Andrew Carnegie

1835–1919 · The largest cash fortune in American history

From a Dunfermline bobbin boy in an Allegheny cotton mill to $480 million in cash from the 1901 sale of Carnegie Steel to J.P. Morgan — the largest personal cash-out in nineteenth-century American business history. The Bessemer steel deployment, the vertical integration, the Homestead Strike, the 1889 Gospel of Wealth, the 2,509 free public libraries, and the systematic giving-away of 90 percent of the fortune during his own lifetime. Twelve sections plus sources, framework applied throughout, with direct cross-link to Carnegie’s own 1889 Gospel of Wealth essay in the Institute Reading Room.

A note from the Institute

The Carnegie case is the fourth entry in the Institute’s Historical Case series and completes the four-case set of American concentrated-fortune archetypes: Vanderbilt (industrial fortune that dissipated), Rockefeller (industrial fortune that endured), Buffett (modern investment fortune), and now Carnegie (industrial fortune given away during the founder’s own lifetime). The four cases together are the classical American reference set for the concentrated-wealth-preservation-versus-distribution debate.

What distinguishes the Carnegie case is that his own primary manifesto — the 1889 Gospel of Wealth essay, arguably the founding document of modern American philanthropy — is already available for direct reading in the Institute Reading Room. This memo is the practitioner interpretation. Carnegie’s own compressed argument is one row up. Read both.

The document is 14 pages. Written in plain English. Sources cited. Framework applied. The Homestead Strike is treated honestly.
