Who is Marie Curie?

Marie Curie was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and the only woman to win the Nobel prize twice, and the only person to win the Nobel Prize in two different scientific fields. She was also the first woman to become a professor at the University of Paris. Her achievements included the development of the theory of radioactivity, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Marie Curie died in 1934 from aplastic anemia, believed to be caused by exposure to radiation.

Which universities did Marie Curie attend?

Marie Curie, née Maria Sklodowska, attended two universities during her life.

She first attended the "Flying University", an underground educational organization that gave higher education to Polish women, as women were not legally allowed to attend college in Russian-occupied Poland at that time. This was not a traditional university, but it planted the seeds of academic learning for Marie.

For higher education, Marie moved to Paris, France in 1891 and enrolled at the Sorbonne, also known as the University of Paris. Here, she earned her higher degrees, including a Master's degree in Physics in 1893 and a degree in Mathematics in 1894. It was in Paris that she conducted the pioneering research on radioactivity that would earn her two Nobel Prizes.

How did Marie Curie die?

Marie Curie died on July 4, 1934, from aplastic anemia, a condition that impairs the body's ability to produce enough new blood cells. Her condition was thought to be a result of prolonged exposure to radiation over her lifetime. Although the harmful effects of radiation were not well-understood during her time, Curie carried radioactive isotopes in her pockets, conducted experiments without sufficient protective measures, and was exposed to X-rays from unshielded equipment while setting up France's first military radiology units during World War I.

Was Marie Curie contaminated by radiation?

Yes, Marie Curie was unknowingly exposed to high levels of radiation throughout her scientific career due to her extensive work with radioactive substances, particularly radium and polonium.

At the time, the harmful effects of radiation were not well understood. She would physically handle these dangerous substances with her bare hands, and her equipment was frequently contaminated. In fact, her notebooks from her experiments are still so radioactive that they are kept in lead-lined boxes and require protective clothing to handle, even today.

Long-term exposure to radiation is believed to have caused the aplastic anemia that ultimately led to her death in 1934. Exposure to high levels of radiation can damage the body's bone marrow, reducing its ability to produce new blood cells. This is what causes aplastic anemia.
