World's First X-Ray (1895): Röntgen's wife hand
In 1895 Wilhelm Conrad Röntgen, professor of physics the University of Wurburg in Germany, was doing experiments with electrical discharges in evacuated glass tubes. Late in 1895 Wilhelm Röntgen was alone at night doing his experiments, this time in the dark and noticed a glow was produced on the wall, which he knew was not caused by fluorescence or visible light. He named these new, unidentified rays 'X' or if you prefer; X-rays. After several months of playing with his discovery he noticed that objects place in the path of the rays cast shadows and created images on the wall. Soon after he used a photgraphic plate and had his wife, Frau Röntgen, place her hand in the path of the X-rays, creating the world's first X-ray picture. In 1901 Wilhelm Röntgen was awarded the very first Nobel Prize in Physics for this discovery.
