Acclaimed sociologist Elijah Anderson has been called "one of our best urban ethnographers" by the New York Times Book Review. Anderson is currently the William K. Lanman, Jr. Professor of Sociology at Yale University and the Charles and William L. Day Distinguished Professor Emeritus at the University of Pennsylvania. He is the author of Code of the Street and Streetwise, two compelling books about life in America's inner-cities based on research completed in Philadelphia. In The Cosmopolitan Canopy, Philadelphia is the setting for Anderson's investigation of the complex interplay of urban social nexuses—like Rittenhouse Square, Reading Terminal Market, and 30^th Street Station—that he dubs “cosmopolitan canopies.”
