Le Corbusier was a Swiss-born French architect who belonged to the first generation of the so-called International school of architecture. Le Corbusier was born Charles-Edouard Jeanneret-Gris in Switzerland on October 6, 1887. In 1917, he moved to Paris and assumed the pseudonym Le Corbusier. In his architecture, he chiefly built with steel and reinforced concrete and worked with elemental geometric forms. Le Corbusier’s painting emphasised clear forms and structures, which corresponded to his architecture. After designing his first house, in 1907, at age 20, Le Corbusier took trips through central Europe and the Mediterranean, including Italy, Vienna, Munich and Paris.
