Wilhelm Conrad Röntgen è stato un fisico tedesco.

Il suo nome è legato alla scoperta, avvenuta l'8 novembre 1895, della radiazione elettromagnetica nell'intervallo di frequenza oggi noto come raggi X. L'annuncio di questa scoperta fu dato il 5 gennaio 1896. Il luogo della scoperta oggi è un piccolo museo, la Röntgen-Gedächtnisstätte. A Röntgen fu assegnata la laurea onoraria di dottore in medicina dall'Università di Würzburg.

Per questa scoperta, Röntgen ricevette il primo Premio Nobel per la fisica nel 1901. La motivazione fu "in riconoscimento dello straordinario servizio reso per la scoperta delle importanti radiazioni che in seguito presero il suo nome". Röntgen donò il premio in denaro alla sua università. Come Pierre Curie avrebbe fatto alcuni anni più tardi, Röntgen rifiutò di brevettare questa scoperta per motivi morali; non volle nemmeno che le nuove radiazioni prendessero il suo nome, anche se questo avvenne, indipendentemente dalla sua volontà.

Frasi Wilhelm Conrad Röntgen

„I did not think; I investigated.“

— Wilhelm Röntgen
Context: I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. … The effect was one which could only be produced, in ordinary parlance, by the passage of light. No light could come from the tube, because the shield which covered it was impervious to any light known, even that of the electric arc. … I did not think; I investigated. I assumed that the effect must have come from the tube, since its character indicated that it could come from nowhere else. I tested it. In a few minutes there was no doubt about it. Rays were coming from the tube which had a luminescent effect upon the paper. I tried it successfully at greater and greater distances, even at two metres. It seemed at first a new kind of invisible light. It was clearly something new, something unrecorded.

„I am pursuing my investigations, and as fast as my results are verified I shall make them public.“

— Wilhelm Röntgen
Context: I am not a prophet, and I am opposed to prophesying. I am pursuing my investigations, and as fast as my results are verified I shall make them public.

Context: Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had penetrative power to a degree hitherto unknown. They penetrated paper, wood, and cloth with ease; and the thickness of the substance made no perceptible difference, within reasonable limits. … The rays passed through all the metals tested, with a facility varying, roughly speaking, with the density of the metal. These phenomena I have discussed carefully in my report to the Würzburg society, and you will find all the technical results therein stated.
