New York Review of Books "An excellent piece of science writing... Cassidy does not so much exculpate Heisenberg as explain him, with a transparency that makes this biography a pleasure to read."
Los Angeles Times "A page-turner."
American Scientist "[An] excellent discussion of science, society, and the influence ... Read moreof the individual scientist."
Physics Today "An excellent work in its comprehensiveness and accuracy, and in its success in recreating the personal drama of one of the greatest and most influential scientists of this century."
Times Higher Education "Exhaustively detailed yet eminently readable, this is an important book."
Publishers Weekly (starred review) "An excellent follow up on Cassidy's earlier masterwork Uncertainty. Cassidy offers deep insight into Heisenberg's role as a principle founder of quantum mechanics and as the leading German physicist during the WWII years in the quest for atomic energy and weapons."
Benjamin Bederson, physics professor emeritus, New York University, editor-in-chief emeritus of the American Physical Society, and Manhattan Project member "A must-read book about key players in science and world history."
Gerald Holton, research professor of physics and history of science, emeritus, Harvard University, and author of Einstein, History, and Other Passions and coeditor of Einstein for the 21st Century "Cassidy has written the definitive biography of a great and tragic physicist."
