Knight House, the Knight–Mangum House, and the Thomas N. Taylor House. All of these homes derive from the high style: Eastlake, Shingle, Craftsman, Italianate, Classical, Moorish, Colonial, and Romanesque Revivals. Made primarily of brick, these homes exhibit the finest architecture and most ornate detailing to be found in the city of Provo. Jesse Knight and the Tintic mining industry The successful commercial mining of precious metals and minerals transformed Utah's economy from basically an agrarian base to a more industrialized state. Within this development the Tintic Mining District, located approximately thirty miles southwest of Provo, was founded in 1869 and by 1899 became the leading mining center in Utah with a value of output placed at $5 million. A central figure in Tintic success was Jesse Knight and the Knight family who resided in Provo. Jesse Knight attained wealth with his Humbug mine in the mid-1890s. The large silver producer allowed Knight to develop other mines in the East Tintic area. Knightsville grew around the workings and became touted as the only saloon-free, prostitute-free, privately owned mining camp in the U.S. His strict adherence to doctrines of The Church of Jesus Christ of Latter-day Saints made the town one inhabited primarily by members of that church. Jesse Knight was able to expand farther than the tintic mines, reaching to the power plant in Santaquin, the Tintic drain tunnel project, the Knight Dry farm, and the smelters at Silver City. The Bonneville Mining company, the Knight Woolen Mills, Ellison Ranching Company, The American-Columbian Corporation, The Springville–Mapleton Sugar Company, The Spring Canyon Coal Company, Utah Savings Bank, The Layton Sugar Company, and the Tintic Drain Tunnel Company all represent facets of the Knight Investment Company. W. Lester and Jennie Knight Mangum W. Lester Mangum was born in 1873 in Nephi, Utah. He attended Brigham Young University and was made an instructor in English there. In 1905 he married Jennie Knight, the daughter of the mining magnate Jesse Knight. Mangum was quickly included in the Knight family businesses and held different executive positions in these businesses. He also served as vice-president and manager of the American Colombian Corporation which owned huge tracts of land in South America. Mangum was active in The Church of Jesus Christ of Latter-day Saints, and served as a member of his stake's high council. Mrs. Mangum was active in civic and church affairs.
