German Scientists Discover X-rays On this day in the year 1895, a mechanical physicist Wilhelm Conrad Rontgen 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 his Wurzburg, Germany, lab, where he was testing whether cathode rays could pass through glass when he noticed a glow coming from a nearby chemically coated screen. He dubbed the rays that caused this glow X-rays because of their unknown nature, an achievement that earned him the first Nobel Prize in Physics in 1901. X-ray is an an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light. It is a photographic or digital image of the internal composition of something, especially a part of the body, produced by X-rays being passed through it and being absorbed to di
