In 2012 the Avery Library at Columbia University bought from the Wright Foundation the huge archive that the architect put together in the course of his career of almost seventy years: 55,000 drawings, 125,000 photographs, 300,000 letters, and innumerable telegrams and videos. To celebrate this important acquisition and coinciding with the 150th anniversary of Wright’s birth, Barry Bergdoll invited a group of scholars to dig into the archives, selecting themes that have not been much addressed in order to come up with a different picture of the master from Wisconsin. The result is ‘Frank Lloyd Wright at 150: Unpacking the Archive,’ a major show on view in the New York MoMA’s renovated galleries until 1 October.
