On November 8, 1895, Wilhelm Conrad Röntgen accidentally stumbled upon one of the most transformative scientific discoveries in human history while tinkering in his laboratory at the University of Würzburg, Germany. Experimenting with cathode ray tubes, Röntgen noticed a curious phenomenon: a nearby fluorescent screen began to glow, even though the tube was completely covered in black cardboard.

Intrigued, he placed various objects between the tube and the screen, including his wife's hand, and observed something extraordinary—he could see the bones inside her flesh, creating the first "X-ray" image. This accidental breakthrough would revolutionize medicine, allowing physicians to peer inside the human body without invasive procedures.

Röntgen initially called these mysterious rays "X-rays" because of their unknown nature, and he spent weeks meticulously documenting his findings. In a stroke of scientific serendipity, he had uncovered a technology that would fundamentally change medical diagnostics, forensic investigation, and even industrial testing.

The scientific community was initially skeptical, but within months, X-ray machines were being used in hospitals worldwide. Röntgen would go on to win the first Nobel Prize in Physics in 1901, cementing his place in scientific history—all because of a curious glowing screen on a November afternoon.
