Charles-Édouard Jeanneret, better known as Le Corbusier was a Swiss architect, designer, urbanist, writer and painter, famous for being one of the pioneers of what now is called modern architecture. He was born in Switzerland and became a French citizen in 1930. His career spanned five decades, with his buildings constructed throughout central Europe, India, Russia, one in North and several in South America.
He was a pioneer in studies of modern high design and was dedicated to providing better living conditions for the residents of crowded cities.
Le Corbusier adopted his pseudonym in the 1920s, allegedly deriving it in part from the name of a distant ancestor, "Lecorbésier." However, it appears to have been an earlier (and somewhat unkind) nickname, which he simply decided to keep.
