To his 100th anniversary, over seven decades since one of his first projects - a 1936 collaboration with Lucio Costa and Le Corbusier - Oscar Niemeyer is still practicing. A technical pioneer and one of the 20th century's most important architects, Niemeyer has designed close to 700 realized and unrealized buildings and, most notably, was the architect for the principal monuments in Brasilia, his homeland's futuristic capital city and his undisputed major masterpiece.
