OnThisDay in 1903, Marie Skłodowska Curie defends her doctoral thesis on radioactive substances at Université de la Sorbonne in Paris – becoming the first woman in France to receive a doctoral degree.
The examination committee expressed the opinion that Curie’s findings, including the determination of radium’s atomic weight, represented the greatest scientific contribution ever made in a doctoral thesis.
In the committee’s three members were two future Nobel Laureates: Gabriel Lippmann (Physics 1908) and Henri Moissan, (Chemistry 1906).
Thesis cover: Recherches sur les substances radioactives (Research on Radioactive Substances), 1903.
