How did a faint glow on a lab bench lead to seeing inside living people?
In November 1895, Röntgen saw a shimmer he could not explain, and within weeks doctors were looking at bones inside living hands.
▶ Start the storyBy accident, and then by paying attention to something small. In 1895 the German physicist Wilhelm Röntgen was investigating what happens when electricity passes through . In the late afternoon of 8 November he set out to test an idea, and while doing so he noticed a faint shimmering from a bench a few feet away from the tube. To be sure, he tried several more discharges and saw the same shimmering each time. Something invisible was crossing the room.
He spent the following weeks eating and sleeping in his laboratory, investigating the new rays. He temporarily named them X-rays, using the mathematical designation X for something unknown. Röntgen thus saw the first radiographic image: his own flickering ghostly skeleton on the screen. He also made a photograph of his wife's hand, the first photograph of a human body part using X-rays. When she saw it, she said "I have seen my death."
He wrote a preliminary report and, on 28 December 1895, submitted it to a physical-medical society's journal, the first paper written on X-rays. Röntgen immediately noticed that the rays could have medical applications, and he sent a letter to physicians around Europe in January 1896. The first use of X-rays under clinical conditions came on 11 January 1896, when John Hall-Edwards in Birmingham a needle stuck in a colleague's hand.
Interest exploded. As many as 49 essays and 1044 articles about the new rays were estimated to have been published in 1896 alone. Röntgen received the first Nobel Prize in Physics, in 1901.

Recap
A shimmer on a bench led Röntgen to X-rays, which let doctors see inside the body within weeks, though early users also met their dangers.
💡 A trick to remember it · X marks the unknown, and the unknown showed the bones.
Surprising fact · Röntgen called them X-rays because X stands for something unknown, and the name stuck over his objections to Röntgen rays.
