Charles Francis Xavier was born in New York City to the wealthy Dr. Brian Xavier, a well-respected nuclear scientist, and Sharon Xavier. The family lives in a very grand mansion estate in Westchester County because of the riches his father's nuclear research has brought them. He later grows up to attend the University of Oxford, where he earns a Professorship in Genetics and other science fields, and goes on to live first in Oxford and then London for a number of years. Crucially, as he enters late adolescence, Xavier inherits the mansion-house he was raised in, enabling him not only to continue to live in it, but also to turn it in to Xavier's School for Gifted Youngsters, which he begins together with the first of the X-Men.
