Marie Curie

Marie Curie (Maria Skłodowska-Curie, November 7 1867 – July 4 1934) was a Polish chemist and pioneer in the early field of radiology and a two-time Nobel laureate. She founded the Curie Institutes in Paris and in Warsaw.

Biography

Born in Warsaw, Poland, her first years were sorrowful ones, marked by the death of her sister and, four years later, her mother. She was notable for her diligent work ethic, neglecting even food and sleep to study. After graduating from high school, she suffered a mental breakdown for a year. Due to her gender, she was not allowed admission into any Russian or Polish universities so she worked as a governess for several years. Eventually, with the monetary assistance of her elder sister, she moved to Paris and studied chemistry and physics at the Sorbonne, where she became the first woman to teach.

At the Sorbonne she met and married another instructor, Pierre Curie. Together they studied radioactive materials, particularly the uranium ore pitchblende, which had the curious property of being more radioactive than the uranium extracted from it. By 1898 they deduced a logical explanation: that the pitchblende contained traces of some unknown radioactive component which was far more radioactive than uranium; thus on December 26th Marie Curie announced the existence of this new substance.

Over several years of unceasing labour they refined several tons of pitchblende, progressively concentrating the radioactive components, and eventually isolated initially the chloride salts (refining radium chloride on April 20, 1902) and then two new chemical elements. The first they named polonium after Marie's native country, and the other was named radium from its intense radioactivity.

Together with Pierre Curie and Henri Becquerel, she was awarded the Nobel Prize in Physics, 1903: "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel". She was the first woman to be awarded a Nobel Prize.

Eight years later, she received the Nobel Prize in Chemistry, 1911 "in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element". In an unusual move, Curie intentionally did not patent the radium isolation process, instead leaving it open so the scientific community could research unhindered.

She was the first person to win or share two Nobel Prizes. She is one of only two people who has been awarded a Nobel Prize in two different fields, the other being Linus Pauling.

After her husband's death, she had an affair with physicist Paul Langevin, a married man who had left his wife, which resulted in a press scandal. Despite her notoriety as an honored scientist working for France, the public's attitude to the scandal tended towards xenophobia—she was a foreigner, from an unknown land (Poland was still referred to as a geographical area, under the Russian Tsar), an area known to have a significant Jewish population (Marie was an atheist, raised a Catholic, but that didn't seem to matter). France at the time was still reeling from the effects of the Dreyfus affair, so the scandal's effect on the public was all the more acute. It is a strange coincidence that Paul Langevin's grandson Michel later married her granddaughter H鬨ne Langevin-Joliot.

During World War I, she pushed for the use of mobile radiography units for the treatment of wounded soldiers. These units were powered using tubes of radium emanation, a colorless, radioactive gas given off by radium, later to be identified as radon. Marie personally provided the tubes, milked from the radium she purified. Promptly after the war started, she cashed in her and her husband's gold Nobel Prize Medals for the war effort.

In 1921, she did a tour of the United States, where she was welcomed triumphantly, to raise funds for research on radium.

In her later years, she was disappointed by the myriad of physicians and makers of cosmetics who used radioactive material without precautions.

Her death near Sallanches, France in 1934 was from leukemia, almost certainly due to her massive exposure to radiation in her work.

Her eldest daughter, Ir讥 Joliot-Curie, won a Nobel Prize for Chemistry in 1935, the year after Marie Curie's death. Her youngest daughter, Eve Curie, wrote a biography on Curie after her mother's death.

In 1995, Madame Curie was the first woman laid to rest under the famous dome of The Panth鯮 in Paris on her own merits.

During a period of hyperinflation in the 1990s, her picture was on the Polish 20,000-zloty banknote. Her picture also appeared on the French 500 franc note and on stamps and coins.

There is a biographical film about Curie (of dubious accuracy). An extremely ahistorical Marie Curie appears as a character in the comedy Young Einstein by Yahoo Serious.

Element 96, Curium, symbol Cm was named in her and Pierre's honour.
