The first semi-permanent images were obtained in 1824 by Nicphore Niepce, a French physicist, using glass plates coated with a dispersion of silver salts in bitumen (a coal derivative). In the early 1830€™s, Niepce's partner, Louis Daguerre, discovered by accident that mercury vapor was capable of developing an image on a silver-plated copper sheet that had been previously sensitized BIA - Division of Energy and Mineral Resources Management 55 Indian Mineral Development Act (25 U.S.C. 2101-2108) • • Tribes may enter into any joint venture, operating, production sharing, service, managerial, lease or other agreement. • Agreements may be
