Marie Curie was born in 1867 in Warsaw, Poland. Today she is remembered for her research on radioactivity.
Curie was determined. Women were not allowed to attend university in Poland, so she studied in secret and later moved to Paris to continue.
In 1891, Curie moved to Paris to study physics and mathematics at the Sorbonne. In 1898, Curie discovered two new elements, polonium and radium. Then, in 1903, Curie became the first woman to win a Nobel Prize, in physics.
Later, in 1911, Curie won a second Nobel Prize, this time in chemistry. In 1914, Curie helped equip ambulances with X-ray machines to treat soldiers in World War I. (Element: a pure substance made of only one kind of atom.)
Curie died in 1934. She is still the only person to win Nobel Prizes in two different sciences.
