Marie Curie was born November 7, 1867 in Poland and died on July 4, 1934. Her co-discovery with her husband Pierre Curie of the radioactive elements radium and polonium(钋) represents one of the best known stories in modern science for which they were recognized in 1901 with the Nobel Prize in Physics. In 1911, Marie Curie was honored with a second Nobel Prize, this time in chemistry, to honor her for successfully isolating pure radium and determining radium's atomic weight.
As a child, Marie Curie amazed people with her great memory. She learned to read when she was only four years old. Her father was a professor of science and the instruments that he kept in a glass case fascinated Marie. She dreamed of becoming a scientist, but that would not be easy. Her family became very poor, and at the age of 18, Marie became a governess. She helped pay for her sister to study in Paris. Later, her sister helped Marie with her education. In 1891, Marie attended the Sorbonne University in Paris where she met and married Pierre Curie, a well-known physicist.
Marie Curie contributed greatly to our understanding of radioactivity and the effects of x-rays. She received two Nobel prizes for her brilliant work, but died of leukemia(白血病), caused by her repeated exposure to radioactive material.
