Oscar Niemeyer (1907–2012) was a Brazilian architect renowned for his sensual, curvilinear forms and innovative use of concrete. A leading figure in modernism, he designed many of Brasília’s government buildings, including the National Congress of Brazil, as well as global landmarks like the United Nations Headquarters (with Le Corbusier) and the Museum of Contemporary Art in Niterói. His architecture blended sculptural elegance with structural audacity, often inspired by the fluidity of natural landscapes. Awarded the Pritzker Prize (1988), Niemeyer’s visionary work continues to inspire architects seeking to merge artistic expression with functional design.
