Oscar Niemeyer (born December 15, 1907) is a Brazilian architect who is considered one of the most important names in international modern architecture.
He was a pioneer in the exploration of the constructive possibilities of reinforced concrete.
His buildings are often characterised by being spacious and exposed, mixing volumes and empty space to create unconventional patterns and often propped up by pilotis. Both lauded and criticised for being a "sculptor of monuments", his most famous design, the plan for the city of Brasilia, is a UNESCO World Heritage Site.
