Desmond Fitzgerald (1846-1926) was an art patron, art collector, and engineer based in Brookline, Massachusetts. He served on the boards of the Boston Public Library and the Copley Society. In 1913, Fitzgerald arranged to have the Armory Show come to Boston. His collection of mainly French and American impressionist paintings by Claude Monet, Dodge Macknight, and others became a kind of semi-public museum. Upon his death, the collection was sold at auction.
