194X–9/11: American Architects and the City, now at the Museum of Modern Art in New York, takes its name from a 1943 issue of Architectural Forum. The magazine commissioned designs from 23 architects for an imagined postwar American city to begin when World War II was over—or in “194X.” The exhibit highlights those designs, as well as post-1945 plans (including Ludwig Mies van der Rohe’s plan for Chicago and Louis Kahn’s plan for Philadelphia), Leon Krier’s pedestrian-friendly national capital, and the proposed designs for the World Trade Center site (THINK Design’s proposal is shown above), which together consider the effects that more than a half-century of cyclical global conflict and economic woe have had on America’s urban landscape since the end of World War II.
