Roentgen’s X-Rays Nov. 8th, 1895 not an accident

First Lady of X- Ray

January 6, News Cabled from the London Standard The noise of war's alarm should not distract attention from the marvelous triumph of science which is reported from Vienna. It is announced that Professor Routgen (sic) of the Wurzburg University has discovered a light which for the purpose of photography will penetrate wood, flesh, cloth, and most other organic substances. The Professor has succeeded in photographing metal weights which were in a closed wooden case, also a man's hand which showed only the bones, the flesh being invisible. Instant Renown

Roentgen Legacy Medical x-rays Industrial diagnostics

many wave/particle questions X-rays did not diffract or refract BUT penetrated solids Max von Laue hypothesis-> Friedrich & Knipping exp’ts.

William Lawrence & William Henry Bragg determine wavelength of x-rays Braggs change diagnostic tool for x-rays into tool for studying crystals

Barkla & others bombard different elements with x-rays & find “hard”, “soft” reflections 1914 Henry Gwyn-Jeffries Moseley measures wavelength of reflections: atomic order!

Henri Becquerel was seeking a connection between fluorescence and x-rays when he found … (go, Libby!)
