1895: German physicist, Wilhelm Conrad Rontgen, observed the first X-Ray in his Wurzburg, Germany lab. He was trying to determine whether cathode rays could pass through glass and noticed a glow coming off a chemically coated screen.
He dubbed the ray ‘X’ because of the unknown nature of the ray. He won every German accolade, streets, towns, (probably babies) and honorary doctorates and memberships in learned German society. In 1901, he won the Nobel Prize in physics.
