Alan Butler Scaife (1900-1970) was an American banker and executive prominently involved in the financial institutions of the Mellon family, one of the wealthiest industrial dynasties in the United States. Born on March 14, 1900, in Pittsburgh, Pennsylvania, to Allan Scaife and Sarah H. Butler, he grew up in the city's affluent circles. He was the father of Richard Mellon Scaife, who later inherited significant portions of the fortune and became a major conservative philanthropist and media proprietor. Scaife built a career in finance, serving as a vice president at T. Mellon & Sons, a cornerstone of the Mellon banking operations, and held executive positions in other family-affiliated ventures, contributing to the management of their extensive holdings in banking, aluminum, and oil sectors. In 1930, he married Sarah Cordelia Mellon, daughter of Richard Beatty Mellon, which solidified his position within the inner circle of this powerful clan. The couple had two children: Richard Mellon Scaife and Cordelia Scaife. Scaife's life was characterized by discretion and loyalty to the Mellon interests, avoiding public controversies, though his family's wealth drew occasional scrutiny in broader discussions of American industrial elites. He died on April 12, 1970, in Pittsburgh, leaving a legacy tied to the perpetuation of the Mellon financial empire.
