"Oscar Niemeyer, the master Brazilian architect, hates airplanes. "Flying is crap," he says, succinctly. He loathes flying so much that he has stood up presidents, media grandees and tycoons. Fidel Castro once joked about sending a ship to fetch him. It's a wonder Brasilia, the city he conjured from red clay in the middle of the Brazilian nowhere, ever got built. But if his fear of flying has been one of Brazil's longest-standing jokes, Niemeyer has always had the last laugh: after all, he has built a career out of mocking gravity with concrete, stone and glass. At his best, he has made buildings soar, sculpting vertiginous whorls, waves, pods and chalices. Today, at 94, Niemeyer hasn't changed. When a grand retrospective of his work opened last month at the Galerie Jeu de Paume in Paris, Niemeyer remained where he always does: at home in Rio.
That's just where Brazil likes him. Half a century after unveiling his boldest work--the city of Brasilia--he is still the obligatory reference for building design in Brazil. Architecture has long been a notoriously gray-headed vocation--Philip Johnson is still building and Frank Lloyd Wright was at his drawing table almost until he dropped, at 96--and Niemeyer is going stronger than ever. Sketches and scale models for half a dozen projects, from Rio to Ravello, Italy, clutter the tables and walls in his studio, a spare penthouse overlooking Copacabana. Long known as Brazil's "official architect" ,he enchants students and established designers alike, casting a long shadow over the country's sprawling landscape. In fact, the Institute of Brazilian Architects recently asked its 100,000 members to select the architect of the century. Guess who won?"
