Ir鋝e Curie-Joliot(R) and Bertrand Russell (L). Ir鋝e Curie, born in Paris, September 12, 1897, was the daughter of Pierre and Marie Curie, and since 1926 the wife of Fr嶮廨ic Joliot. After having started her studies at the Faculty of Science in Paris, she served as a nurse radiographer during the First World War. She became Doctor of Science in 1925, having prepared a thesis on the alpha rays of polonium. Either alone or in collaboration with her husband, she did important work on natural and artificial radioactivity, transmutation of elements, and nuclear physics; she shared the Nobel Prize in Chemistry for 1935 with him, in recognition of their synthesis of new radioactive elements, which work has been summarized in their joint paper Production artificielle d'幨幦ents radioactifs. Preuve chimique de la transmutation des 幨幦ents (1934). Bertrand Arthur William Russell (b.1872 - d.1970) was a British philosopher, logician, essayist, and social critic, best known for his work in mathematical logic and analytic philosophy. His most influential contributions include his defense of logicism (the view that mathematics is in some important sense reducible to logic), and his theories of definite descriptions and logical atomism. Along with G.E. Moore, Russell is generally recognized as one of the founders of analytic philosophy. Along with Kurt G鐰el, he is also regularly credited with being one of the two most important logicians of the twentieth century.
