Marie And Pierre Curie example essay topic
Marie then studied pitchblende, a uranic mineral in which she measured a much more intense activity than is present in uranium alone. She deduced that there were other substances besides uranium that were very radioactive, such as polonium and radium, which she discovered in 1898. In their experiments, Pierre observed the properties of the radiation while Marie, for her part, purified the radioactive elements. Both shared the same, uncanny tenacity, which was all the more admirable given their deplorable living conditions. Their laboratory was nothing more than a miserable hangar, where in winter the temperature dropped to around six degrees.
One chemist commented that 'it looked more like a stable or a potato cellar'. And yet, Marie admitted that 'one of our pleasures was to enter our workshop at night; then, all around us, we would see the luminous silhouettes of the beakers and capsules that contained our products'. Despite their difficulty at obtaining any advances or loans, Marie and Pierre Curie refused to file a patent application that would have secured them financially; in their eyes, enabling any scientist, French or foreign, to find applications for radioactivity took priority. Pierre tested radium on his skin.
It caused a burn, and then a wound: its effect on man was thus proven. Soon radium was being used to treat malign tumours: Curie therapy was born. In 1903, Marie defended her thesis. Together with Becquerel, the Curies were awarded the Nobel Prize for Physics for their discovery of natural radioactivity. Their happiness was short lived. In 1906, Pierre, weakened by radiation and overworked, was run over by a car.
Marie was forced to continue alone. She took charge of educating her two children; she took up the position which her husband had finally obtained at the Sorbonne, and thus became the first woman to be appointed professor there. She also had to fight the prejudices of her day: hatred of foreigners and sexism which, in 1911, prevented her from entering the Academy of Science. And yet, soon after, she was honoured with a Nobel Prize for Chemistry for determining the atomic weight of radium. But her real joy was 'easing human suffering'. The founding of the Radium Institute by the University of Paris and the Pasteur Institute in 1914 would enable her to fulfil her humanitarian wish..
