Title:: Roentgen's Discovery of the x-ray
Description:: This photo is one of the first x-ray images, made by Wilhelm Roentgen in 1895. It shows the bones in his wife's hand. The calcium in her bones absorbed much of the energy from the x-ray beam and cast a shadow. Notice the shadow of her ring.

To learn about the early history of x-rays, see Roentgen's Discovery of the x-ray and, to learn more, check out this illustrated article from Stanford University.
