Marie curie

Marie Sklodowska Curie (1867-1934) was a Polish and naturalized-French physicist and chemist. In 1906, Pierre was killed in a traffic accident. They became known as “petites Curies” for their famous creator.

• Decades of handling radioactive materials—the effects of which were poorly understood at the time—ultimately took a toll on Curie.

Since nobody had ever found it before, it could only be present in tiny quantities and seemed to be very radioactive. Curie never worked on the Manhattan Project, but her contributions to the study of radium and radiation were instrumental to the future development of the atomic bomb.

Early Years

Curie was born in Warsaw, Poland on November 7, 1867, which was then part of the Russian Empire.

Tony, you’re a jealous man. Further work convinced her the very large readings she was getting could not be caused by uranium alone – there was something else in the pitchblende. University education for women was not available in Russia at the time, so Curie left to pursue her degrees at the University of Paris in 1891.

"They deserve their honour. During this time they began to feel sick and physically exhausted; today we can attribute their ill health to the early symptoms of radiation sickness. Eventually, they extracted a black powder 330 times more radioactive than uranium, which they called polonium.

Polonium was a new chemical element, atomic number 84.

When the Curies investigated further, they found that the liquid left behind after they had extracted polonium was still extremely radioactive. Isolating pure samples of these elements was exhausting work for Marie; it took four years of back-breaking effort to extract 1 decigram of radium chloride from several tons of raw ore.
