MINNEAPOLIS (AP) — Pauline Friedman Phillips, who under the name of Abigail Van Buren, wrote the long-running “Dear Abby” advice column that was followed by millions of newspaper readers throughout the world, has died. She was 94.

Publicist Gene Willis of Universal Uclick said Phillips died Wednesday after a long battle with Alzheimer’s disease.

Phillips’ column competed for decades with the advice column of Ann Landers, written by her twin sister, Esther Friedman Lederer. Their relationship was stormy in their early adult years, but later they regained the close relationship they had growing up in Sioux City, Iowa.

The two columns differed in style. Ann Landers responded to questioners with homey, detailed advice. Abby’s replies were often flippant one-liners.

Phillips admitted that her advice changed over the years. When she started writing the column, she was reluctant to advocate divorce:

“I always thought that marriage should be forever,” she explained. “I found out through my readers that sometimes the best thing they can do is part.”
