Two excellent reads not specifically scientific but rather biographical accounts of two of the greats minds of all time:
American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin
Einstein: His Life and Universe by Walter Isaacson
Both really offer insight into true genius and show them warts and all...I was somewhat familar with Einstein's life and times but really did not know much about Oppie, now I do!!
If you enjoy pure science and the humanity that often gets taken for granted when looking at the minds behind the science.
