Andrew W. Mellon by Melchers, Gari

This is Gari Melchers’ 1930 portrait of Andrew W. Mellon, now hanging in the National Gallery of Art in Washington, D.C. The painting itself is restrained, a dark suit, a muted brown wall, a hand resting on a chair, but the man in it changed American art forever.

Mellon was Secretary of the Treasury under three presidents, yet his most enduring act came after public office. He offered to build a national art museum, fill it with his own collection, and donate the whole thing to the country. Congress accepted in 1937, the year he died.

Look at the portrait: the crisp white moustache, the blue tie that breaks the monochrome, the hand on the armrest. Melchers gives him composure but no crown. The signature and date sit plainly at lower left, 1930, the moment this unlikely patron was quietly assembling a nation’s old masters with his own checkbook.

Raphael’s Alba Madonna cost him $1.1 million alone. This portrait? It stayed with the family until the museum acquired it decades later. The man who gave America its pictures ended up as one himself.
