MINNEAPOLIS — 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.

Her column is printed daily in the Butler Eagle.

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.

Ann Landers died in June 2002. Later that year, the family revealed that Phillips had been diagnosed with Alzheimer’s disease. By then Phillips’ daughter, Jeanne Phillips, who had helped her mother with the Dear Abby column for years, was its sole author.

Aside from the Dear Abby column, which appeared in 1,000 newspapers as far off as Brazil and Thailand, Phillips conducted a radio version of “Dear Abby” from 1963 to 1975 and wrote best-selling books about her life and advice.
