Architect Ludwig Mies van der Rohe immigrated to the US from Germany around 1938. In America, Mies van der Rohe’s career as an architect and teacher flourished, and his distinctive high-modernist designs proved hugely influential on generations of architects internationally. It wasn’t until his last project, the weightless pavilion for Berlin’s New National Gallery (pictured here in a perspective collage), completed in 1968, that Mies van der Rohe again set foot in the country of his birth.
