"The Millionaire Yield of Denver" by Isaac F. Marcosson This article examines Denver's rapid accumulation of wealth, featuring illustrated profiles of prominent Colorado millionaires including Horace Tabor (former stone-cutter enriched by Leadville mines), Edward Oliver Wolcott (lawyer and investor), and Thomas M. Patterson (proprietor of the Rocky Mountain News). Marcosson argues that Western millionaires, bred from native American stock and frontier enterprise, differ fundamentally from Eastern industrial magnates. He traces Denver's transformation from an 1858 prospecting camp on Cherry Creek through the 1870 railroad connection and the 1878 Leadville silver strike—which brought figures like James Campion and created the "era of established wealth." The narrative emphasizes mining, ranching, and railroad investments as wealth-sources, celebrating Denver's distinctive character as "the most typically American" of thriving cities.
