Maria Skłodowska-Curie, commonly known as Marie Curie, was a pioneering scientist born in Poland in 1867. She is best known for her groundbreaking research on radioactivity, a term she coined. Curie was the first woman to win a Nobel Prize and remains the only person to win Nobel Prizes in two different scientific fields: Physics in 1903 and Chemistry in 1911. Curie's work led to the discovery of the elements polonium and radium. Her research not only advanced the field of nuclear physics but also contributed to medical treatments for cancer. Despite facing significant challenges as a woman in science, her legacy continues to inspire future generations.
