Who produced X-rays in a high voltage discharge tube in 1895?

Wilhelm Roentgen is credited with the discovery of X-rays in 1895 while experimenting with a high voltage discharge tube. During his experiments, he noticed a fluorescent glow coming from a nearby screen when he activated the tube, even though it was shielded from direct light. This phenomenon led him to investigate further, ultimately resulting in the realization that he had discovered a new type of radiation, which he called X-rays due to their unknown nature at the time.

Roentgen's discovery was groundbreaking and had a profound impact on medical imaging and diagnostics, revolutionizing the field by allowing for internal structures to be viewed without invasive procedures. His work earned him the first Nobel Prize in Physics in 1901, solidifying his place in history as a pioneer of medical imaging technology.
