Richard Mellon Scaife, the billionaire publisher and heir to the Mellon banking and oil fortune who died on July 4 at the age of 82, has left his art collection to two Pennsylvania museums, the Associated Press reports.

The collection is to be split between the Brandywine Conservancy and Museum of Art near Philadelphia and the Westmoreland Museum of American Art outside Pittsburgh. While Scaife's will allows the two museums to decide how to divide the collection, it stipulates that Westmoreland receive at least eight paintings by John Kane, an artist who lived most of his life in western Pennsylvania and whose works depicted Pittsburgh during the industrial boom. Attorney H. Yale Gutnick, who represents the Scaife estate, described the collection of works by mostly American artists as expansive but said he could not estimate its value.

Scaife also left Brandywine a conservancy built on the grounds of his childhood home in western Pennsylvania, along with $15 million for its management. The fifty-room house on the site was razed in the 1960s and the land was turned into a conservancy, where Scaife grew flowers year-round in a greenhouse.

The owner of Trib Total Media — which includes the Pittsburgh Tribune-Review and five other daily newspapers — was known for his support of conservative causes. The will directs that assets he inherited from his parents be divided between two foundations and that the rest of the estate go to a revocable trust.

"Art of all kinds is one of the greatest joys, great treasures, and most worthwhile philanthropies of my life and my family's," Scaife wrote in a column in June. "As I near the end of my life, I hope many others continue to support America's museums, artists, and art programs so future generations can enjoy and benefit from them."
