Peter Arrell Browne Widener (November 13, 1834 – November 6, 1915) was an American businessman, art collector, and patriarch of the wealthy Widener family. He began his career as a butcher, ran a successful chain of meat stores, and won a lucrative contract to supply mutton to Union army troops during the American Civil War. He partnered with William Lukens Elkins and William H. Kemble to found the Philadelphia Traction Company and established electric trolley systems in several major cities in the United States.
He was one of the founding organizers of American Tobacco Company, International Mercantile Marine Company, and U.S. Steel, and held significant investments in railroads, oil, and natural gas. He assembled a vast art collection valued between $15 and $50 million that he displayed at his Lynnewood Hall estate. Widener is on the American Heritage list of the forty richest Americans in history.
