128 years ago today, September 12, 1897 (August 16, 1897 in the lunar calendar), French scientist Iren Joliot Curie was born. Irene Jorio Curie (eldest daughter of Madame Curie) and Frédéric Jorio-Curie Irene Jorio Curie (1897 - 1956)(Foreign women usually take their husband's surname after marriage, and in order to commemorate the great surname of Curie, the couple adopted the method of combining the couple's surname.) Born in Paris on September 12, 1897, her father Pierre Curie and her mother Marie Curie are both famous scientists. She is the eldest daughter of the Curie couple, her original name is Irene Curie. Although Iren only went to school when she was 12 years old, she received science education from her mother since she was a child. Marie Curie formed a collaborative group with her colleagues and friends to share the responsibility of educating their own children in the natural sciences. Among them, Marie Curie taught physics, Pauli and Langevin taught mathematics, and J. Perrin taught chemistry. In 1909, Irun entered the Secondary School of Severine, obtained a bachelor's degree before the outbreak of World War I, and then entered the University of Paris. After the outbreak of World War I, Irun served in the army as a nurse. At first, she assisted her mother with her work, and a few months before the liberation of Paris, Irun and her children were arranged to go to Switzerland for her safety. In 1932, he collaborated with her husband Jorio Curie (foreign women usually take their husband's surname after marriage, and the couple adopted the method of combining the husband and wife's surname to commemorate the great surname of Curie) to discover a kind of penetrating radiation that was later identified as neutrons; in 1934, artificial radioactive materials were discovered and the phenomenon of fission was studied. The couple shared the Nobel Prize in Chemistry in 1935. In 1946, Irun became director of the Radium Institute, and from 1946 to 1950 she also served as a director of the French Atomic Energy Commission. In 1947, he was elected as a correspondent academician of the Soviet Academy of Sciences. The couple also led the construction of France's first nuclear reactor in 1948. Due to lack of protection and long-term exposure to X-rays and gamma rays, Ilen's health was seriously damaged, causing her to suffer from acute leukemia and unfortunately died in Paris on March 17, 1956.
