The autobiography opens in Dunfermline, Scotland, where Carnegie was born in 1835 to a damask weaver. He dwells on his grandparents, his radical and book-loving relatives, and above all a household marked by honor, independence, and self-respect. When power looms ended his father's handweaving trade, the family emigrated to the United States, settling near Pittsburgh in pursuit of a better start.
As a boy of thirteen Carnegie went to work to help support the family, first in a cotton factory and then as a telegraph messenger. He describes saving every penny for home, learning the telegraph by watching and practicing, and being singled out for early promotion. A turning point was Colonel James Anderson, who opened his private library to working boys; Carnegie credits this access to books with shaping his mind and later inspiring his own library gifts.
His career advanced through the Pennsylvania Railroad under Thomas A. Scott, where he learned management and made his first investments. He then concentrated on manufacturing, building iron and bridge works and finally turning to steel. He recounts the firm's edge in adopting chemistry, replacing rule-of-thumb furnace men with trained method, and reinvesting earnings, summed up in his rule to put all good eggs in one basket and watch that basket.
The book gives close attention to partners and to labor. Carnegie portrays himself as proud of long, friendly relations with his workmen and as disposed to grant their demands, while insisting that agreements once signed must be kept by both sides. He addresses the bitter Homestead strike of 1892, which occurred during his absence in Scotland, as the one serious break in that record, and reflects on what he sees as the proper relations between capital and labor.
The final chapters turn to the gospel of wealth. Having sold the Carnegie Steel Company to J. P. Morgan, Carnegie resolves to stop accumulating and begin the harder task of wise distribution. He describes pensions for his workmen, free public libraries, the Carnegie Institution of Washington, the Hero Fund, and his hopes for peace, presenting great surplus wealth as a trust to be administered for the lasting good of others.
