In 1901 a bank in Hoboken built a special vault just to hold Andrew Carnegie’s gold bonds from the sale of his steel empire. This episode explores the paradox of the starving immigrant who became a ruthless monopolist and then one of history’s greatest philanthropists. We begin in a weaver’s cottage in Dunfermline and the terrifying boiler-room job of a 12-year-old, then follow his rise through the telegraph office, Colonel Anderson’s library, and the Pennsylvania Railroad’s insider deals.

We explain how Carnegie, who was a systems optimizer rather than an inventor, used the Bessemer process and extreme vertical integration to dominate steel. We set his Gospel of Wealth beside the Johnstown Flood and the bloody Homestead Strike, then follow the sale to J.P. Morgan that created U.S. Steel and his giving: nearly 3,000 libraries, the Peace Palace, Dippy the dinosaur, and an offer to buy independence for the Philippines.
