Prof. Dominic A. Pacyga is a historian and researcher who analyzes the city of Chicago not just as an urban conglomerate, but as the collective and diverse story of settlers, immigrants, and locals who built it through their flesh and turned it into the "most American city". Teaching for over four decades, at Columbia College and the University of Chicago, his book—published by the University of Chicago Press— and titled "Chicago: A Biography" is a vivid portrait of the quintessential skyscraper jungle. His work as an author appeals both academics and individuals, with the exploration of the "city of neighborhoods".
