Wilhelm Conrad Röntgen discovered X-rays on November 8, 1895, while studying cathode rays in a glass tube. He wrapped the tube in black cardboard to make it light-tight, but a pale green glow appeared on a barium platinocyanide screen left on a bench. The glow persisted even when he covered the tube with thicker cardboard, and when he held his hand between the tube and screen, he saw his own bones. This unexpected phenomenon led to the discovery of X-rays, which can penetrate materials that block visible light.

Why a faint green glow on a Würzburg lab bench in November 1895 invented modern medicineIndexed:
On the evening of 8 November 1895, Wilhelm Conrad Röntgen, professor of physics at the University of Würzburg, was experimenting with a Crookes–Hittorf cathode ray tube wrapped in black cardboard to make it light-tight. As he discharged the induction coil through the sealed tube, he saw a faint green shimmer across the room — fluorescence on a small barium platinocyanide screen lying on a nearby bench. Cardboard could not stop whatever was passing through it. For seven weeks Röntgen worked alone in his laboratory at the Physikalisches Institut, eating and sleeping there, telling no one. He found the rays passed through wood, paper, and flesh — but not bone, not lead. On 22 December 1895 he placed his wife Anna Bertha Ludwig's left hand on a photographic plate and exposed it for fifteen minutes. The bones of her fingers, and her wedding ring, appeared on the plate. She is reported to have said: I have seen my death. He published Über eine neue Art von Strahlen — On a New Kind of Rays — on 28 December 1895, calling them X-rays because their nature was unknown. Within months hospitals across Europe and America were using X-rays to find bullets and broken bones. In 1901 Röntgen received the first Nobel Prize in Physics. He refused to patent the discovery, donated his prize money to the university, and died in 1923 nearly bankrupt from postwar inflation. Sources: [1] Wikipedia — Wilhelm Röntgen [2] W. C.

November 8th, [music] 1895, a green glow invents modern medicine.
Wilhelm Conrad Röntgen, physics [music] professor at the University of Würzburg.
He was 50 years old, quiet, methodical, with no taste for fame. Upstairs at [music] the Physicalisches Institute, his small laboratory sat above the corridors.
He was studying cathode rays, glass tubes, [music] high voltage, the new mystery. Carefully, he wrapped the tube in black cardboard to make it light tight.
Late on the evening of November 8th, curtains drawn, he discharged the coil.
Across the darkened room, a pale green shimmer flickered against the wall.
It came from a barium platinocyanide [music] screen left by chance on a bench. It made no sense. Cathode rays die in air within inches.
He covered the tube with thicker card, >> [music] >> then more, still the glow remained. He held his hand between tube and screen [music] and saw his own bones.
He told no one. He locked the door, eating and sleeping in the laboratory.
For seven solitary weeks, he worked alone, methodical, repeating [music] every test.
On December 22nd, he called his [music] wife, Anna Bertha, into the lab. For 15 long minutes, she held her hand still on the photographic plate. [music] On the developed plate, her bones, her knuckles, her wedding ring.
Staring at the [music] image, she whispered, "I have seen my death."
On December 28th, he submitted [music] his short 10-page scientific paper.
He called them X-rays, the X for unknown, their nature still mysterious.
By January, newspapers across Europe carried the news. The world followed.
Within weeks, bullets located, bones set, lives saved in every hospital.
In America, Edison built his own X-ray apparatus [music] within weeks. Röntgen refused to patent his discovery. He wanted it free for everyone.
Early operators [music] paid the price.
Burns, lost hands, lost skin, lives. On January 23rd, >> [music] >> he showed von Kölliker's hand, the skeleton on screen.
The room rose calling them Röntgen rays.
>> [music] >> He refused the honor.
For the first time in history, doctors could see inside the living body.
In 1901, he received the first Nobel Prize in physics.
He donated the entire prize money back [music] to the University of Würzburg.
After the war, German inflation destroyed his savings, leaving him poor.
On February 10th, 1923, he died in Munich of cancer.
Today, billions of X-ray scans [music] are performed in hospitals each year.
From one faint flicker in one dark room, modern medicine itself.
He saw the invisible and refused [music] until the end to own it.
