Who made the discovery of X-rays?

Wilhelm Conrad Röntgen made the discovery of X-rays. In 1895, while experimenting with cathode rays, Röntgen noticed a fluorescent effect on a screen located several feet away from the cathode tube. He hypothesized the presence of a new type of ray that could pass through materials opaque to light. Through further experiments, Röntgen discovered that these unknown rays could create images of objects on a photographic plate placed nearby, thus revolutionizing the field of modern medicine and earning him the first Nobel Prize in Physics in 1901.
