Guiding them through the trials and tribulations of adolescence was Edna Garrett, their no-nonsense, but always understanding, housemother."The AP adds, "Edna Garrett provided kind if sometimes wry counsel to her charges (played by young co-stars including Lisa Whelchel, Nancy McKeon and Molly Ringwald) on a series that was praised for dealing with such sensitive issues of teenhood as sex, drug use, eating disorders and peer pressure."Rae was nominated for a Primetime Emmy for The Facts of Life in 1982.Although the role of Mrs. Garrett is what made her famous, Rae appeared as Woody Allen's mother in the film Bananas (1971).
