Marie Skłodowska was born in Warsaw, Poland, to a family of teachers who believed strongly in education. She moved to Paris to continue her studies and there met Pierre Curie, who became both her husband and colleague in the field of radioactivity. The couple later shared the 1903 Nobel Prize in Physics. Marie was widowed in 1906, but continued the couple’s work and went on to become the first person ever to be awarded two Nobel Prizes. During World War I, Curie organized mobile X-ray teams. The Curies’ daughter, Irene, was also jointly awarded the Nobel Prize in Chemistry alongside her husband, Frederic Joliot.
The 1896 discovery of radioactivity by Henri Becquerel inspired Marie and Pierre Curie to further investigate this phenomenon. They examined many substances and minerals for signs of radioactivity. They found that the mineral pitchblende was more radioactive than uranium and concluded that it must contain other radioactive substances. From it they managed to extract two previously unknown elements, polonium and radium, both more radioactive than uranium.
“We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.”
