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.
The first X-ray telescope employing Wolter Type I grazing-incidence optics was employed in a rocket-borne experiment in 1965 to obtain X-ray images of the sun (R. Giacconi et al., ApJ 142, 1274 (1965)).
