Paris in the Belle Époque studying the fluorescence of uranium salts, discovered radioactivity in 1896, and in 1903 was awarded the Nobel Prize in physics for his discovery. Pierre Curie (1859-1906) and Marie Curie (1867-1934) jointly carried on Becquerel's work, discovering radium and polonium (1898). They jointly received the Nobel Prize for physics in 1903. Marie Curie became the first female professor at the University of Paris and won the Nobel Prize for chemistry in 1911. She was the first woman to be buried in the Panthéon. The neon light was used for the first time in Paris on 3 December 1910 in the Grand
Marie Curie theory of "radioactivity" (a term that she coined), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world's first studies into the treatment of neoplasms were conducted using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she developed mobile radiography units to provide X-ray services to field hospitals. While a French citizen, Marie Skłodowska Curie, who used both surnames, never lost her sense of Polish identity. She taught her daughters the Polish language and took
