(X-Men I#12 - BTS / X-Men: Manifest Destiny#3/2 - BTS) - At some point, Brian inherited the Xavier family home and fortune, the large Neoclassic mansion. The mansion was constructed sometime between the late 1700's and early 1900's after his ancestors Charles and Marcia Graymalkin had settled on the land.

(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. Brian found his wife, learning she had a partial miscarriage.

(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-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 (writer).

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.
