[00:00:01]November 8th, [music] 1895, a green glow invents modern medicine.

[00:00:06]Wilhelm Conrad Röntgen, physics [music] professor at the University of Würzburg.

[00:00:11]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.

[00:00:22]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.

[00:00:31]Late on the evening of November 8th, curtains drawn, he discharged the coil.

[00:00:36]Across the darkened room, a pale green shimmer flickered against the wall.

[00:00:41]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.

[00:00:51]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.

[00:01:00]He told no one. He locked the door, eating and sleeping in the laboratory.

[00:01:04]For seven solitary weeks, he worked alone, methodical, repeating [music] every test.

[00:01:10]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.

[00:01:23]Staring at the [music] image, she whispered, "I have seen my death."

[00:01:28]On December 28th, he submitted [music] his short 10-page scientific paper.

[00:01:33]He called them X-rays, the X for unknown, their nature still mysterious.

[00:01:38]By January, newspapers across Europe carried the news. The world followed.

[00:01:44]Within weeks, bullets located, bones set, lives saved in every hospital.

[00:01:50]In America, Edison built his own X-ray apparatus [music] within weeks. Röntgen refused to patent his discovery. He wanted it free for everyone.

[00:01:59]Early operators [music] paid the price.

[00:02:01]Burns, lost hands, lost skin, lives. On January 23rd, >> [music] >> he showed von Kölliker's hand, the skeleton on screen.

[00:02:10]The room rose calling them Röntgen rays.

[00:02:12]>> [music] >> He refused the honor.

[00:02:14]For the first time in history, doctors could see inside the living body.

[00:02:19]In 1901, he received the first Nobel Prize in physics.

[00:02:23]He donated the entire prize money back [music] to the University of Würzburg.

[00:02:27]After the war, German inflation destroyed his savings, leaving him poor.

[00:02:33]On February 10th, 1923, he died in Munich of cancer.

[00:02:38]Today, billions of X-ray scans [music] are performed in hospitals each year.

[00:02:43]From one faint flicker in one dark room, modern medicine itself.

[00:02:47]He saw the invisible and refused [music] until the end to own it.
