Architect Oscar Niemeyer, who recreated Brazil's sensuous curves in reinforced concrete and built the capital of Brasilia on the empty central plains as a symbol of the nation's future, died Wednesday. He was 104.

His hallmarks include much of the U.N. complex in New York.

He won the Gold Medal from the American Institute of Architecture in 1970 and the Pritzker Architecture Prize from Chicago's Hyatt Foundation in 1988.
