The personal papers of Charles Lang Freer (1854–1919), an industrialist and art collector who founded the Freer Gallery of Art, form the nucleus of the Galleries’ Archives. They document the pioneering efforts that built one of the great American collections of Asian art and the largest collection of works by American artist James McNeill Whistler (1834–1903) now in a public museum. Papers include Freer’s correspondence with public figures, scholars, dealers, and collectors such as Bunkio Matsuki, Ernest Fenollosa, and Dikran Kelekian, and with artists such as Whistler, Thomas Wilmer Dewing, and Dwight William Tryon. Also included are vouchers documenting Freer’s purchases, inventories of his art collection, scrapbooks containing newspaper clippings, travel notes, and diaries. Various Whistleriana, along with Freer’s correspondence with Whistler, provides scholars with one of the largest sources of primary documentation about the artist, second only to the holdings of the University of Glasgow’s Centre for Whistler Studies. Photographs in the papers document Freer’s life, friends and associates, and his travels between 1895 and 1911, primarily to China, Egypt, Italy, and Japan. There are also photographs that Freer acquired during his travels, including a noteworthy group of images of Sri Lanka. Together, these papers form a major resource for ongoing studies of Asian art patronage in the late nineteenth– and early twentieth–century United States.
