Augustus Owsley Stanley I was an American politician from Kentucky. A member of the Democratic Party, he served as the 38th governor of Kentucky and also represented the state in both the U.S. House of Representatives and the U.S. Senate. From 1903 to 1915, Stanley represented Kentucky's 2nd congressional district in the House of Representatives, where he gained a reputation as a progressive reformer. Beginning in 1904, he called for an antitrust investigation of the American Tobacco Company, claiming they were a monopsony that drove down prices for the tobacco farmers of his district. As a result of his investigation, the Supreme Court of the United States ordered the breakup of the American Tobacco Company in 1911. Stanley also chaired a committee that conducted an antitrust investigation of U.S. Steel, which brought him national acclaim. Many of his ideas were incorporated into the Clayton Antitrust Act.
