German scientist discovers X-rays. On this day in 1895, physicist Wilhelm Conrad Rontgen (1845-1923) becomes the first person to observe X-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible.
It was soon discovered that Rontgenâs Crookes tubes were unreliable and hindered the effectiveness of the X-ray. William Coolidge greatly contributed to the improvement of the X-ray with his 1913 invention of the Coolidge tube, which used a tungsten filament.
