American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer   Kai Bird and Martin J. Sherwin
Excellent biography of Oppenheimer. I’ve been fascinated with him since I was young. Focuses in great detail on the witch hunt to rescind his security clearance during the hysteria of the McCarthy era, as the subtitle indicates. Difficult and infuriating to wade through the extensive excerpts from the transcripts. Very well done and very interesting.
