Praised by both historians and former Los Alamos weapon engineers and scientists alike, the book is considered a general authority on early nuclear weapons history, as well as the development of modern physics in general, during the first half of the 20th century. According to a citation on the first page of the book, Nobel Laureate Isidor Rabi, one of the prime participants in the dawn of the atomic age, said about the book, "An epic worthy of Milton. Nowhere else have I seen the whole story put down with such elegance and gusto and in such revealing detail and simple language which carries the reader through wonderful and profound scientific discoveries and their application." In 2012 the book was reissued as a 25th anniversary edition with a new foreword by Rhodes.
