Pauline Phillips, the woman known to the world as "Dear Abby," died Wednesday at age 94, a rep for Phillips' daughter Jeanne confirmed to ABC News.
Phillips struggled with Alzheimer's disease for years. By the mid-1990s, she was already co-writing her column with her daughter Jeanne and as the illness progressed, she passed on the torch completely. The original Dear Abby officially retired in 2002.
TMZ quoted Jeanne Thursday, saying: "I have lost my mother, my mentor and my best friend. My mother leaves very big high heels to fill with a legacy of compassion, commitment and positive social change. I will honor her memory every day by continuing this legacy."
