Frédéric Joliot-Curie
Summary
Jean Frédéric Joliot-Curie (fʁedeʁik ʒɔljo kyʁi; ; 19 March 1900 – 14 August 1958) was a French physicist and husband of Irène Joliot-Curie, with whom he was jointly awarded the Nobel Prize in Chemistry in 1935 for their discovery of Induced radioactivity. They were the second ever married couple, after his wife's parents, to win the Nobel Prize, adding to the Curie family legacy of five Nobel Prizes. Joliot-Curie and his wife also founded the Orsay Faculty of Sciences, part of the Paris-Saclay University.
Born in Paris, France, Frédéric Joliot was a graduate of ESPCI Paris. In 1925 he became an assistant to Marie Curie, at the Radium Institute. He fell in love with her daughter Irène Curie, and soon after their marriage in 1926 they both changed their surnames to Joliot-Curie. At the insistence of Marie, Joliot-Curie obtained a second baccalauréat, a bachelor's degree, and a doctorate in science, doing his thesis on the electrochemistry of radio-elements.
While a lecturer at the Paris Faculty of Science, he collaborated with his wife on research on the structure of the atom, in particular on the projection, or recoil, of nuclei that had been struck by other particles, which was an essential step in the discovery of the neutron by James Chadwick in 1932. In 1935 they were awarded the Nobel Prize in Chemistry for their discovery of Induced radioactivity, resulting from the creation of short-lived radioisotopes by nuclear transmutation from the bombardment of stable nuclides such as boron, magnesium, and aluminium with alpha particles.
In 1937 he left the Radium Institute to become a professor at the Collège de France. In January 1939 he wrote a letter to his Soviet colleague Abram Ioffe, alerting him to the fact that German physicists had recently discovered nuclear fission of uranium bombarded by neutrons, releasing large amounts of energy. He went on to work on nuclear chain reactions and the requirements for the successful construction of a nuclear reactor that uses controlled nuclear fission to generate energy.
