Ida Tarbell (1857 – 1944) was a muckracker, which is a term used to describe a generation of journalists that, during the Progressive Era (end of the 19th century and first years of the 20th century), condemned corrupt practices in the US governmental offices and businesses in their publications.

In 1904, her book " The History of the Standard Oil Company" was published, which was actually a recopilation of articles that had been progressively published in McClure's Magazine between 1902 and 1904.
