Le Corbusier, born Charles-Edouard Jeanneret-Gris in 1887 in La Chaux-de-Fonds, Switzerland, studied painting and architecture at the local Ecole d'Art. In 1907, he worked for Josef Hoffmann in Vienna, where he also made the acquaintance of Adolf Loos. Another important influence came when he was working in Paris in 1909 for over a year in the practice of Auguste Perret, a pioneering exponent of building with reinforced steel. During this period, he also visited the architect and urban planner Tony Garnier in Lyon.  

It was not long before Le Corbusier was focusing on modern reinforced concrete architecture. 

In 1917, he moved to Paris. SInce he only  had a few architectural commissions at the time, he spent much of his time painting, producing mainly still life's. In 1919, Le Corbusier joined the painter Amedee Ozenfant and the poet Paul Dermee to found the journal "L'Esprit Nouveau.", in which he began first using his pseudonym in 1920. 

In 1922, Le Corbusier produced an urban planning concept for a Ville Contemporaine - a "contemporary city with a population of three million." In 1925, he collaborated with his cousin Pierre Jeanneret on designing a two-storied pavillion for the Exposition Internationale des Arts Decoratifs in Paris. The avant-garde architecture of that pavilion was complemented by furnishings of functional design and paintings by Le Corbusier, Ozenfant, Fernand Leger, Jacques Lipchitz and others. 

By 1927, Le Corbusier was among the leading practitioners of the New Architecture designing the housing for the WeiBenhof Settlement in Stuggart. From 1927, he collaborated with Pierre Jeanneret and Charlotte Perriand to produce designs for functional furniture - including the LC4 chaise lounge - which they showed at the 1929 Paris Salon d'Automme. Around 1942, he formulated his "Modular" theory, which was Le Corbusier's term for a system of proportion based on the Golden Mean that he used in his architectural designs, especially in his large-scale urban planning projects. Intended to facilitate architecture on a human scale based on an objective system, the Modular still remains one of the most controversial of Le Corbusier's theoretical approaches to architecture. 

Le Corbusier also made substantial contributions to architecture theory as a co-founder of the Congres Internationale Moderne (CIAM), which first convened in 1928. In 1952, the first Unite d'Habitation was finished in Marseilles, followed by further modular residential units in other locations. Le Corbusier designed the pilgrimage chapel of Notre-Dame-du-Haut at Ronchamps in 1955.

Le Corbusier died in 1965 in Roquebrune-Cap-Martin.
