The Royal School of Mines was established in 1851, as the Government School of Mines and Science Applied to the Arts. The School developed from the Museum of Economic Geology, a collection of minerals, maps and mining equipment made by Sir Henry De la Beche, and opened in 1841. The museum also provided some student places for the study of mineralogy and metallurgy. Sir Henry was the director of the Geological Survey of Great Britain, and when the collections outgrew the premises the museum and the survey were placed on an official footing, with government assistance. The Museum of Practical Geology and the Government School of Mines and Science Applied to the Arts opened in a purpose-designed building in Jermyn Street in 1851. The officers of the Geological Survey became the lecturers and professors of the School of Mines. The Royal College of Chemistry was merged into it in 1853. The name was changed in 1863 to the Royal School of Mines, and was moved to South Kensington in 1872. In 1907, the school was incorporated into Imperial College of Science and Technology, but retained its own identity as a "constituent college". In 2001 Imperial moved from a constituent college structure to a faculty structure, a move that was completed in 2003.
