Charles Lang Freer (February 25, 1854 – September 25, 1919) was an American industrialist, art collector, and patron. He is known for his large collection of East Asian, American, and Middle Eastern Art. In 1906, Freer donated his extensive collection to the Smithsonian Institution, making him the first American to bequeath his private collection to the United States. To house the objects, including The Peacock Room by James McNeill Whistler, Freer funded the construction of the Freer Gallery of Art in Washington, D.C.
