Charles Holden (1875–1960) was an English architect best known for designing many London Underground stations during the 1920s and 1930s, for Bristol Central Library, the Underground Electric Railways Company of London's headquarters at 55 Broadway and for the University of London's Senate House. He also created many war cemeteries in Belgium and northern France for the Imperial War Graves Commission. Although not without its critics, his architecture is widely appreciated. He was awarded the Royal Institute of British Architects' Royal Gold Medal for architecture in 1936 and was appointed a Royal Designer for Industry in 1943. His station designs for London Underground became the corporation's standard design influencing designs by all architects working for the organisation in the 1930s. Many of his buildings have been granted listed building status, protecting them from unapproved alteration. Modestly believing that architecture was a collaborative effort, he twice declined the offer of a knighthood.
