What was Wilhelm Roentgen do in 1895?

In 1895, Wilhelm Röntgen discovered X-rays while experimenting with cathode rays in his laboratory. He noticed that a fluorescent screen in his lab began to glow even though it was not in the direct path of the rays, leading him to investigate further. This groundbreaking discovery allowed for the visualization of the internal structures of objects, including the human body, revolutionizing medical imaging and diagnostics. Röntgen's work earned him the first Nobel Prize in Physics in 1901.
