These stories were fictionalized reminiscences of her relationship with her mother and were published not only in the United States but also around the world after Reader's Digest published the stories in many international editions.
In the 1970s, Mrs. Coogan became editor in chief of what is now Nursing '97 magazine. She later became vice president of editorial affairs of Springhouse Corp., the magazine's publisher. Under her editorial leadership, the magazine became the second-largest journal for nurses in the United States and was frequently nominated for best magazine in its circulation category.
After she retired in the early 1980s, she and her husband continued to live in Roxborough and Manayunk, until last summer, when they moved to Wake Robin Retirement Community in Shelburne, Vt.
Her husband died in September.
In an era when it was difficult for women to achieve their full potential, said her daughter, Nell Ekman, Mrs. Coogan stood out both as a creative writer and as an outstanding editor. Her rare combination of heart, intellect and strength of character made the woman behind ``Kate's Girl'' loved by all, her family said.
In addition to her daughter, she is survived by a son, Kevin, and three grandchildren.
A memorial service was held yesterday in Vermont.
