Le Corbusier (1887-1965) was a Swiss-born architect, painter and urban planner. He is generally considered as one of the main forces in the development of modernist architecture. UNESCO has designated 17 of his building projects as “world heritage sites,” more than any other architect. In the 1940s Le Corbusier developed a system of measurements called the Modulor to assist in the fitting buildings to human beings. The first building to be constructed using the Modulor was the Unité d’Habitation, a striking and innovative residential building in Marseille, begun in 1947 and completed in 1952. In recent years, Le Corbusier has been criticized for his antisemitism and his fascist leanings. These critiques do not detract from the importance of his work but do explain how his buildings sometimes seem inhuman.
