In this magisterial, acclaimed biography twenty-five years in the making, Kai Bird and Martin Sherwin capture Oppenheimer’s life and times, from his early career to his central role in the Cold War. This is biography and history at its finest, riveting and deeply informative. “A masterful account of Oppenheimer’s rise and fall, set in the context of the turbulent decades of America’s own transformation. It is a tour de force.” —Los Angeles Times Book Review “A work of voluminous scholarship and lucid insight, unifying its multifaceted portrait with a keen grasp of Oppenheimer’s essential nature…. It succeeds in deeply fathoming his most damaging, self-contradictory behavior.” —The New York Times
