Andrew Carnegie (pron.: /kɑrˈneɪɡi/ kar-NAY-gee, but commonly /ˈkɑrnɨɡi/ KAR-nə-gee or /kɑrˈnɛɡi/ kar-NEG-ee; November 25, 1835 – August 11, 1919) was a Scottish-American industrialist who led the enormous expansion of the American steel industry in the late 19th century. He was also one of the highest profile philanthropists of his era; his 1889 article "Wealth" (known more commonly—particularly in colloquial parlance—as "The Gospel of Wealth") remains a formative advisory text for those who aspire to lead philanthropic lives.
