Andrew Carnegie (properly pronounced /kɑrˈneɪɡi/ (kar-NAY-gee), but commonly, /ˈkɑrnɨɡi/ or /kɑrˈnɛɡi/) (25 November 1835 – 11 August 1919) was a Scottish-American industrialist, businessman, entrepreneur and a major philanthropist. He was one of the most famous leaders of industry of the late 19th and early 20th centuries.
He earned most of his fortune in the steel industry. In the 1870s, he founded the Pittsburgh's Carnegie Steel Company, a step which cemented his name as one of the "Captains of Industry". By the 1890s, the company was the largest and most profitable industrial enterprise in the world. Carnegie sold it to J.P. Morgan in 1901, who created U.S. Steel. Carnegie devoted the remainder of his life to large-scale philanthropy, with special emphasis on local libraries, world peace, education and scientific research. He founded, among other institutions, the Carnegie Corporation of New York, Carnegie Endowment for International Peace, Carnegie Mellon University and the Carnegie Museums of Pittsburgh.
