Standard Oil

John D. Rockefeller and Standard Oil: the first great American monopoly. From a Cleveland bookkeeper to controlling 90% of US oil refining. The story that defined antitrust law, corporate ruthlessness, and modern philanthropy.

Canon

Rockefeller didn't view cost-cutting as a business tactic but as a moral obligation. Waste was sinful. This stoic control of what was within his power (efficiency, process, discipline) created an unbeatable cost structure.
Rockefeller was a voracious reader and bookkeeper who studied business principles systematically before building Standard Oil. His mentors were ledger books and business histories, not living advisors.
