(X-Men I#1 - BTS) - Brian and Sharon Xavier worked on the first a-bomb project. (see comments)

(X-Men I#12 (fb) - BTS) - Having become a wealthy and famous geneticist, Brian met and married Sharon. The two lived in the Xavier Mansion.

(New X-Men I#121 (fb) ) - Sharon became pregnant with twins that would later be known as Charles Xavier and Cassandra Nova. However, the twins were already showing signs of genetic mutation in the womb. Cassandra manifested herself as an entity known to the Shi'ar as "Mummudrai," the spirit opposite of a person. In this case, that of her own twin brother Charles. Exposed to his polar opposite, Xavier instinctively used his telepathy for the first time. After getting a rudimentary grasp of what she was, his own personal worst enemy, he tried to kill her with a mental assault. The ensuing internal struggle was so great Sharon was overwhelmed by the sensation, causing her to lose her balance while going up a flight of stairs after which she fell down the stairs.

(X Lives of Wolverine I#1) - When the night had fallen, Sharon went into labor at the Xavier Estate. While the midwife guided Sharon through the process Brian nervously drank a brandy at the estate's fireplace but decided a breath of fresh air was needed in order to calm his nerves. However, when Brian stepped outside he was attacked by Bowers the gardener. In reality the gardener had been possessed by the time traveling evil mutant Omega Red who'd been tasked by Russian Mikhail Rasputin to murder Charles Xavier's relatives throughout time. Just then Wolverine appeared, who'd been send through time by Charles Xavier and Jean Grey to stop Omega Red. Wolverine quickly ordered Brian to grab his hunting rifle and keep his family save while he would deal with the possessed gardener.

    Meanwhile, Sharon had given birth to the stillborn Cassandra. While the midwife carried the stillborn away Sharon screamed out in pain which in turn alarmed Brian who, now joined by the butler, loaded his rifle. However, just as Brian made his way upstairs Omega Red took possession of the butler and tried to shoot Brian. In an act of self defense Brian then shot, and killed the butler.

    The midwife assured Sharon they would mourn Cassandra later but she would need to deliver her second baby. But just as Brian rushed into the master bedroom Omega Red took possession of the midwife and began to strangle Sharon. A shocked Brian quickly pointed his rifle at the midwife but Omega Red used one of his tentacles to grab the rifle and knock Brian unconscious. Next, Wolverine bursted through the door and attacked the midwife while Sharon gave birth to Xavier. Determined to defend her family, Sharon held baby Xavier in one arm while holding the rifle in her hand threatening Wolverine and Omega Red to leave their home. Unaware Wolverine had come to rescue them she shot the mutant point blank after which the possessed midwife grabbed Sharon. Having regained his consciousness Brain jumped the midwife from behind, scratching her eyes out. Wolverine then took hold of baby Xavier, luring the midwife towards the windows until he jumped aside at the last moment while the midwife fell to her death, ending Omega Red's assassination attempt.

(X Lives of Wolverine I#4 - BTS) - In an effort to lessen their impact on the timeline, Charles Xavier and Jean Grey unleashed a mile-wide psionic blast to make those affected forget everything that had transpired. The psionic blast was made to feel as if this affected by it would feel like their rising from a nap they can't quite remember.

(New X-Men I#121 (fb) - BTS) - Though the doctors pronounced her stillborn, Cassandra in fact survived and spent the next years as a growing mass of cells in a sewer, building a new body for herself and planning her revenge on her brother.

(X Lives of Wolverine I#4 - BTS) - At some point in time Brian Xavier was grafted into the marines to aid during World War II. Brian became a luitenant and was stationed on a large ship outside of Japan.

(X Lives of Wolverine I#4) - In 1945 while working on a U.S. warship full of marines near Japan, Brian noticed three Japanese fighter planes heading their way. One of the planes was flown by Captain Kenji Oyama, possessed by the time traveling Omega Red determined to crash the plane full of explosives into the U.S. warship. Luckily, Wolverine arrived in a Canadian plane and was able to shoot the Japanese out of the skies, saving Brian and the marines.

The psionic blast was made to feel as if this affected by it would feel like their rising from a nap they can't quite remember.

(X-Men Legacy I#212 (fb) ) - Famous geneticist Dr. Nathan Milbury, secretly Mr. Sinister, gathered X-gene positive people, planning to have them breed in order to investigate the genetic potential of their offspring. Setting up an elaborate, partially underground lab in a planned nuclear research facility in Alamogordo, New Mexico, he worked along with Brian Xavier, Kurt Marko, Alexander Ryking and Irene Adler, who served as the project's administrator. This group of geneticists would one day be known as the Black Womb Program.

(X-Men II#12 (fb) - BTS) - Brian was believed to be a nuclear researcher at the Almagordo nuclear research facility to cover for their government studies in genetic mutation.

