Alison’s son Welles was 24 years old on 9/11 and saved at least 12 people in the South Tower before it collapsed on him. She didn’t know about his heroic actions that day until several survivors said that a stranger wearing a red bandana saved their lives, and she knew that it had to be her son who always carried one. He’s famously been called “The Man in the Red Bandana” ever since.
