“The definitive biography.... Oppenheimer’s life doesn’t influence us. It haunts us.” —Newsweek

“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

“There have been numerous books about Oppenheimer but they can't touch this extraordinary book's impressive breadth and scope.” —The Miami Herald

“The first biography to give full due to Oppenheimer’s extraordinary complexity.... Stands as an Everest among the mountains of books on the bomb project and Oppenheimer, and is an achievement not likely to be surpassed or equaled.” —The Boston Globe
