Poland insists on including Marie Curie's maiden name on new euro banknotes, sparking controversy with France.

The dispute between Poland and France over Marie Curie's legacy has intensified with the European Central Bank's plans to include her image on the €20 note. Polish officials are demanding the inclusion of her maiden name, Skłodowska, arguing that its omission is a historical inaccuracy. The ECB is consulting various sources to decide on the correct form of the name, and supportive reactions in Poland underline the importance of national identity and recognition of Curie's contributions. Although the ECB has mentioned the full name on its website, the future design of the banknotes remains uncertain.
