Back in the early 80s, Rudolf Peierls did a talk to about a hundred of us at Birmingham University about the war, quantum mechanics and Heisenberg. It must have seemed desperate in 1940 in the dark days with worries about family &c.
I've never heard his eccentricity attributed to wartime trauma (obviously I'll always be open to new information on that...)
* "When The Voice of the Dolphins was published, Leo hadn’t worked in physics in over a decade" fails to mention he switched to biology.
* "His first real permanent address in America was in La Jolla, where he retired" fails to mention he helped setup the Salk Institute (in La Jolla) and was a fellow there.
Rhodes' follow-up, "Dark Sun: The Making Of The Hydrogen Bomb", basically continues the story where TMAB left off. The narrative gets a bit more fractured and factual, focused on the question of how to safeguard nuclear weapons and what their political/military/diplomatic purpose is. But it does wrap up the J. Robert Oppenheimer story.
Once one has read these two, I strongly recommend "American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer"  by Bird and Sherwin. Also extremely well written.
Another good one that I got recently is Arabia Felix , a rather obscure Danish book from 1962 from NYRB. A minor classic.
I'm not a war buff by any stretch, but I can recommend Antony Beevor. Sometimes his books devolve into exhausting, never-ending play-by-plays of tank and troop movements, but both Stalingrad and The Fall of Berlin  and were fascinating just for his ability to conjure up the time and place. Inside the Third Reich was similarly interesting, even it's known to be a flawed narrative.
I also recently read Bad Blood, about Theranos, which was excellent. Literary-wise not quite on the same level, though.
Got any recommendations?
