A Swiss-French architect born in 1887, Charles Édouard Jeanneret made some of the most significant contributions to architecture in the 20th century. He and the painter Amédée Ozenfant began the publication "L'Esprit Nouveau" in 1920 and wrote under pseudonyms. Jeanneret chose a name from his family lineage: Le Corbusier. Le Corbusier embraced functionalism, rejecting excessive nonstructural ornamentation, and favored the modern materials of concrete and steel in his structures. He was particularly well-known for his houses and would become a major figure in the developing the International Style of architecture. His designs used free-flowing floor plans, as well as column support that allowed for walls that could be placed independent of the structure. He placed his buildings on stilts, partly because he believed this to be conducive to a hygienic lifestyle. And finally, his buildings incorporated flat roofs that could accommodate gardens. Summing up his philosophy, he described a house as "a machine for living in."
