The daughter of Bears founder George Halas, McCaskey watched the NFL go from a struggling start-up to the most powerful league in America.

Virginia McCaskey, who inherited the Chicago Bears from her father, George Halas, but avoided the spotlight during four-plus decades as principal owner, has died. She was 102. McCaskey’s family announced through the team that she died Thursday. She had owned the Bears since her father’s death on Oct. 31, 1983.

The Chicago Bears and the rest of the National Football League mourn the passing of Bears owner Virginia Halas McCaskey, who lived to the extraordinary age of 102 years-old. Virginia was a trailblazer for women in professional sports as she rose to the position of team owner amid a male-dominated profession.
