All that remains of Alexander Calder’s Bent Propeller are four pieces of melted steel, one of which is on display in the 9/11 Memorial Museum. The 25-foot-tall sculpture was originally procured by the Port Authority in 1971 to help “humanize” the vast, empty plaza surrounding the recently completed Twin Towers. Silverstein would later convince the Port Authority to loan it to him. “It was originally commissioned for the entrance to One World Trade Center on West Street, but I convinced the Port that the elevated plaza in front of Seven World Trade Center would be a much better location,” he recalls.
