Ms. Warrick, known to fans of ABC's "All My Children" as Phoebe Tyler Wallingford, died in her Manhattan home of complications from pneumonia, her manager told The New York Times. She was 88. In the classic 1941 film, "Citizen Kane," she played Charles Foster Kane's wife, Emily, niece to the president. She made only three appearances on Broadway, in Miss Lonelyhearts (1957), the musical Take Me Along (replacing Eileen Herlie) and in the 1974 revival of Irene.
The native of St. Joseph, MO, was no stranger to the stage, however, having studied acting with Antoinette Perry and Brock Pemberton, and played in many stock productions — as early as 1933 at the University of Kansas. In 1960 she was Anna in The King and I at the Music Fair in Toronto. Her work in film, radio and theatre was eclipsed by her work on "All My Children." As rich and grand Phoebe, she appeared on the program since 1970.
Ms. Warrick was married five times. Survivors include three children, Karen Langenwalter, Jon Rolf and Robert McNamara; a grandson; and six great-grandchildren.
