This is an incredibly well researched, detailed account of all aspects of Einstein's life, personal, scientific and political that I can highly recommend to anybody interested. I learned heaps I didn't know and had the record set straight on a number of points, mainly regarding Einstein's political views, how they changed over time and his level of support for setting up the Manhattan Project.
I read the book with a specific research agenda, which was to independently form an opinion as to whether Einstein was autistic, an idea not first suggested by me and not on the author's mind either. Conclusion: Yep, autisticker than an autistic person with autism.
Towards the end there is an account of how Einstein was affected by and responded to McCarthyism. He was opposed, seeing in it the oppression of free speech and free thought characteristic of both Fascism and Communism. The author takes the view that McCarthyism was a passing fad, doomed to fail in the long term because of the greatness of the American Constitution. I found this level of complacency offensive to all the victims of McCarthy, all the people who spoke up in defense of freedoms and all the people who defended the constitution legally.
On it's own the constitution is nothing; without those people willing to risk reputation, career, even liberty, would McCarthyism have been a "passing fad"? Given the current political situation, we need such people more than ever. You disappoint me in this, Isaacson. Einstein, who used his world famous name to stand up for moderation, tolerance and freedom of thought and speech, does not.
Still, overall an excellent book.
