Marie Curie
Her Life Story

Marie Sklodoska Curie was born in Warsaw on 7 November 1867. Daughter of an impoverished secondary-school teacher, she went through general education whilst also being taught some scientific facts by her father. During this time she also worked as a governess to help support her elder sister who studied in Paris. Warsaw was at this rime under Russian rule. Marie became involved in the student's revolutionary comity and eventually had to leave for Krakow, which was owned by Australia.

In 1891, Marie moved to Paris to continue her education at La Sorbonne. At this early stage, she was already entranced by chemistry and took several advanced scientific courses. There she met the Physics Professor Pierre Curie, renowned for his work on the piezoelectric effect, and the year after that they married. The discovery of X-rays by Wilhelm Roentgen and Henri Becquerel's discovery of radioactivity in 1896 inspired Marie to chose this new field as the subject of her thesis and her further research. She later persuaded her husband to join her in this field.

Marie Curie received her doctor of Science in 1903. She also achieved quite remarkable status within the faculty, first succeeding from her husband as Head of the Physics Laboratory and then, following his death in a streetcar accident in 1906, as Professor of General Physics, becoming the first woman to hold this post. She was also director of the Curie Laboratory of the University of Paris which was founded in 1914.

Marie Curie was the first ever person to receive 2 Nobel prizes. The first in Physics in 1903, along with her husband and Becquerel, for the discovery of radioactivity, and the second in 1911, in Chemistry this time, for the discovery of the radioactive elements polonium and radium.

Throughout her life she remained dedicated to science and its use for the well-being of all men. She contributed immensely to the installation of a radioactivity laboratory in her home town of Warsaw, even receiving a gift of $50,000 from President Hoover donated by the American Friends of Science.

During her busy life, she also found time to bring up her two daughters. The eldest, Irene, went on to become a Nobel prize winner also with her husband, Frederic Joliot. Both Marie and Irene eventually died of leukemia, caused by their overexposure to radioactive materials throughout their lives. Marie died at Savoy, France, on July 4 1934

Facts about Pierre and Marie Curie:

Pierre Curie was a French physicist who made many breakthrough discoveries in radioactivity, crystallography and magnetism.

Some of his contributions to science include: The Curie Point – a temperature level where ferromagnetic substances lost their ferromagnetic behavior, Curie’s Law – the effect of temperature on paramagnetism, demonstrating the electric potential of crystals when compressed, designing an extremely accurate torsion balance for measuring magnetic coefficients and his combined work on radiation, isolating polonium and radium with his wife Marie Curie.

Marie Curie

Marie Curie was a chemist and physicist famous for becoming the first person to be awarded two Nobel Prizes. She was brought up in Poland before eventually moving to France and obtaining French citizenship.

After French physicist Henri Becquerel first discovered a strange source of energy coming from uranium (radioactivity), Marie Curie decided that this would make a good field for research. With the help of her husband and his vital electrometer, she made numerous scientific discoveries including showing that radiation did indeed come from the atom itself rather than an interaction between molecules.

In 1911 Marie Curie was awarded another Nobel Prize, this time in Chemistry, for her discovery of radium and polonium and subsequent research.

In 1932 Marie Curie founded the ‘Radium Institute’ in Warsaw, Poland. The name was changed after World War II to the ‘Maria Skłodowska-Curie Institute of Oncology’. The institute carries out specialized cancer research and treatment.

Famous Marie Curie quotes include: “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 ".

"One never notices what has been done; one can only see what remains to be done"”


Her works

In her initial research into radioactivity, Marie Curie identified the radioactive substances thorium and uranium. She then showed that the radioactivity of any substance was proportional to the amount of radioactive material present. Some samples being extremely radioactive, her husband Pierre and she set out to discover the source.

This initial research was carried out in rather poor conditions and both partners had to teach as well. However, in 1898, polonium was discovered, named thus after Marie's home country. This was the fruit of long and laborious tests of the ability of each isolated component to ionize air. This was followed later that year by Marie's discovery of traces of very radioactive radium. Methods for its separation from radioactive materials were developed and over four years, the Curies extracted 1 gram of pure radium from eight tons of raw ore. After Pierre's death in 1906, Marie succeeded in obtaining a pure specimen of radium which allowed its characterization and the careful study of its properties.

The therapeutic properties of radium were of particular interest. This led to the opening of radium institutes in France and Poland just before World War 1. Here, the further scientific and medical uses of this new species were explored. Marie did much to promote the use of radium to ease suffering. During the war, her daughter Irene and herself dedicated themselves to the treating of the wounded, developing a field system of portable X-ray machines.
