Wolfgang Staehle, 2001

On the morning of Sept 11, 2001, German artist Wolfgang Staehle was readying his video installation for Postmasters Gallery in Chelsea—a live wide-angled webcam feed of lower Manhattan from Williamsburg, Brooklyn, including a view of World Trade Center—when suddenly, his camera caught the attacks on the Twin Towers just as they happened. What had been intended as a "panorama of eventlessness" had been instantaneously transformed into a searing document of one of history's most terrible and transformative events. Ten years on, the Goethe-Institut's Lower East Side outpost hosts a reinstallation of the nine-hour-long 2001, unspooling in real time as it did a decade ago.
