Marie Curie but she refused. In 1922 she became a fellow of the French Academy of Medicine. She also travelled to other countries, appearing publicly and giving lectures in Belgium, Brazil, Spain, and Czechoslovakia. Led by Curie, the Institute produced four more Nobel Prize winners, including her daughter Irène Joliot-Curie and her son-in-law, Frédéric Joliot-Curie. Eventually it became one of the world's four major radioactivity-research laboratories, the others being the Cavendish Laboratory, with Ernest Rutherford; the Institute for Radium Research, Vienna, with Stefan Meyer; and the Kaiser Wilhelm Institute for Chemistry, with Otto Hahn and Lise Meitner. In August 1922 Marie Curie
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
