Business history deals with the history of business organizations, methods, government regulation, labor relations, and impact on society. It also includes biographies of individual companies, executives, and entrepreneurs. It is related to economic history.
Even before academic studies began, Americans were enthralled by the Robber baron debate. As the United States industrialized very rapidly after the Civil War, a few hundred prominent men made large fortunes by building and controlling major industries, such as railroads, shipping, steel, mining and banking. Yet the newer who gathered the most attention was railroader Cornelius Vanderbilt. Historian Stephen Frazier argues that probably most Americans admired Vanderbilt; they agreed with biographer William Augustus Croffut who wrote in 1886:
However, Fraser goes on, there was a minority who vehemently dissented:
By the Great Depression of the 1930s, Fraser continues:
However a counterattack by academic historians began as the Depression ended. Business historian Allan Nevins challenged this view of big businessmen by advocating the "Industrial Statesman" thesis. Nevins, in his John D. Rockefeller: The Heroic Age of American Enterprise (2 vols., 1940), took on Josephson. He argued that while Rockefeller may have engaged in some unethical and illegal business practices, this should not overshadow his bringing order to industrial chaos of the day. Gilded Age capitalists, according to Nevins, sought to impose order and stability on competitive business, and that their work made the United States the foremost economy by the 20th century. Business journalist Ferdinand Lundberg later criticized Nevins for confusing readers. By contrast, historian Priscilla Roberts argues that Nevins' studies of inventors and businessmen brought about a reassessment of American industrialization and its leaders. She writes:
Historians and biographers who followed Nevins' lead include Jean Strouse, Ron Chernow, David Nasaw, and T. J. Stiles, chronicling the lives and careers of such dominant figures as J. Pierpont Morgan, John D. Rockefeller, Andrew Carnegie, and Cornelius Vanderbilt. Though these later biographers did not confer heroic status on their subjects, they used historical and biographical investigations to establish a more complex understanding of the American past, and the history of American economic development in particular.
