A closer look
Nasaw shows how Carnegie's mentor, Tom Scott of the Pennsylvania Railroad, gave him early investment chances that made him wealthy.
He covers the 1892 Homestead strike, a violent clash at a Carnegie plant that damaged his reputation.
Carnegie's essay 'The Gospel of Wealth' argued the rich should give away their fortunes, and he did.
Nasaw also explains how Carnegie kept costs low by tracking every expense in his mills, something few industrialists did in detail at the time. He used those numbers to undercut rivals and buy them out in bad years. The book shows how careful cost accounting became one of his biggest advantages.
The last part of the book covers his giving. Carnegie wrote that the man who dies rich dies disgraced, and he spent his later years funding libraries, schools and peace efforts. Nasaw weighs that giving against the harsh treatment of workers that helped build the fortune, leaving readers to judge both sides.
