KahnÕs use of materials
¥ ÒKahn used materials in a way that anticipated the effects of weather and age, and in this he departed radically from the Modernists.  The stains that rapidly appeared on the stucco of GropiusÕs Graduate Center at Harvard made it look shabby and cheap.  By contrast, the streaks on the concrete and the bleaching of the teakwood panels at Salk made the building appear durable and strong, recording years of salt spray and bright sunlight.  KahnÕs are clearly buildings with a past - and a future.Ó
