Who alerted Pierre Curie that Marie had been omitted from the 1903 Nobel nomination?

Magnus Gösta Mittag-Leffler alerted Pierre Curie that Marie had been omitted from the 1903 Nobel nomination. The Swedish mathematician recognized that the initial proposal appeared to honor Henri Becquerel and Pierre Curie without adequately crediting Marie’s essential contribution.

Mittag-Leffler’s warning prompted Pierre to insist that Marie be considered alongside him. In a preserved letter dated August 6, 1903, Pierre wrote that if he were seriously being considered for the prize, he wished to be considered together with Madame Curie for their research on radioactive bodies. Her work had been central to the Curies’ investigations, including the painstaking study of uranium radiation and the discovery of polonium and radium.

The episode illustrates the gender barriers surrounding scientific recognition in the early Nobel era. Marie was ultimately included, and the 1903 Nobel Prize in Physics went to Becquerel and the Curies for research on radiation phenomena.

A common mix-up is to credit Henri Poincaré or Gabriel Lippmann, who were connected with the nomination discussions. Svante Arrhenius was also a major Swedish scientist, but he was not the person who warned Pierre about Marie’s omission.
