A biographical anthology of Chicago’s most successful entrepreneurial families and the impact they had on American business. The book excels at telling each patriarch’s founding story, how Chicago’s position as a transportation and logistics hub provided a tailwind, and how subsequent generations expanded those early successes into enduring empires. Families profiled include Cyrus Hall McCormick (McCormick Harvesting Machine Company / International Harvester), Philip D. Armour (Armour & Company), Marshall Field (Marshall Field & Company), the Pritzker family (including Jay Pritzker and the founding of Hyatt Hotels), John D. MacArthur (Bankers Life and Casualty), William Wrigley Jr. (Wrigley Company), Arthur C. Nielsen Sr. (A.C. Nielsen Company), Gustavus Franklin Swift (Swift & Company), and John H. Johnson (Ebony and Jet magazines).
