Toward the end of the Great Depression, Ward Melville, his wife Dorothy Melville, Robert Cushman Murphy, Winifred Curtis and O.C. Lempfert created the Suffolk Museum on the very site that now houses The Jazz Loft. As their collections grew it was moved to its current location. The Long Island Museum of American Art, History, and Carriages, informally known as the Long Island Museum, is known for its collection of over 200 carriages and its extensive array of work by famed painter William Sidney Mount and over 4000 other paintings, sculptures and prints. The museum has been accredited by the American Association of Museums since 1973 for excellence in exhibitions, programs and collection care. In 2006 the museum joined a small group of institutions nationwide as a Smithsonian Affiliate.
