Well, first off - Walter Isaacson is a genius. I loved the focus he took with this book.
I feel as if I know this man Einstein. I understand the things that were important to him. I get that brilliance thing, and before reading this I had no idea that the explosions of scientific genius were largely related to the one discovery.
I also had no idea about Einstein's political involvement and pacifist views. Isaacson interjected nothing of his own views or politics; this is solely a relating of Einstein's life with no judgement or opinion.
Edward Herrmann is my absolute favourite narrator of all time, and he does this book justice. I do love that man's voice.
I've read a few of Isaacson's other books, and am very glad I own this one. It is excellent.
