There's always the remarkable story of Rasputin's death. He was an advisor to Nicholas II of Russia, and refused to die after being poisoned, shot, and beat.
"The would-be killers first gave the monk food and wine laced with cyanide, however, when Rasputin seemingly failed to respond to the poison, they shot him at close range and left him for dead. In spite of these murderous measures, Rasputin revived shortly thereafter and made an attempt to flee the palace grounds, only to be intercepted by his assailants who shot him again and viciously beat him. They then bound Rasputin, who was remarkably still alive, and threw him into the freezing Neva River. His battered body was found several days later and it was reported that there was water in his lungs, indicating that he finally died by drowning."
I will also add, it's pretty neat that Ernest Shackleton's famed lost ship, the Endurance, was found 100 years to the day that Ernest was buried.
American Prometheus, the Triumph and Tragedy of J. Robert Oppenheimer, by Kai Bird and Martin J. Sherwin.
I wanted to check it out before the movie comes out, and I highly recommend it for a very in depth view of his life.
I also recently finished On the Origin of Time, by Thomas Hertog, which I also recommend. It's about Stephen Hawking's final ideas and theories, told by one of his closest proteges. There are some incredible ideas in this book that I had never heard of before, and I'm a cosmology nerd.
