Claim: Dear Abby produced a rivalry between the two sisters and on February 13, 1987, the Chicago Tribune announced that the Ann Landers column was moving to the Tribune
Evidence: Pauline Phillips started her Dear Abby column a few months after her twin sister, Eppie Lederer, took over the Ask Ann Landers column created by Chicago Sun-Times advice columnist Ruth Crowley in 1943. On February 13, 1987, the Chicago Tribune announced that the Ann Landers column was moving to the Tribune, which had published the Dear Abby column for years. This produced a rivalry and lengthy estrangement between the two sisters.
