Named after Peter B. Lewis, chief executive and president of Progressive Insurance, Gehry's building in the Case Western Reserve campus is a $62 million building (of which Mr. Lewis gave $37 million) with 152,000 square feet of space. Peter B. Lewis and Frank Gehry have had a long professional and personal career dating back to Lewis' commissioning Gehry to design his home, which was never built. The long design process for the unbuilt home is credited with having helped many of the design advances that would lead to Gehry's design of the Guggenheim Museum in Bilbao. Like in Bilbao, here Gehry makes use of the undulating forms that have now become his signature.  Photo 5 of 14 in 13 Iconic Buildings Designed by Frank Gehry
