Vlado Milunić, a Czech architect of Croatian ancestry who co-designed Prague’s iconic Dancing House building together with colleague Frank Gehry, has died at 81.

Even after two decades, the work to rebuild the World Trade Center complex after its destruction in the Sept. 11 attacks is still incomplete.

Eli Broad, the billionaire philanthropist, contemporary art collector and entrepreneur who co-founded homebuilding pioneer Kaufman and Broad Inc. and launched financial services giant SunAmerica Inc., died Friday in Los Angeles.

Paul Williams was a trailblazing architect whose long career helped shape Los Angeles and Southern California. The Los Angeles County Courthouse, Los Angeles International Airport and First African Methodist Church were among the projects he led or worked on. He was the first African American member of the American Institute of Architects, its first African American Fellow and the first African American recipient of the institute's Gold Medal, its highest honor. Born in Los Angeles in 1894, Williams was orphaned following the death of his father at age 2 and his mother at age 4.
