It takes a very special exhibition to be so grand that it sprawls across not one but two nationally renowned museums. But that is exactly what architect and design artist Eero Saarinen's work required when "Shaping the Future" visited the Twin Cities last year. Perhaps most famous for the St. Louis Gateway Arch, Saarinen, during his prolific yet short career (he lived to be only 51), created innovative designs whose influence can be seen in many buildings and structures today. The Walker's portion of the retrospective included his sleek, modern furnishings, as well as designs for churches and corporate spaces. The MIA focused on his early work, as well as his designs for airports, memorials, and embassies.
