World Trade Center Historian Reflects on 20th Anniversary of 9/11

Two decades before the Twin Towers fell on September 11, 2001 they soared above the New York City’s skyline. Today, the towers stand only in our memory, says Angus Gillespie, a professor of American Studies at Rutgers University-New Brunswick and author of “Twin Towers: The Life of New York City’s World Trade Center,” who will teach a course this fall honoring the nearly 3,000 Americans killed in the attack.
