You may have seen or even had the pleasure of visiting Eero Saarinen's most famous works without realizing it. For starters, the Gateway Arch, in St. Louis, Miss., and the TWA terminal in New York's JFK Aiport are some of the Finnish American's most noted sites. But he's also churned out other pieces that have been just as influential in industrial design, such his Tulip collection, a series of neofuturstic chairs and tables, which also made a cameo in Stanley Kubrick’s film "2001: A Space Odyssey."
