38 Interesting Facts About Marie Curie

Marie Curie, best known for the development of the theory of radioactivity, was a Polish and naturalized-French physicist and chemist. With these 38 interesting facts about Marie Curie, let’s learn more about her inventions, personal life, contributions to science and society and Nobel Prizes.

Facts about Marie Curie’s childhood, family and education 

1. Born Maria Sklodowska, Marie Curie, as we all know her today, was the fifth child of her teacher parents.

2. Due to the strained financial condition of her family during childhood,, she worked as a governess at her father’s relative’s house. There, she fell in love with the family’s son, Kazimierz Zorawski, and wanted to marry him. However, the boy’s family denied the marriage, citing the bad financial conditions of the Curie family.

3. In 1883, when Maria graduated from high-school, she earned a gold medal for her academic excellence.

4. In 1891, Maria migrated to Paris, France. There, she began to pursue her education at the University of Paris, making ends meet by working part-time. It is also notable here that sometimes because of the lack of finances to buy proper meals, she fainted from hunger. However, determined to learn, she did not discontinue her studies.

5. Here, Maria adopted the French spelling of her name “Marie.”

Facts about Marie and Pierre Curie

6. Marie Curie was introduced to Pierre Curie, who later became her husband, by a Polish physicist. At the time of their meeting, Marie Curie was in need of a laboratory, and the Polish physicist was of the opinion that Pierre could afford to arrange a laboratory for Marie to continue her mission.

7. When the duo (Marie and Pierre) started working together, they developed feelings for each other. Marie refused Pierre’s initial proposal of marriage because Marie wanted to go back to her motherland and work there. Pierre declared that he was ready to move to Poland with Marie and teach French for the sake of living. Eventually, they got married on July 26th, 1895 in Sceaux.

8. In 1898, Henry Becquerel discovered the “strange activity” properties of Uranium. At that time, Marie decided to investigate. During her studies, she learned that thorium also possessed such activity.

9. Pierre, intrigued and interested in the work Marie was doing, joined his spouse in mid-1898.

Discovery of Polonium and Radium

10. Discovery of Polonium: when Marie Curie realized the fact that the mineral pitchblende, which contained Uranium, was a great deal more radioactive than Uranium alone, she formed the opinion that there was some other element that caused the high level of radioactivity. The Curie duo started working on the mineral and finally extracted a black powder that was 330 times more radioactive than Uranium. They named the element Polonium, after Poland, Marie Curie’s home country.

11. Discovery of Radium: once Polonium was discovered, the duo analyzed the remaining liquid for radioactivity. They were once again amazed by the high level of radioactivity still available through the liquid. They soon started working on the compound to find the other element that caused the radioactivity. Their grueling labor yielded great results: they found radium.

12. Marie applied for a position at the Polish University of Krakow. However, being a woman, she was denied.

Regarding radium, Marie Curie said: “We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.”

About the subpar laboratory, effect of radioactivity on the couple’s health, Pierre’s death and Einstein’s letter to Marie

13. The couple did not have a well-equipped and well-structured laboratory. They used a converted shed next to the School of Physics and Chemistry. The shed was poorly ventilated and was not even waterproof. German scientist, Wilhelm Ostwald, described their workplace as, “a cross between a stable and a potato shed.” Notable here is the determination and the interest of the Curies to continue their work in the field of radioactivity, despite the troubles and shortcomings.

14. Marie Curie kept a sample of radium next to her bed as a night light.

15. The Curies died unaware of the fact that the radioactive elements were damaging to their health all the time they handled and worked on them. Even the notes that they had compiled at that time and the papers that they had written are radioactively contaminated to this day. They are preserved in lead-lined boxes and when they are referenced, they are handled with the utmost care.

16. In 1906, Pierre Curie died of a road accident. This incident shattered Marie Curie; however, her firm resolution to continue her work in physics and chemistry kept her going.

17. After the death of her husband, she had a brief affair with one of Pierre Curie’s students, who was five years younger than her.

18. When the news of this affair broke out, Marie faced a great deal of criticism from the public. She started hiding from public view and lived in a friend’s house with her daughter. This incident weakened her and she lost confidence in her ability to fight back.

19. In the prestigious invite-only Slovary Conference in 1911, Marie Curie was the only woman invitee out of its 24 members. Einstein was also one of the attendees of the conference.

20. Albert Einstein, who met Marie at the Slovary Conference in 1911, wrote her a letter encouraging her during her tough time with the public. Here is a copy of the letter by Albert Einstein.
