IDA TARBELL (1857–1944) is best known for her work “The History of the Standard Oil Company,” which appeared as a nineteen-part series in McClure’s Magazine between November 1902 and October 1904. Tarbell once remarked on why she dedicated years of her life to investigating the company: “They had never played fair, and that ruined their greatness for me.” For muckrakers and investigative journalists like Tarbell, exposing such corruption was a driving force behind their work.
