Stefania Maracineanu 140th Birthday
The design honors the scientist’s work on polonium, a chemical element discovered by Marie Curie.
Stephanie Mărăcineanu was born on June 18, 1882, in Bucharest, Romania, and enrolled in her hometown’s university in 1907. She became a teacher three years after graduating with a degree in physical and chemical science.

Mărăcineanu obtained a job at the Central School for Girls in Bucharest, which she had attended as a youngster, after working around Romania in 1915.
Despite the fact that Mărăcineanu’s doctoral dissertation stated that she had discovered the discovery more than a decade prior, Joliot-Curie did not recognise her work.
It was officially recognized by Romania’s Academy of Sciences in 1936, but her contribution was overlooked by the rest of the world’s scientific community.
