Part 2 (of three) of “Chicago: City of the Century” covers the 1870s and ’80s, when the city’s can-do business leaders found themselves increasingly at odds with labor. The episode profiles meatpacker Augustus Swift; sleeping-car magnate George Pullman, who established what he hoped would become a utopian workers community; and merchant prince Marshall Field, who had no such notions. Then there were the anarchists. Based on the book by historian Donald L. Miller.
