Episode 23: Bone Portraits


A darkened laboratory with an eery green glow; a photograph of the bones of a woman’s hand published on the front pages of newspapers throughout the globe; mysterious rays that promise to change medicine forever but also cause horrific disease in their champions and pioneers. In this episode, called Bone Portraits, I tell the story of two men — Wilhelm Roentgen, the discoverer of x-rays who would later win a Nobel Prize, and Clarence Dally, the first victim of x-ray radiation. Listen to the thrilling conclusion of our to part series on the dawn of diagnostic imaging! We’ve got all this, plus a double-header #AdamAnswers, in Episode 23 of Bedside Rounds, a tiny podcast about fascinating stories in clinical medicine.
