Then
Her discoveries opened atomic physics and gave medicine a new tool — radiation — and her two Nobel Prizes (Physics 1903, Chemistry 1911) broke ground for women in science.

Signature idea
Pioneered research on radioactivity; first woman Nobel laureate
Their place in history
1867 - 1934
The question they asked
What is the mysterious “radiation” that uranium gives off, and can new elements be separated from ores?
The Contribution
What this scientist actually did — precisely and plainly.
With her husband Pierre, she purified two new elements and showed that radioactivity is an atomic property, naming the phenomenon itself.
How the Work Advanced Knowledge
The tools, experiments and reasoning behind the discovery.
She developed painstaking chemical separation and precise measurement, processing tonnes of ore by hand to isolate trace amounts of new elements.
Why It Mattered Then / Today
From their own moment in history to the world we live in now.
Today
Radioactive tracers and radiotherapy save lives in medicine, and her measurement techniques became the backbone of nuclear science.
Important Works or Discoveries
Landmarks that carried the idea into the world.
- Discovery of radium and polonium
- Two Nobel Prizes (Physics and Chemistry)
- Mobile X-ray units in war
Nothing in life is to be feared, it is only to be understood.
