This book is the groundbreaking portrait of a colossus who dominated half a century of American history and planted the seeds for much of today's conservative political landscape. Hoover transformed a scandal-riddled law-enforcement backwater, into a modern machine-one just as oppressive as it was promising. He rose to power and then stayed there, decade after decade, using the tools of the state to create a personal fiefdom unrivaled in U.S. history. Beverly Gage's monumental work explores the full sweep of Hoover's life and career, from his birth in 1895 to a modest Washington civil-service family to a strongarm for white supremacists and the politicized Christian right, serving eight presidents.
