Frances L. Scaife, born Frances Olga Larimer on October 7, 1927, in Pittsburgh, Pennsylvania, was an American socialite and philanthropist closely associated with the wealthy Mellon banking family through her marriage to Richard Mellon Scaife, heir to the Mellon fortune, on April 14, 1950. The daughter of a prominent Pittsburgh businessman, she grew up in the city's elite circles and was placed at the center of high society, residing in opulent estates like Rolling Rock Farm in Ligonier, Pennsylvania. She had two children: a daughter, Sarah, who died in infancy in 1952, and a son, David, born in 1957. Throughout her marriage, she was actively involved in charitable causes, supporting institutions such as Carnegie Mellon University, the Pittsburgh Symphony Orchestra, and various cultural and educational organizations in Pittsburgh, often aligning with her husband's giving through the Scaife Foundations. Her marriage ended in a contentious divorce in 1990, with a settlement reportedly worth around $200 million. Post-divorce, she continued her philanthropic work, resided primarily in Pittsburgh, and was involved in family matters, including a 2006 lawsuit against her son David. Frances L. Scaife passed away on February 16, 2018, at the age of 90, leaving a legacy as a key figure in Pittsburgh's philanthropic and social elite.
