Barbara K. Firestone, philanthropist and wife of industrialist and former ambassador Leonard K. Firestone, has died of cancer. She was 70.
Mrs. Firestone, a third-generation San Francisco native, died Tuesday night at her Thunderbird Country Club home in the desert city of Rancho Mirage, family spokeswoman Tracey Priestley said Wednesday.
Mrs. Firestone had been active in the creation of the Betty Ford Center at Eisenhower Medical Center in Rancho Mirage, about 100 miles east of Los Angeles. The bookstore at the alcohol-chemical dependency treatment center was named for her, Priestley said.
Mrs. Firestone was born Barbara Knickerbocker in San Francisco and was known to friends as Nicky.
Her first husband, Stuart A. Heatley of San Francisco, died in 1964, and she married Firestone in 1966 and moved to Los Angeles. Firestone's first wife had died in 1965.
