Ida Tarbell was an American teacher, author and journalist. She was one of the leading "muckrakers" of the progressive era. She wrote many notable magazine series and biographies and is best known for her 1904 book The History of the Standard Oil Company, which was listed as No. 5 by New York University of the top 100 works of 20th-century American journalism. She depicted John D. Rockefeller as crabbed, miserly, money-grabbing, and viciously effective at monopolizing the oil trade.
Ida Tarbell began her career as a journalist while doing graduate work in Paris, eventually becoming the editor of McClure's magazine. In 1900 she began researching Standard Oil, eventually exposing the unsavoury business practices and corruption on the pages of McClures, beginning the tradition of investigative journalism. She was referred to as a "muck raker", yet however much she disliked the term, it has stuck for journalists leaving no stone unturned for the truth (km).
