Mellon was diagnosed with cancer in November 1936. His health declined in 1937, and he died on August 26, 1937. Newspapers across the country took note of his death. Secretary of the Treasury Henry Morgenthau Jr. stated that Mellon had lived through "an epoch in the economic history of the nation, and his passing takes one of the most important industrial and financial figures of our time". Mellon was buried at Trinity Episcopal Church Cemetery, Upperville, Virginia. Months after Mellon's death, the Board of Tax Appeals handed down a ruling exonerating Mellon of all tax fraud charges.
