Most people know Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. (16) However, few people know that she was also the mother of a Nobel Prize winner.
    Irene Curie was born on September 12, 1897. At the age of 10, Irene’s talents and interest in mathematics were apparent. Irene entered Sevigne University in October, 1914, to prepare for her degree in mathematics and physics. When World War I began, she left Sevigne University to help her mother, who was using X-ray facilities to help save the lives of wounded soldiers. (17) Irene continued this work by developing X-ray facilities for military hospitals in France and Belgium. After the war she received a Military Medal for her work. In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot visited the Institute where he met Marie Curie. Frederic became one of her assistants and Irene taught him the techniques required to work with radioactivity. Irene and Frederic soon fell in love and got married on October 29, 1926. Their daughter was born in 1927 and their son in 1932.
    Like her mother, Irene combined family with career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, Frederic, in 1935, for producing new radioactive elements. (18) Unfortunately, also like her mother, she developed blood cancer because of her exposure to radiation. Irene Joliot-Curie died on March 17, 1956.
