Spencer Penrose (November 2, 1865 – December 7, 1939) was an American entrepreneur and philanthropist. He made his fortune from mining, ore processing, and real estate speculation in Colorado and other parts of the West. He founded the Utah Copper Company in 1903, and also established mining operations in Arizona, New Mexico and Nevada.
He settled with his fortune in Colorado Springs, Colorado, where he and partner Charles L. Tutt had a road constructed to the top of Pikes Peak. They initiated an annual motor car race to the top. In 1918 Penrose opened an opulent resort hotel known as The Broadmoor, built outside the city which was a "dry" community. In 1937 he and his wife Julie established the El Pomar Foundation, to support activities to improve Colorado. In 2001, Penrose was inducted into the Hall of Great Westerners of the National Cowboy & Western Heritage Museum.[1]