(X-Men Legacy I#212 - BTS) - Dr. Milbury eventually rechristened the Black Womb project, calling it Cronus after the titan of Greek mythology.

(X-Men II#13 (fb) - BTS) - Xavier also worked on the S.H.I.V.A scenario with Alexander Ryking and Dr. Kurt Marko under the eye of Major Arthur Barrington. A new type of assault robot, designed to improve itself after every defeat, uploading its conscious into a new robot until it would become a virtually unbeatable killer.

(X-Men Legacy I#211 (fb) - BTS) - After determining young Charles' immense X-gene potential, Milbury had the boy subjected to a battery of tests about with Brian and Sharon's permission. Although Sharon wasn't too pleased, Milbury, however, assured Sharon that her son would be the next big thing that would come after humanity. Despite this assurance, she had her doubts about the integrity of the research.

(X-Men Legacy I#211 (fb) ) - While their son had a playdate with Carter Ryking another subject to Milbury's tests, Brian and Sharon once again discussed Milbury's tests. The domineering Brian could not be persuaded and told his wife he'd already made up his mind regarding the tests.

(X-Men I#12 (fb) ) - Brian Xavier died in what was described as an accidental atomic blast at Alamagordo. Now a widow, Sharon inherited the Xavier fortune. At the funeral, she was comforted by Brian's colleague and fellow geneticist Kurt Marko who told her he'd have gladly given his own life if it had meant saving Brian. Hearing this made Sharon feel as if she could depend on him.

(X-Men II#12 (fb) / X-Men Forever I#4 (fb) ) - Brian's son Charles watched over his grave while being watched by Cain Marko.

Comments: Created by Stan Lee.

In Gambit III#22 it was revealed Fred Ducan served as FBI liaison to the Black Womb genetics projects, therefore he will most likely have met and/or interacted with Brian Xavier as well.

In a flashback in X-Men II#12 we can see Brian Xavier was born 27th of August and died the 12th of October.

In X-Men I#1, Professor X stated "I was born of parents who had worked on the first a-bomb project!" This was probably the Manhattan Project. Other contributors to the Manhattan Project included Howard Stark (Iron Man I#257) and Lord Moses (Fantastic Force I#11). Samurai Steel also had sworn vengeance upon those who worked upon the Manhattan Project and their descendants (Iron Man I#257) and one must wonder if he ever clashed with Brian Xavier.

Brian affected others even after his death:
From flashbacks in X-Men I#12, we know that:
a) At Brian's funeral, when Kurt Marko was telling Sharon Xavier he would have gladly given his own life to save Brian's, Charles was standing nearby and thinking to himself that Marko was lying and that he might have saved Brian but saved himself instead!
b) Later, after Sharon had realized that Kurt had only married her for her money, Kurt ranted about how, ever since he could remember, Brian had had everything...fame, success, the admiration of the world...while he was a nobody!
c) Later, after Sharon had died, Charles overheard Cain trying to blackmail Kurt by stating that he knew it was no accident that Brian Xavier had died at Alamagordo, an accusation that seemed to really upset Kurt. Seconds later, after Charles had confronted them and Cain had caused an explosion in Kurt's lab, a fatally-injured Kurt Marko managed to get both Charles and Cain to safety and then, just before he died, Kurt told Charles that Brian's death WAS an accident but that he might have saved Brian if he had tried but that he hadn't.

Bowers the groundskeeper

  Part of the Xavier estate staff, Bowers worked as groundskeeper.

On the night when Sharon Xavier was about to give birth, Bowers was possessed by the time traveling evil mutant Omega Red who'd been tasked by Russian Mikhail Rasputin to murder Charles Xavier's relatives throughout time. The possessed-Bowers tried to kill Brian Xavier. In the end it was Wolverine (who'd been send by Jean Grey and Charles Xavier to stop Omega Red) who managed to hold Bowers off long enough for Omega Red to take possession of the butler which caused the groundskeeper to return to his normal, but confused, self.

--X Lives of Wolverine I#1

unidentified butler

  Part of the Xavier estate staff, this man worked as the Xavier's personal butler.

The butler tended to a nervous Brian Xavier while his wife was giving birth in the upstairs master bedroom. However when the mutant Wolverine appeared to stop the time traveling evil mutant Omega Red who'd been tasked by Russian Mikhail Rasputin to murder Charles Xavier's relatives throughout time, the butler and Brian loaded their guns. But while Wolverine fought the possessed-groundskeeper, Brian and the butler noticed Sharon screaming (as she was giving birth) and rushed up the stairs. However, just then Omega Red took possession of the butler and tried to shoot Brian. In an act of self defense Brian then shot, and killed the butler.
