Brazilian architect Oscar Niemeyer’s condition has worsened, doctors treating the 104-year-old designer of Brazil’s modernist capital said Monday. His doctor said he had been transferred to a coronary unit but was “lucid and continues undergoing respiratory physiotherapy.” The architect, winner of the 1988 Pritzker Prize, is best known as one of the principal designers of Brasilia, the futuristic capital built in 1960. A pioneer in the use of reinforced concrete to produce soaring, curvaceous forms, he has designed 600 works around the world and has some 20 other projects underway. He was hospitalized Nov. 2 suffering from dehydration after coming down with the flu, the latest in a series of lengthening hospital stays. His only daughter, Anna Maria Niemeyer, died of emphysema in June at age 82.
