Marie Curie was born on November 7, 1867 in Warsaw, Poland. Her parents were both teachers. Her dad taught math and physics and her mom was headmistress at a girl's school. Marie was the youngest of five children.Growing up with her parents both being teachers Marie was taught to read and write early. She was a very smart child and did well in school. As Marie grew older her family came upon tough times. Poland was under the control of Russia at the time. People were not even allowed to read or write anything in the Polish language. Her father lost his job because he was in favor of Polish rule. Then, when Marie was ten, her oldest sister Zofia became sick and died from the disease typhus. Two years later her mother died from tuberculosis. This was a difficult time for the young Marie. After graduating from high school, Marie wanted to attend a university, but this wasn't something that young women did in Poland in the 1800s. The university was for men. However, there was a famous university in Paris, France called the Sorbonne that women could go to. Marie did not have the money to go there, but agreed to work to help pay for her sister Bronislawa to go to school in France, if she would help Marie after she graduated.It took six years, but, after Bronislawa graduated and became a doctor, Marie moved to France and entered the Sorbonne. During the six years Marie had read a lot of books on math and physics. She knew she wanted to become a scientist. Marie arrived in France in 1891. In order to fit in, she changed her name from Manya to Marie. Marie lived the life of a poor college student, but she loved every minute of it. She was learning so much. After three years she earned her degree in Physics. In 1894 Marie met Pierre Curie. Like Marie, he was a scientist and the two of them fell in love. They married a year later and soon had their first child, a daughter named Irene.Marie became fascinated by rays that were recently discovered by scientists Wilhelm Roentgen and Henri Becquerel. Roentgen discovered X-rays and Becquerel had found rays given off by an element called uranium. Marie began to do experiments. One day Marie was examining a material called pitchblende. She expected there to be a few rays from the uranium in pitchblende, but instead Marie found a lot of rays. She soon realized that there must be a new, undiscovered element in pitchblende. Marie and her husband spent many hours in the science lab investigating pitchblende and the new element. They eventually figured out that there were two new elements in pitchblende. They had discovered two new elements for the periodic table! Marie named one of the elements polonium after her homeland Poland. She named the other radium, because it gave off such strong rays. The Curies came up with the term "radioactivity" to describe elements that emitted strong rays. In 1903, the Nobel Prize in Physics was awarded to Marie and Pierre Curie as well as Henri Becquerel for their work in radiation. Marie became the first woman to be awarded the prize.In 1911 Marie won the Nobel Prize in Chemistry for discovering the two elements, polonium and radium. She was the first person to be awarded two Nobel Prizes. Marie became very famous. Scientists came from around the world to study radioactivity with Marie. Soon doctors found that radiology could help with curing cancer. When World War I started Marie learned that doctors could use X-rays to help determine what was wrong with an injured soldier. However, there weren't enough X-ray machines for every hospital to have one. She came up with the idea that the X-ray machines could move from hospital to hospital in a truck. Marie even helped to train people to run the machines. The trucks became known as petites Curies, meaning "little Curies" and are thought to have helped over 1 million soldiers during the war.Marie died on July 4, 1934. She died from overexposure to radiation, both from her experiments and from her work with X-ray machines. Today there are lots of safety measures to keep scientists from getting overexposed to the rays.
