Marie Curie

Learning Across Borders

Marie Curie was born Maria Skłodowska in Warsaw in 1867, when the city was part of the Russian Empire. Her parents were teachers, and she grew up valuing education. Universities in Warsaw did not admit women, so she continued learning through informal classes and worked as a governess to help support her family.

In 1891, she moved to Paris and enrolled at the University of Paris, often called the Sorbonne. She studied physics and mathematics in French, earned degrees in both subjects, and began laboratory research. In Paris she met physicist Pierre Curie. They married in 1895 and became research partners.

Investigating Radioactivity

Physicist Henri Becquerel had discovered that uranium gave off an unusual kind of radiation. Curie chose this phenomenon for her research and made careful measurements of different minerals. She concluded that the radiation came from the atoms themselves and used the word "radioactivity" for the effect.

In 1898, Marie and Pierre Curie announced evidence for two previously unknown elements. They named one polonium, after Poland, and the other radium. Separating radium from tons of mineral residue took years of physically demanding work. Their results helped open a new field for studying atoms and radiation.

Two Different Nobel Prizes

In 1903, Marie Curie shared the Nobel Prize in Physics with Pierre Curie and Henri Becquerel for research on radiation. She was the first woman to receive a Nobel Prize. After Pierre died in a street accident in 1906, she continued their research and became the first woman professor at the University of Paris.

Curie received the 1911 Nobel Prize in Chemistry for discovering polonium and radium, isolating radium, and studying its compounds. She was the first person to receive two Nobel Prizes and remains the only person awarded Nobels in two different scientific categories.

Science in Service of Medicine

During World War I, Curie organized mobile X-ray units that helped doctors locate bullets and broken bones. She also trained people to operate the equipment. Her work connected laboratory science with practical medical care.

Curie died in 1934 from aplastic anemia, an illness linked to long exposure to radiation at a time when its dangers were not well understood. Her discoveries transformed physics, chemistry, and medicine, while her career opened doors for women in scientific research.
