Wilhelm Röntgen, India, 1995. Stamps depicting individual crystallographers are sometimes issued by countries to commemorate the birth or death anniversaries of their significant national crystallographers, [12] For example, on August 6, 1996, the British postal service (Royal Mail) issued a stamp honouring Dorothy Hodgkin, a pioneer of protein crystallography (Great Britain's first female ...
Röntgen Memorial Site, Röntgenring 8, Würzburg. The Röntgen Memorial Site in Würzburg, Germany, is dedicated to the work of the German physicist Wilhelm Conrad Röntgen (1845–1923) and his discovery of X-rays, for which he was granted the first Nobel Prize in physics, in 1901. It contains an exhibition of historical instruments, machines ...
This laid way for spectrochemical analysis in laboratory and astrophysical science. Bunsen and Kirchhoff applied the optical techniques of Fraunhofer, Bunsen's improved flame source and a highly systematic experimental procedure to a detailed examination of the spectra of chemical compounds. They established the linkage between chemical ...
In early 1896, there was a wave of excitement following Wilhelm Conrad Röntgen's discovery of X-rays on 5 January. During the experiment, Röntgen "found that the Crookes tubes he had been using to study cathode rays emitted a new kind of invisible ray that was capable of penetrating through black paper". [8]

March 22 – Auguste and Louis Lumière make what is probably the first presentation of a projected celluloid film moving picture, the 46-second Workers Leaving the Lumière Factory , to members of the Société d'encouragement pour l'industrie ...
Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
