'Marie' was born Maria Sklodowska in Poland November 7, 1867, to parents who were both teachers. Her father taught math and physics, and her mother ran a boarding house/school until Maria was born. While never wealthy, her father found it hard to get a job when he supported the Polish rebellion to free them from Russian rule. Maria's mother died when Maria was only 10.
Her father brought home experiments for her and her siblings to try out, and taught them as his own students. When she finished her basic schooling, Maria found she was not allowed to attend college in Poland because she was a woman.
One option was the 'Flying University' or 'Floating University,' a sort of underground school for women to learn the same as men. She and her sister Bronislawa took courses there, and then decided that since a woman could study alongside men in Paris, that first Bronislawa would go while Maria supported her, and then Maria would go while her sister supported her. To earn money, Maria took jobs as a governess. In one home, while she took care of the younger children, there was a grown son named Kaczmeirz with whom she fell in love. However, his parents didn't approve of him marrying a penniless woman (meaning, her father was poor), and so sadly they had to break up. Ironically, her sister Bronislawa fell in love with another man also named Kaczmeirz and did marry him.

It wasn't until 1891 that Maria left Poland for France (at age 26)
to finish her college degree at The Sorbonne in Paris. She barely had enough to get by and almost starved in the process, but she persevered, being interested in the qualities of magnetism. She met Pierre Curie, a French man who taught physics there. They were married in 1895. She wanted to return to Poland to teach, and Pierre declared he loved her so much, he would stop what he was working on and move to Poland with her; but when she realized she wouldn't be allowed to teach, she decided to remain in Paris, and she became a French citizen, then going by 'Marie.' She and Pierre had two daughters, Eve and Irene.
In 1903, Marie became the first woman to win the Nobel Peace Prize for her study of radiation. That prize was shared with her husband Pierre and Henri Bequerel. Pierre died in 1906. He was run over by a horse and carriage. In 1911, Marie once again won a Nobel Prize for her work in chemistry. This made her the first person, and the only woman, to win twice. In her acceptance speech, she noted that she felt she shared the award with Pierre. As an adult, their daughter Irene would also study radioactivity and would also be awarded a Nobel Peace Prize.
From NobelPeacePrize.org, a description of what Marie studied:
Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie's home country, Poland).
The 'laboratory' Marie and Pierre used to study was nothing but a shed with bad ventilation. A proper lab wasn't built for them until 1906.
They were jointly awarded the Nobel Peace Prize for Physics in 1903, but declined to travel to Stockholm to accecpt it. The money from the prize helped fund their research going forward.
While another scientist, Roentgen, discovered X-rays, the Curies studied radium and discovered it could be used to create Xrays as well. It has some relation to phosphorescence, like in these fish:
During World War I, Marie Curie helped create and manage traveling X-ray trucks to help with the wounded. Initially, it was thought X-rays were completely harmless. While that is not true, and X-rays these days use a fraction of the substance that they used to, X-rays led to the development of radiation therapy to shrink tumors. Digital photography is also used now, for such applications as dental imaging. Without first knowing about X-rays, we would not have CT scans or MRIs to 'see' into the body to diagnose injuries and illnesses. The Curies' work also led to the concept of using sound waves to create images. One important use of Ultrasound is to diagnose and pinpoint heart disease.
Not dancing creatures, but a heart pumping.
While her work was recognized as very important, she still did not have the respect of her countrymen in France or in Poland. She was harshly criticized for an affair she had, and was 'accused' of being a Jewish terrorist, spy, and all manner of fabricated things, mostly because she was a woman. Marie died at age 66 of anemia due to such massive exposure to radiation: her books and personal items are placed in lead boxes and can only be handled if proper safety precautions are followed. However, her contributions to science and medicine will improve lives forever.
