Elizabeth M. Schilling, granddaughter of San Francisco’s first Episcopal bishop and a key figure for decades on city hospital boards, died November 24 at the home of her son in Coeur d’Alene, Idaho, at the age of 74.

Born in Boston, Ms. Schilling was a graduate of Vassar College and Harvard Medical School, where she earned a master’s degree in medical science.

After her marriage to Rudolph Schilling in 1946, she moved to Woodside, where she and her husband raised three children.

She started as a volunteer at Children’s Hospital and became a director. As president of the board, she helped establish the first hospital-based health maintenance organization in the Bay Area in 1975.

Ms. Schilling served on several other health-related boards, including the California Hospital Association, the Professional Services Review Organization, the Hospice of San Francisco, the San Francisco Comprehensive Planning Agency and the Mercy Health Care Organization.

At the time of her death, she was co-chairwoman of the board of counselors at the California Pacific Medical Center.

She served on numerous other boards, among them the board of trustees of the California Academy of Sciences.

She is survived by her brother, William N. Mills of San Francisco; a daughter, Alexandra S. Friedman of Hartford, Conn.; a son, Edward Nichols Schilling of Coeur d’Alene; and six grandchildren. She was preceded in death by her husband and a son, Charles H. Schilling.

Memorial services will be held at St. Luke’s Church in San Francisco tomorrow at 11 a.m.
