Prizes, a lost election and no patent

Marie Curie won the Chemistry Nobel Prize in 1911, the same year she failed to gain a seat in the French Academy of Sciences. International honour and rejection at home could belong to one year. Neither event changed the date on which polonium and radium had been announced. Her work had continued through a major loss. Pierre died in a street accident in Paris on 19 April 1906. The University of Paris offered Marie the teaching position associated with his chair, and she took up his work there. Several accounts call her its first woman professor. Accounts distinguish her teaching in his place in 1906 from her later formal appointment to the full chair. The important point is that her university work continued after his death. In 1910, Marie and André Debierne prepared radium in metallic form. That was another stage of the chemical work. The Curies had announced radium in December 1898; a later pure-metal preparation did not erase that announcement. The discovery year, a later laboratory achievement and an award year answer different questions. On 23 January 1911, Édouard Branly won the place; Curie lost by one vote on the first ballot and by two on the second. The American Institute of Physics describes hostile coverage directed at Marie’s foreign background during the election. Such coverage is evidence about the contest for recognition, rather than evidence against the existence of radium. The Nobel Chemistry citation recognised the discoveries of polonium and radium, the isolation of radium, and study of its nature and compounds. The earlier Physics prize in 1903 had recognised Becquerel’s discovery and the Curies’ research on radiation. Reading the citations separately shows that the awards did not simply record identical events on different dates. The Curies also published their methods for isolating radium without taking out patents. The American Institute of Physics describes this publication and the developing radium industry. They did not gain the commercial fortune a successful patent might suggest. An unpatented process could circulate, while laboratories still needed equipment, material and money. What kind of recognition followed the work? Teaching, membership elections, prizes and commercial reward were separate paths. The lost election is a useful twist in a story usually told through medals. A map reconstructed for 1900 can place the earlier discoveries in their political setting, but cannot tell us how any Academy member voted in 1911 or how the Nobel committee decided.
