12 September is reserved to Irène Joliot-Curie
Irène Curie, born in Paris, September 12, 1897, was the daughter of Pierre and Marie Curie, and since 1926 the wife of Frédéric Joliot.
Irène Curie was a French scientist who was awarded the 1935 Nobel Prize for Chemistry – just like her mother, Marie Curie, in 1911. She received the distinction for the discovery of artificial radioactivity.
After completing her education at the Sorbonne, she continued studying at the Radium Institute, which had been built by her parents. Along with her husband, she discovered methods to create radioactive material cheaply and easily, for use in medical environments.
