Founders
The Andrew W. Mellon Foundation was formed on June 30, 1969, through the consolidation of two existing foundations—Avalon Foundation and Old Dominion Foundation.
The Avalon Foundation had been established in 1940 by Ailsa Mellon Bruce, daughter of Andrew W. Mellon. The Old Dominion Foundation had been established in 1941 by Paul Mellon, son of Andrew W. Mellon. When the two foundations were consolidated, the Foundation was renamed The Andrew W. Mellon Foundation to honor their father.
