Born in 1857, she grew up in Pennsylvania amidst the oil industry's boom, which later fueled her interest in journalistic integrity and corporate ethics.

Rockefeller, which highlighted issues of corporate greed and exploitation. Her work was characterized by thorough research and a commitment to factual accuracy, laying the groundwork for modern investigative journalism. Tarbell's seminal book, "The History of the Standard Oil Company," published in 1904, not only drew public attention to monopolistic practices but also encouraged reforms in corporate regulation. Her efforts were instrumental in the eventual breakup of Standard Oil and set a precedent for regulating large corporations to protect public interests.
