Wilhelm conrad roentgen was already working on the effects of cathode rays during 1895, before he actually discovered x-rays. The nobel prize in physics 1901 wilhelm conrad r ntgen r ntgen was in his laboratory studying how cathode-ray tubes emit light he discovered that the impact of cathode rays on the glass vacuum tube was generating a new kind of invisible ray. On this day in 1895, physicist wilhelm conrad rontgen (1845-1923) becomes the first person to observe x-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible rontgen's discovery occurred accidentally in.
