Need one ask? Ludwig Mies van der Rohe (originally just Ludwig Mies until he added his mother's maiden name by means of the pseudo-aristocratic "van der") was director of the hard-left Bauhaus design school in Dessau when the new Nazi -dominated town council closed it down in 1932. Mies had designed a monument to Communist martyrs that the Fascists demolished. He had wealthy Jewish clients. His cool avant-garde style, all historic references by then expunged, was at odds with the preferred triumphalist architecture of the Third Reich. He lost most of his work as a result of the Nazis. And yet, he waited until 1938 to get out and start a new career in America. And the stunningly good new Mies exhibition at the Whitechapel Art Gallery shows two projects that make you stop and think, hmmm - a slight tweak in the space-time continuum, and Mies could have been another Albert Speer.
