rarely worked to soothe her conscience. By the time she was rescued from Reach by the Ascendant Justice, she simply wanted to save as many lives as she could, believing that the war was not one that the UNSC could possibly win. While she knew that her own Spartans, the SPARTAN-IIs, couldn't be persuaded to turn from the war, she believed the SPARTAN-IIIs may not yet have been fully determined to win the war, and she set out to try and weaken their resolve to fight.

John-117Edit

Halsey also had somewhat of a unique relationship with John-117. Some of this may stem from him being the first subject she observed, but she had a great fondness for him and he was her favorite Spartan. Halsey told Cortana she considers him the luckiest and best of the Spartans and also apparently finds him attractive given her reaction to Cortana's comments on that. Halsey was responsible for John's first promotion to Squad Leader as a result of her acknowledging his leadership skills and suggesting it to Mendez. Halsey also had John's full trust and he always did his best to never undermine her authority.

Halsey decided to test her favorite Spartan's sense of ethics by handing over data concerning Avery Johnson and how his Boren's syndrome made him immune to the Flood. She knew that if the data was handed over to ONI, Johnson would likely be killed and dissected in order to find a cure to the Flood infection. She estimated that there is a billion to one shot that they could have replicated Johnson's condition, but conversely ONI would do it to save Humanity from a greater foe.^[22] At first, John chose to sacrifice Johnson in order to try and save millions of people out of his duty to protect all of Humanity. However, John reconsidered and eventually destroyed the data due in part to the sacrifice of Vice Admiral Danforth Whitcomb and Lieutenant Elias Haverson^[23], believing that one man could make a difference as opposed to sacrificing him for the greater good.

TriviaEdit

Halsey is voiced by Jen Taylor,^[24] who also voices Cortana, reinforcing the connection between the two characters. This is also the case in Halo Legends, where Shelley Calene-Black voices both Halsey and Cortana.^[25]
In Halo: First Strike, it is stated that Dr. Halsey was not keen on losing, as seen when she kept losing at a game of Twenty Questions with her training SPARTANs and soon quit playing.
She had a knack for embarrassing the SPARTANs with the way she was able to tell them apart through subtle habits in their postures, despite their identical MJOLNIR armor, something no other non-SPARTAN was able to do. Unlike most others, Halsey never referred to the SPARTANs by their numerical designations, but by their names. However, she referred to Daisy-023 as "Twenty-Three" when trying to convince Daisy to return to the program.
She had a bad habit of keeping a messy office and drinking cold coffee, tending to prepare the drink and then become distracted by work, only remembering it hours, sometimes days, later.^[26]^[27]
Halsey served as a mentor to Professor Ellen Anders at some point prior to 2531, though they apparently had a major falling out, as noted by Anders in the manual, saying "Why mention Halsey here? She hated me and I hated her."^[28]
After the Fall of Reach, she was presumed dead by the Office of Naval Intelligence, although no body was found. She was mentioned in a memorial plaque inside the ONI Alpha Site on Earth.^[1] This is odd, considering that John-117, Will-043, Linda-058, Fred-104, Cortana, and Avery Johnson knew she had fled with Kelly-087. However, it is possible that the memorial plaque in question was erected before this news reached Earth.
Two of Dr. Halsey's statements in The Package are references to similar statements made in the first two Halo games. She tells John-117 that she slept well "No thanks to their driving," which is echoed in Halo: Combat Evolved when he tells Cortana he slept well no thanks to her driving. She also tells John, "Don't make a girl a promise...if you know you can't keep it," which Cortana would tell him in Halo 2.
Halsey's appearance changes drastically from The Package to Homecoming. In The Package, at which point she is aged fifty-two, she is inexplicably depicted as a fairly young woman with short, blond hair and no glasses. This may or may not have been reflected in the later appearance of Cortana, who was created from the replicated neural pathways of Dr. Halsey herself. Her appearance in Homecoming however, is slightly closer to her description from the books. It should be noted that various concepts in The Package, and Halo Legends in general, result from artistic license. Her appearance in Halo: Reach is much more in line with the description she received in the novels.
Catherine Halsey is also a character in the novel the Fountainhead. In the novel Halsey progresses into becoming an altruist, thinking of nothing other than the greater good of the majority. In this sense, she is an opposite of the Halsey of the Halo universe; Dr. Halsey begins by sacrificing the Spartans to buy the UNSC more time, but then changes her mind and does everything she can to save the Spartans, regardless of what happens to the rest of humanity.
Dr. Halsey's personal journal is included in Halo: Reach's Limited and Legendary Editions, for which Bungie worked directly with Eric Nylund to make sure it is canonically accurate.
In Halo: Reach, you can access Dr. Halsey's lab in which there is a dedication to some of the internet's parodies such as Red vs. Blue and the Halo: CE Jump video. To access this easter egg, you must play on legendary with at least two people on the package, then using the jetpack, you find the hidden switch, activate it and open a door on the far side of the map, releasing seven sanghelli generals. After briefly waiting in this room, you will be transported to a long hallway, walking down this hallway will bring you to her lab.
The first five numbers on Halsey's security card (included in personal journal) are 10141. The sum of these numbers is another reference to "7".
It is unusual that in Ghosts of Onyx Halsey seems to know nothing about the Spartan III's even though she met Noble Team on Reach which consisted of Spartan III's, save for Jorge, a Spartan II. However, she may have thought that the Spartans of Noble Team were a new generation of Spartan IIs created without her knowledge, due to the fact that they wear the Spartan II's signature MJOLNIR armor. It was the theft of Colonel James Ackerson's files in CASTLE Base that allowed her to deduce the existence of a new version of Spartans.
There is a discrepency between sources as to Halsey's hair is blonde or black.
