Nathaniel P. Hill - Boston and Colorado Smelter

Most photos of Nathaniel P. Hill show the mature businessman, distinguished-looking U.S. Senator and publisher of the Denver Republican Newspaper. But it was the thirty-two-year old Hill who pioneered smelting methods and saved Colorado's fledgling mining industry.

A professor of chemistry at Brown University in Providence, Rhode Island, young Hill was already a rising star in scientific and business circles when he was contacted by mining men and investors in the Colorado territory to solve a problem with ores.

Gold had been discovered in Colorado in the fall of 1858, and fortune seekers rushed to the territory the following spring, finding "free gold" - nuggets and flakes - in their sluice boxes. But most of Colorado's valuable minerals were not "free" but bound up in complex ores. Without a method to economically separate minerals from the sulfides and bromides that trapped them, mining was fruitless. By 1864, the territory faced a crisis as prospectors and investors withdrew their money, mines closed, camps were deserted and settlements evaporated.

Hill arrived in Central City in 1864, intrigued by the challenge, but also attracted to the West as the place to make a name for himself. Hill observed first hand the problems of separating gold and silver from complex sulfide ores and methodically investigated various European smelting technologies, settling on a process developed in Swansea, Wales. With four other investors, Hill organized the Boston and Colorado Smelting Company in Black Hawk and by 1868 the smelter was in operation. 

For ten years, the Boston and Colorado was the only smelting operation in the Rockies to attain both technical and financial success, with production growing from $271,000 in 1868 to $2,260,000 in 1878. By 1878, the company needed to expand and relocated to an area of high ground between west 44th and 48th Avenues and Delaware to Fox Streets, taking advantage of the nearby Colorado Central and Denver Pacific Railroads. The Boston and Colorado built a company town known as Argo, and many people referred to the smelter as the Argo Smelter. (in Greek mythology, Argo is the name of a ship whose captain, Jason, hopes to find the golden fleece and claim his inheritance). The success of the plant prompted the construction of two smelters nearby: the Omaha and Grant in 1882 and the Globe Smelter in 1889.

Hill’s achievements led to a political career: he was elected mayor of Black Hawk in 1871, then Colorado‘s Republican Senator from 1879 to 1885, serving on the Committee on Mines and Mining and advocating for free coinage of silver. After his term ended, Hill purchased the Denver Republican newspaper to promote Republican causes. 

Hill's business success is well known, but his relations with his employees differed from that of his competitors. During the national recession of 1893, both the Grant and Globe Smelters closed, laid of workers and waited for economic conditions to improve. When those plants reopened, new hires were forced to take a 10 to 15 percent reduction in pay, leading to resentment, unrest and strikes. During the same period, Hill reduced his own salary, but not that of his employees saying that he could stand the loss better than they could.* (Because the Boston and Colorado processed ores containing gold, the plant was able to operate without layoffs). Hill's employees never joined the Mill and Smeltermen's Union.

Hill died in Denver on May 22, 1900 and is buried at Fairmount Cemetery.
