Gillespie, the author of a book on the World Trade Center published in 1999, will speak at 1:30 p.m. Thursday, Oct. 18, in Guyot 10.
His talk, "Twin Towers: The Life and Death of the World Trade Center," is sponsored by the Princeton Environmental Institute .
Gillespie, professor of American studies at Rutgers University, began researching his book, "Twin Towers: The Life of New York City's World Trade Center," in 1991. He wanted to explore the complex's cultural implications and symbolic meaning to Americans.
Before Sept. 11, only about 2,000 copies of the book had been sold by Rutgers University Press. Bookstores have now ordered more than 50,000 copies. Gillespie and the publisher are donating a portion of the profits to victims of the World Trade Center attacks.
