In this sweeping biography, acclaimed historian David Nasaw brings to life the complex and often contradictory figure of Andrew Carnegie—industrial titan, philanthropist, peace advocate, and embodiment of the American dream. Born in Scotland in 1835 to a poor weaver’s family, Carnegie immigrated to the United States and rose from bobbin boy to the richest man in the world through his steel empire.Nasaw explores Carnegie’s meteoric rise, his ruthless business tactics, and his later-life transformation into a generous benefactor who gave away nearly all his fortune. Drawing on unprecedented access to Carnegie’s personal papers—including unpublished autobiography chapters, private letters, and correspondence with presidents and intellectuals—Nasaw paints a vivid portrait of a man who shaped modern capitalism and philanthropy, yet remained an enigma.Spanning nearly a century of social and political upheaval, Andrew Carnegie is both a compelling life story and a lens into the forces that forged America’s Gilded Age.
