Marie became the first woman to win a Nobel Prize and the only woman to win the award in two different fields -physics and chemistry. Her and her husband's (Pierre Curie) efforts led to the discovery of polonium & radium, and after Pierre's death, the further development of x-rays.

She was the youngest of 5 with 3 sisters and 1 brother. Both of her parents were educators who believed women should have an education just like men. At age 15, Maria graduated High school in top of her class. None of the colleges would except women so Maria and her sister Bronia left the country. When Maria was 17 she became a governess to help Bronia go to medical school in Paris while Maria studied on her own, waiting to join Bronia in getting a degree. When Registering for College Maria changed her name to Marie to sound more French. Though Marie was very smart, High school had not prepared her for college at Sorbonne. She lived in an apartment very close to college so she could get more study time and saved money by only drinking tea and eating bread.
Although she struggled at first, Marie graduated, top of her class and got a masters in physics in July 1893. The Woman's Education Advocates gave her a scholarship to get a degree in mathematics which she received in 1894.]]> 2016-10-25 00:58:29 UTC https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/132881093 hummingbirdcmt https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/133497255 One of Marie’s professors gave Marie a research grant for her to study the magnetic properties and chemical composition of steel. When arranging for lab space, she was introduced to a man named Pierre Curie. Pierre was an intelligent researcher and had invented several instruments for measuring magnetic fields and electricity. He got her a small place at the Municipal School of Industrial Physics and Chemistry where he worked. The two were married in the summer of 1895. 
 
Marie had been interested by the reports of Wilhelm Roentgen’s discovery of X-rays and by Henri Becquerel’s report of similar “rays” emitted from uranium ores. She decided to use Pierre’s instruments to measure the faint electrical currents she detected in air that had been bombarded with uranium rays. Her studies showed that the effects of the rays were constant even when the uranium ore was treated in different ways. She confirmed Becquerel’s observation that greater amounts of uranium in an ore resulted in more intense rays. Then she stated a revolutionary hypothesis; Marie believed that the emission of these rays was an atomic property of uranium. If true, this would mean that the accepted view of the atom as the smallest possible fragment of matter was false.

In 1898, she brainstormed the term “radioactive” to describe materials that had this effect. Pierre was very interested in her research so he put his own work aside to work with her. Together, they found that two ores, chalcolite and pitchblende, were much more radioactive than pure uranium. Marie suspected that these ores might contain undiscovered radioactive elements.

Several tons of pitchblende were donated by the Austrian government, but the space Marie was as a lab was too small. So they moved their research to an old shed outside of the school. Processing the ore was exhausting work. New protocols for separating the pitchblende into its chemical components had to be devised. Marie often worked late at night stirring huge cauldrons with an iron rod nearly as tall as her.

Little by little, various components of the ore were tested. The Curies found that two of the chemical components, one containing mostly bismuth and another containing mostly barium, were strongly radioactive. In July 1898, the Curies published their conclusion: the bismuth compound contained a previously undiscovered radioactive element that they named polonium, after Marie's native country, Poland. By the end of that year they had isolated a second radioactive element they called radium, from radius, the Latin word for rays. In 1902, they announced success in extracting purified radium.

In June 1903, Marie was the first woman in Europe to earn a doctorate in physics. In November of that year the Curies, together with Henri Becquerel, were named winners of the Nobel Prize in Physics for their contributions to the understanding of atomic structure. The nominating committee objected to including a woman as a Nobel Laureate, but Pierre insisted that the original research was Marie’s. In 1911, after Pierre’s death, Marie was awarded a second Nobel Prize in Chemistry for her discovery of the elements polonium and radium]]> 2016-10-26 23:57:41 UTC https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/133498636 hummingbirdcmt https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/133499537 Marie continued to do research in radioactivity. When World War I broke out in 1914, she paused her studies and organized a fleet of portable X-ray machines for doctors on the front.

After the war, she worked hard to raise money for her Radium Institute, including a trip to the U.S. But by 1920, she was suffering from medical problems, likely due to her exposure to radioactive materials. On July 4, 1934, she died of aplastic anemia, a blood disease that is often caused by too much exposure to radiation.

Maries was buried next to Pierre, but in 1995, their remains were moved and interred in the Pantheon in Paris alongside France's greatest citizens.

The Curies received another honor in 1944 with the discovery of the 96th element on the Periodic Table of Elements, which was named curium. ]]> 2016-10-27 00:12:07 UTC https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/133499537 hummingbirdcmt https://padlet.com/hummingbirdcmt/l0foyc6i7tpf/wish/133500389 “Nothing in life is to be feared, it is only to be understood.

"Be less curious about people and more curious about ideas."

"One never notices what has been done; one can only see what remains to be done."

"There are sadistic scientists who hurry to hunt down errors instead of establishing the truth."
