Discovery of Radium
The discovery of radium, a highly radioactive element, was announced by the husband-and-wife team of Marie and Pierre Curie on December 26, 1898. Born in Warsaw, Poland, Marie Curie showed remarkable aptitude in physics and moved to Paris in 1891 to study at the Sorbonne, where she later met Pierre. Their research focused on pitchblende, a uranium ore, which revealed higher radioactivity levels than pure uranium, suggesting the existence of previously unknown elements. The Curies isolated radium and confirmed its existence by March 1902, along with another element named polonium, honoring Marie's homeland. Their groundbreaking work earned them the Nobel Prize for Physics in 1903, making Marie the first woman to receive a Nobel Prize. She later won a second Nobel Prize in Chemistry in 1911 for her efforts in isolating these elements. Tragically, Marie Curie's prolonged exposure to radioactive materials likely contributed to her death from leukemia in 1934. The significance of their discoveries has had lasting impacts on science and medicine, particularly in the fields of radioactivity and cancer treatment.

Discovery of Radium
On December 26, 1898, Marie and Pierre Curie announced the discovery of a new radioactive element, which they named radium.
Marie Curie, generally considered to be the more gifted member of the husband and wife team, was born as Marya Sklodowska on November 7, 1867, in Warsaw, Poland. She demonstrated an exceptional aptitude for physics from a very young age and left Poland in 1891 to pursue advanced studies at the prestigious Sorbonne in Paris, France. There she met Pierre Curie, a physics professor, and married him in 1895. The two became especially interested in the properties of pitchblende, a uranium ore, after Marie discovered that samples of the ore were actually more radioactive than pure uranium itself. This suggested the possible presence of other, unknown elements that were far more radioactive.
The Curies isolated radium, but although they announced its discovery on December 26, 1898, it took them until March 1902 to isolate enough of this highly radioactive substance to confirm its existence. They were also able to isolate another new element, which was named polonium after Marie's home country of Poland. This confirmation earned the Curies the Nobel Prize for Physics in 1903, and Marie became the first women ever to receive a Nobel Prize. Her work in separating radium and polonium from pitchblende also earned her the Prize for chemistry in 1911. She died on July 4, 1934, in Sallanches, France, from leukemia that may well have been contracted from her years of close contact with radioactive substances.
