Ir癡ne Joliot-Curie (September 12, 1897 - March 17, 1956) was a French scientist, the daughter of Marie Sklodowska-Curie and Pierre Curie. Jean Fr矇d矇ric Joliot-Curie (March 19, 1900 - August 14, 1958) was a French physicist. In 1925 he became an assistant to Marie Curie, at the Radium Institute. He fell in love with her daughter Ir癡ne Curie, and soon after their marriage in 1926 they changed their surnames to Joliot-Curie. In 1934 they created radioactive nitrogen from boron and then radioactive isotopes of phosphorus from aluminum and silicon from magnesium. They were awarded the Nobel Prize for chemistry in 1935 for their discovery of artificial radioactivity. In 1945, he became France's first High Commissioner for Atomic Energy. In 1948 he oversaw the construction of the first French atomic reactor. Both he and Ir癡ne died of conditions caused by their long exposure to radioactivity. Ir癡ne died in 1956 at the age of 58. He died in 1958 at the age of 58.
