Andrew William Mellon (/ˈmɛlən/; March 24, 1855 – August 26, 1937), known also as A. W. Mellon, was an American banker, businessman, industrialist, philanthropist, art collector, and politician. The son of Mellon family patriarch Thomas Mellon, he established a vast business empire before moving into politics. He served as United States Secretary of the Treasury from March 9, 1921, to February 12, 1932, presiding over the boom years of the 1920s and the Wall Street crash of 1929. A conservative Republican, Mellon favored policies that reduced taxation and the national debt of the United States in the aftermath of World War I. Mellon also helped fund and manage Kennywood Park in West Mifflin, Pennsylvania.

Andrew began working at his father's Pittsburgh, Pennsylvania, bank, T. Mellon & Sons, in the early 1870s, eventually becoming the leading figure in the institution. He later renamed T. Mellon & Sons as Mellon National Bank and established another financial institution, the Union Trust Company in Pittsburgh in 1889. By the end of 1913, Mellon National Bank held more money in deposits than any other bank in Pittsburgh, and the second-largest bank in the region was controlled by Union Trust. In the course of his business career, Mellon owned or helped finance large companies including Alcoa, the New York Shipbuilding Corporation, Old Overholt whiskey, Standard Steel Car Company, Westinghouse Electric Corporation, Koppers, the Pittsburgh Coal Company, the Carborundum Company, Union Steel Company, the McClintic-Marshall Construction Company, Gulf Oil, and numerous others. He was also an influential donor to the Republican Party during the Gilded Age and the Progressive Era.

The Cheoah Dam is a hydroelectric dam located in Graham and Swain counties, North Carolina, on the Little Tennessee River between river miles 51 and 52. The Cheoah Development consists of a dam and powerhouse, the first of several constructed by the Tallassee Power Company (now Tapoco), a subsidiary of Aluminum Company of America (now Alcoa), in order to generate electricity to smelt aluminum in Alcoa, Tennessee. The name Cheoah comes from the Cherokee Native American word for "otter."

The Cheoah project began in 1916 as a construction camp at the Narrows, where the Little Tennessee River flowed through a narrow gorge, and it was completed in 1919. Cheoah Dam created the long, narrow Cheoah Reservoir, which covers approximately 644 acres (261 ha) of the normal full pool area and a drainage area of 1,608 square miles (4,160 km). The elevation of Cheoah Reservoir is 1,276.8 feet (389.2 m) (USGS). A scenic highway runs the length of the reservoir.
