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
Nobel Prize controversies Millikan might have won in 1920 but for Felix Ehrenhaft's incorrect claim to have measured a smaller charge. Some controversy, however, still seems to linger over Millikan's oil-drop procedure and experimental interpretation, over whether Millikan manipulated his data in the 1913 scientific paper measuring the electron charge. Allegedly, he did not report all his observations. The 1903 prize went to Henri Becquerel (along with Pierre and Marie Curie) "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity". However, critics alleged that Becquerel merely rediscovered a phenomenon first noticed and investigated decades earlier by the
