The Nobel Prize in Chemistry 1935 was awarded jointly to Frédéric Joliot and Irène Joliot-Curie "in recognition of their synthesis of new radioactive elements".
 

On the 10th of December, 1911, Marie Sklodowska, a Polish chemist of world-wide reputation, wife of Professor Pierre Curie, was present at the solemn Swedish Nobel Prize ceremony to receive the Prize for Chemistry "in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element." The capital importance of these discoveries is generally recognized and two other Nobel Prizes in Chemistry have been awarded for discoveries in the field of radioactive substances, in 1908 to Lord Rutherford and in 1922 to Frederick Soddy.
