X-raysIn 1896, German scientist, Wilhelm Röntgen announced his discovery of X-rays. He sent copies of his manuscript and some of his X-ray photographs to several renowned physicists and friends, including Lord Kelvin in Glasgow and Henri Poincaré in Paris. Four days later, on 5 Jan 1896, Die Presse published the news in a front-page article which described the discovery and suggested new methods of medical diagnoses might be made with this new kind of radiation. One day later, the London Standard cabled the news to other countries around the world about the “a light which for the purpose of photography will penetrate wood, flesh, cloth, and most other organic substances.” It printed the first English-language account the next day. |
