Hailed for his impressive work, Frank Gehry has single-handedly changed conventional ideas about architecture. As a modernist inspired by Alvar Aalto, he has always been concerned with how to "humanize" a building. His answer: through the inventive use of materials. Gehry's unique vision has brought him numerous honors, including the 1989 Pritzker Prize, the 1998 National Medal of Arts Award, the 2000 American Institute of Architects Gold Medal. Recent masterpieces include the Guggenheim Museum in Bilbao and The Disney Concert Hall in Los Angeles California.
