Oscar Ribeiro de Almeida Niemeyer Soares Filho, known as Oscar Niemeyer, was a Brazilian architect considered to be one of the key figures in the development of modern architecture. Niemeyer was best known for his design of civic buildings for Brasília, a planned city that became Brazil's capital in 1960, as well as his collaboration with other architects on the headquarters of the United Nations in New York. His exploration of the aesthetic possibilities of reinforced concrete was highly influential in the late 20th and early 21st centuries.

Brasília is the federal capital of Brazil and seat of government of the Federal District. The city is located in the Brazilian highlands in the country's Central-West region. It was founded by President Juscelino Kubitschek on 21 April 1960, to serve as the new national capital. Brasília is estimated to be Brazil's third-most populous city after São Paulo and Rio de Janeiro. Among major Latin American cities, it has the highest GDP per capita.
