Yes...books bound in human skin.
In January of 1869, Dr. John Stockton Hough stooped over an autopsy table to examine the emaciated corpse of Mary Lynch.
When Dr. Hough opened Lynch's chest cavity to inspect her tuberculosis-wracked lungs, he noticed an unusual cyst in her pectorals. Under a microscope, his vision swam as countless tiny worms wriggled around. Lynch was the first known case of trichinosis in Philadelphia.
However, Dr. Hough is not most famous for this discovery but, rather, for what he did immediately afterward: He cut a slice of Lynch's skin from her thighs and preserved it in a chamber pot. Decades later, Dr. Hough used this preserved human skin to bind three of his most prized books, all of which dealt with women's health.
