"This fascinating and thoughtful book brilliantly captures the political and scientific struggles of the early atomic age. Oppenheimer's triumphs and trials show how public policy, scientific genius and private character become interwoven. Bird and Sherwin have triumphed in turning their prodigious research about the father of the bomb into a poignant narrative."
--Walter Isaacson

"American Prometheus is the best--most thoroughly researched and most convincingly argued--study of J. Robert Oppenheimer to date. It is not only a great biography but also a cautionary tale about the excesses of government in a time of fear. No one interested in 20th-century America can afford to ignore this book."
--Robert Dallek

"The political drama is enhanced by the close attention to Oppenheimer's personal life, ...restoring human complexity to a man who had been both elevated and demonized."
-Publishers Weekly, starred review

"Compelling, definitive...Funneling more than 25 years of research into a captivating narrative, the authors bring needed perspective to Oppenheimer's radical activities in the 1930s, and they reprise the familiar story of the Manhattan Project thoroughly...Where Bird and Sherwin are without peer, however, is in capturing the humanity of the man behind the porkpie hat."
-Booklist, starred review
