Charles-Édouard Jeanneret-Gris, known as Le Corbusier, was a pioneering Swiss-French architect who developed new styles of modern architecture. Some of his key contributions included developing the Domino house system during World War I and emphasizing five points of architecture including pilotis, free facades, open floor plans, ribbon windows, and roof gardens. Le Corbusier designed several major projects including the UN headquarters in New York and the city of Chandigarh in India. One of his most famous designs was the Unité d'Habitation apartment building in Marseilles, which attempted to realize his urban planning vision on a small scale.
