Charles-Edouard Jeanneret, known as Le Corbusier, was born at La Chaux-de-Fonds, in the Swiss Jura, in 1887; he died in France, at Cap Martin, on the French Côte d’Azur, in 1965. Early in his career his work met with some resistance owing to its alleged «revolutionary» nature and the radical look it acquired from its «purist» experiments; in time , however, it won the recognition it deserved and it is still widely admired. His message is still being assimilated by an ever increasing number of people in the profession, but his far-out avant-garde attitudes should be interpreted with due consideration for the use of rational systems in his planning method, evidenced by extremely simple modules and formes based on the functional logic.
