There’s only one thing Dr. John Haldane loved more than running dangerous experiments on himself—running them on his son Jack. But the duo would revolutionize our understanding of the human body.

When Charles Lindbergh's sister-in-law developed heart trouble, he teamed up with a Nobel-Prize-winning doctor to save her. He had no idea the dark paths his work would lead him down, including Nazi politics and eugenics...

Exactly a century ago, teacher John Scopes was charged with the “crime” of teaching evolution. But Scopes was hardly a defiant Galileo, nobly standing up for truth.
