An early photograph of an x-ray of a halfpenny coin lodged in the gullet of a nine-year old child where it lay for several months. The lower photograph on the left is of Roentgen's x-ray showing part of a needle in a woman's thumb, that on the right shows the forefinger of a gentleman with the bone of the tip broken due to an accident when riding in a gig, a two-wheeled one-horse carriage. It had been only about ten years since Wilhelm Roentgen, professor of physics in Wurtzburg made his famous discovery in 1895 of what he named Roentgen or x-rays. X-rays quickly entered their use in medicine, the first uses for medical imaging.
