Which committee elected Marie Curie as a member in 1930?

Marie Curie was elected to the International Atomic Weights Committee in 1930.

The committee was part of the international effort to establish reliable, agreed values for the atomic weights of chemical elements. Its work mattered because scientists in different countries needed common numerical standards for chemical calculations, laboratory measurements, and periodic tables.

Curie’s appointment reflected the breadth of her scientific authority. She had won the 1903 Nobel Prize in Physics for work on radioactivity and the 1911 Nobel Prize in Chemistry for the discovery and study of polonium and radium. Her expertise in radioactive elements made her a natural participant in international discussions about atomic measurements.

The name can cause confusion because the organization changed names over time. It was called the International Committee on Atomic Weights in earlier periods and later became the IUPAC Commission on Atomic Weights, eventually gaining its modern name, Commission on Isotopic Abundances and Atomic Weights. The quiz’s wording identifies the committee by its 1930-era function.
