Marie Curie
Marie Curie was the first woman to win a Nobel Prize and the only woman to win the award in two different fields (Physics, 1903; Chemistry, 1911).
In 1898, Marie Curie and Pierre Curie discovered the two radioactive elements polonium and radium.12
They identified these elements while conducting research on the mineral pitchblende, noting that its radioactivity was significantly higher than could be explained by its uranium content alone. The discovery of polonium was announced in July 1898, followed by the discovery of radium in December 1898.32
