A German Physicist, Wilhelm Roentgen, did research on cathode rays in 1895 with a Crookes tube. He found that fluorescent crystals glowed when he activated the tube. Even when he blocked visible light it kept glowing so he named this effect X-Rays.

Edison. However there are some very interesting hieroglyphic depictions from ancient Egypt that show people working with large cathode-ray shaped objects. Historians have no idea exactly what these objects signify, but some (less scientific, more new-agey) individuals believe the Egyptians actually harnessed this technology.
