Sept 11 The Designer

In this April 7, 2011 photo, Michael Arad, an architect of the 9/11 memorial at ground zero, walks through the construction site in New York. Arad first imagined the twin reflecting pools with cascading waterfalls � he calls them voids � as two empty spaces in the Hudson River west of the smoldering World Trade Center, to mirror the absent towers. The pools moved to the twin towers' footprints, and the Israeli-born architect 's poster board sketch became the centerpiece for the world's most expensive memorial � and a touchstone for post-Sept. 11 battles over how to mourn and how to remember.
