Henry Clay Frick was an American industrialist, financier, and art patron. He founded the H. C. Frick & Company coke manufacturing company, and later became chairman of the Carnegie Steel Company. Frick's management of Carnegie Steel was characterized by vehement opposition to unions, a trait reflected most notably by his violent suppression of the Homestead Strike. In the later years of his career as an industrialist, he was instrumental in the founding of U.S. Steel, which became the world's largest steel manufacturer.
