Together, they were awarded the Nobel Prize for Physics in 1903, and she received another one, for Chemistry, in 1911.Her work with radioactive materials doomed her, however. She died of a blood disease in 1934.n 1911, after Pierreâs death, Marie was awarded a second Nobel Prize in Chemistry for her discovery of the elements polonium and radium. Later years. Marie continued to do research in radioactivity.
She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she established the first military field radiological centres. While a French citizen, Marie SkÅodowska Curie (she used both surnames) never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland.
