LifeScience Moment: Marie and Pierre Curie isolated a new element that came to be called “radium.” "
On December 21, 1898, Marie and Pierre Curie published strong evidence that supported the existence of the
new element that came to be called “radium,” a landmark moment in chemistry and physics.
In the 1890's, the Curies were research workers at the School of Chemistry and Physics in Paris where
they began their pioneering work into invisible rays given off by uranium - a new phenomenon which had
recently been discovered by Professor Antoine-Henri Becquerel. He had shown that the rays were able to
pass through solid matter, fog and photographic film and caused air to conduct electricity.
In 1902 Marie eventually isolated radium (as radium chloride), determining its atomic weight as 225.93.
In 1903 Marie and Pierre were awarded the Nobel Prize for Physics jointly with Professor Becquerel for their
combined though separate work on radioactivity. In the same year, Marie passed her doctorate thesis in
