Pierre Curie (15 May 1859 – 19 April 1906) was a French physicist, a pioneer in crystallography, magnetism, piezoelectricity and radioactivity. In 1903 he received the Nobel Prize in Physics with his wife, Marie Salomea Skłodowska-Curie, and Henri Becquerel, "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel".
Marie Skłodowska-Curie (1867–1934) Born in Poland, she moved to France in 1891. She is the first woman to receive a Nobel Prize (physics 1903). She received a second Nobel Prize in 1911, this time in chemistry. Marie and Pierre Curie isolated polonium and radium. She actively promoted the use of radium for medical purposes throughout her life.
Irène Joliot-Curie (1897 – 1956) was a French scientist, the daughter of Marie and Pierre Curie. She was awarded the Nobel Prize for chemistry in 1935 for the discovery of artificial radioactivity. This made the Curies the family with the most Nobel laureates to date. She died of leukemia from accumulated radiation exposure.
