Ida M. (Ida Minerva) Tarbell

Born in Pennsylvania's oil country in 1857, Ida Minerva Tarbell grew up close to the world she would later scrutinize so famously. She studied at Allegheny College and went on to build a career as a teacher, writer, lecturer, and journalist.

Tarbell is best known for her landmark investigation of Standard Oil, first published in McClure's Magazine and later collected as The History of the Standard Oil Company in 1904. The work made her one of the best-known "muckrakers" of her time and helped establish investigative reporting as a powerful force in American public life.

She also wrote biographies and historical works, bringing the same patient, readable style to subjects ranging from Abraham Lincoln to the world of American industry. Remembered as a pioneering journalist and a clear-eyed observer of power, she remains an important figure in the history of nonfiction writing.
