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 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. The architects Walter E. Ware and Alberto O. Treganza either separately or together were engaged in the construction of the Jesse Knight House. Preservation The house was listed on the National Register of Historic Places in 1982 as part of a multiple property submission that nominated seven and listed six Provo houses. The listed houses are the Knight-Mangum House, the John R. Twelves House, this, the Jesse Knight House, the Knight-Allen House, the William H. Ray House, and the Thomas N. Taylor House. The seventh, the Charles E. Loose House, was determined to be NRHP-eligible but was not NRHP-listed due to owner objection.
