Marie Curie was a Polish-born physicist and chemist and one of the most famous scientists of her time. Together with her husband Pierre, she won the Nobel Prize in 1903, and another one in 1911.

Marie Sklodowska was born in Warsaw on 7 November 1867, the daughter of a teacher. In 1891, she went to Paris to study physics and maths at the Sorbonne where she met Pierre Curie, professor of the School of Physics. They married in 1895.

The Curies worked together studying radioactivity(放射性), building on the work of the German physicist Roentgen and the French physicist Becquerel. In July 1898, the Curies announced the discovery of polonium(钋). At the end of the year, they announced the discovery of another, radium(镭). The Curies, along with Becquerel, won the Nobel Prize for Physics in 1903.

Pierre’s life was cut short in 1906 when he was knocked down and killed by a carriage. Marie took over his teaching post, becoming the first woman to teach at the Sorbonne, and devoted (献身于) herself to continuing the work that they had begun together. She received a second Nobel Prize, for Chemistry, in 1911.

The Curies’ research was important in developing X-rays in surgery. During World WarⅠ, Marie helped fixed X-ray equipment, which she herself drove to the front lines. She helped train doctors for the International Red Cross.

Although she achieved much success, men scientists in France were still against Marie, and she never received any financial help from her work. By the late 1920s her health was beginning to become worse. She died on 4 July 1934 from her dangerous research. The Curies’ eldest daughter Irene was a scientist and winner of the Nobel Prize for Chemistry.
