New York is agog anew over modernist architect Ludwig Mies van der Rohe, at these two concurrent exhibits.

“Mies in Berlin,” at the Museum of Modern Art, examines the German native’s early work in Europe prior to his U.S. emigration in 1938. Fifteen models, 288 drawings, video, and photography make the case for Mies’ traditional roots. Through September 11. (212) 708-9400, www.moma.org

The designer left the European avant-garde for the American Midwest, where he encountered steel mills and advanced technology. The synthesis of lyrical design and pragmatic materials forms “Mies in America” at the Whitney Museum of American Art. Through September 23. (212) 570-3600, www.whitney.org
