AMHERST, Mass. - Long before the events of Sept. 11, Max Page was thinking about the destruction of New York City. Page, new assistant professor of art and adjunct assistant professor of history at the University of Massachusetts, is the author of The Creative Destruction of Manhattan, 1900-1940: (University of Chicago Press, December 1999). The book offers an explanation of how and why New York City became a place of continuous rebuilding and explores the connections among its social, cultural, and urban histories. It has been two years since the book was published, but the events of Sept. 11 have brought its subject matter into the limelight.
