The history of Imperial College London can be traced back to the founding of the Royal College of Chemistry in 1845 in London, with some ancestral medical schools dating back to 1823. The college was formed in 1907 out of the royal colleges in South Kensington, and throughout the 20th century became central to the national strategy for technical education and research.[1][2] It existed for most of its life as part of the University of London, only becoming independent in 2007.[3]
