“The World's Foremost College of Mineral Engineering,” as this school calls itself, started in 1869 as an Episcopal school, St. John's in the Wilderness. Five years later Colorado Territory adopted the foundling institution, which is still a state school. Three early Second Empire mansard-roofed brick buildings have disappeared, although Jarvis Hall (1878, Duncan E. Harrison, builder) survives off campus as a private apartment house at 921 19th Street. Notwithstanding an 1894 master plan by Robert S. Roeschlaub and a 1950 plan by Fuller, Fuller and Fuller, campus architecture is discordant, offering decade-by-decade examples of the latest institutional styles, ranging from the Romanesque Revival favored by the Roeschlaub plan to stark solar. Much work here has been done by Fuller, Fuller and Fuller, a Denver firm comprising three generations of the same family. As the descendant of the old Roeschlaub and Fuller firm, it is the state's oldest architecture firm. Besides developing the 1950 master plan, which called for Modernist buildings, the Fullers designed Alderson Chemical and Petroleum Engineering Hall (1953), Coolbaugh Chemistry Hall (1952), Nathaniel Hill Metallurgy Hall (1958), Paul Meyer Physics Hall (1963), and Volk Gymnasium (1957). Other notable construction includes the Steinhauer Field House (1937, Jacques Benedict), George R. Brown Geology Hall (1979, Lamar Kelsey), Green Center (1970, Kenneth R. White), and a five-story Modernist, solar dormitory (1979, John D. Anderson). Since 1985 many campus buildings have been restored on the exterior and renovated inside.
