When did Conrad Wilhelm Roentgen discover x-ray?

Conrad Wilhelm Roentgen discovered X-rays on November 8, 1895. This significant moment in medical history occurred while he was experimenting with cathode rays in a laboratory. Roentgen observed that a fluorescent screen in his lab began to glow even though it was not in the direct path of the cathode rays. Intrigued by this phenomenon, he continued his investigations and ultimately created the first X-ray images, including one of his wife’s hand, which clearly showed her bones and wedding ring.

The date of discovery is crucial not only for historical context but also for understanding the development of radiology as a medical field, which started with Roentgen's findings. His work laid the foundation for the use of X-rays in diagnostics and opened the door to advanced imaging techniques that have developed throughout the 20th and 21st centuries.
