The discovery of radio and polonium and x-ray From Warsaw, where she was born in 1867, Marie Sklodowska had moved to Paris to attend the faculty of sciences. There he met Pierre Curie, scientist and teacher already known at the Sorbonne and married him in 1895. Preparing the thesis, supported by her husband, she deepened the study of radioactive minerals.
The Curies discovered that a mineral pitchblende, radiation emitted, and the cause attributed to the presence of an even unknown contents in the ore. How to separate? After four years of work, dealing with a ton of ore, they succeeded, by dint of chemical treatments to isolate the new element called radio, the radiation it emits. It was the most sensational discovery of the new century.
not patented extraction method: they wanted everyone to freely produce the radio for the good of humanity. In fact, it was discovered that the new element effectively fighting the most terrible enemy of mankind: the cancer. For this very important research, in 1903 the Curies and Becquerel were awarded the Nobel prize for physics. Three years later, Pierre Curie died hit by a car. Marie to bear the sorrow of love of her daughters, Irene and Eve.
fact, replaced her husband in teaching, continuing his research. At the same time, supervised the education of daughters and had the satisfaction to find Irene in his passion for physics. Even the new research continues alone after the death of her husband, were crowned with success and in 1910 succeeded in isolating the "radio metal". For these new merits, the following year, she was awarded the second Nobel Prize, this time for chemistry. In 1914, the outbreak of World War I suspended the teaching and research laboratory, radiology services to arrange for the army. Marie equipping cars with x-ray equipment, often personally escorted to the front, accompanied by his daughter Irene.
Mother and daughter are doing their utmost to alleviate the suffering caused by war. After the war, the Institute of Radio Paris, scientists from around the world flocked to devote himself to research, under the leadership of Madame Curie. The brave woman scientist was always a simple, modest, alienated from honors. In fact, twice refused the Legion of Honour, accepting only part of the International Committee of the League of Nations, of which he was elected vice president. But his place was the laboratory. One spring evening in 1935, left the lab, recommending that the gardener to care for the roses. And there came back. He died July 4: his death in the sanatorium Sancellemoz was due to the consequences of long and intense absorption of radiation of radioactive bodies. Irene and her husband continued research in that field. Helen, their daughter, he is entrusted with the physics, like the famous grandmother.
