The Tycoons: How Carnegie and Rockefeller Built America
Charles R. Morris's book The Tycoons compares how Carnegie, Rockefeller, Gould, and Morgan each built the post-Civil War American economy. Carnegie cut costs and scaled steel, Rockefeller out-managed rivals in oil, Gould mastered railroad finance, and Morgan tried to impose order, together creating the infrastructure that let consumer brands like Procter & Gamble emerge.
