Who discovered the radioactive element radium?

 

                         Marie Curie and her husband Pierre began their research into radioactivity in 1895. They soon discovered the new element thorium, and in 1898 they discovered two other elements — polonium and radium. They received the Nobel Prize for physics for this work in 1903, although they shared the prize with Henri Becquerel, who researched the same subject. After her husband’s death, Marie continued her research, winning a second Nobel Prize before dying in 1934 of cancer caused by unprotected exposure to atomic radiation. A new element discovered in 1944 was named curium in her honour.
