Inadvertently on November 8, 1895, Wilhelm Conrad Roentgen, a professor of physics and rector of the Julius Maximilian University of Wiirzburg, Germany, discovered the X-rays. Roentgen stumbled upon the X-rays by covering an electrified cathode ray tube with black paper for another of his experiments, he noticed a faint fluorescence from a barium platinocya-nide-coated screen across the room. He correctly hypothisied that the glow was caused by an unknown form of high-energy radiation emitted from the electrified cathode ray tube, he called this “X-radiation.”

History. X-rays were discovered in 1895 by Wilhelm Conrad Roentgen (1845-1923) who was a Professor at Wuerzburg University in Germany. Working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube.
- Wilhelm Conrad Roentgen and the Discovery of X-Ray Beams
Discovery of X-ray Beams. Wilhelm Roentgen was already working on the effects of cathode rays during 1895, before he actually discovered X-rays. His experiments involved the passing of electric current through gases at extremely low pressure.
