Marie Curie Isolates Radium Chloride
On April 20, 1902, Polish-French physicist and chemist Marie Curie, alongside her husband Pierre, successfully isolated one-tenth of a gram of pure radium chloride from the mineral pitchblende. This monumental achievement in their Paris laboratory came four years after their initial discovery of the elements radium and polonium, marking a crucial step in understanding radioactivity and laying the groundwork for its applications in medicine and science. Their groundbreaking work earned them a Nobel Prize in Physics in 1903.
