Marie Curie 1867-1934.

Dr. Marie Curie is known to the world as the scientist who discovered radioactive metals i.e. Radium & Polonium.

Marie Curie was a Polish physicist and chemist who lived between 1867-1934. Together with her husband, Pierre, she discovered two new elements (radium and polonium, two radioactive elements that they extracted chemically from pitchblende ore) and studied the x-rays they emitted. She found that the harmful properties of x-rays were able to kill tumors. By the end of World War I, Marie Curie was probably the most famous woman in the world. She had made a conscious decision, however, not to patent methods of processing radium or its medical applications.

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 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 was a physicist and chemist best known for her work on radioactivity; however, she also discovered the elements polonium and radium. She was awarded two Nobel Prizes " one in physics which she won jointly with her husband and Henri Becquerel, and another in chemistry " and was the first person to win two Nobel Prizes. She is still one of only two (along with Linus Pauling) to accomplish that feat. Curie is responsible for establishing the theory of radioactivity, but unfortunately she unwittingly also discovered the fatal effect radioactivity can have on your health; she died on July 4, 1934, of aplastic anemia caused by radiation exposure.

In 1895, Wilhelm Roentgen discovered the existence of X-rays, though the mechanism behind their production was not yet understood. In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power. He demonstrated that this radiation, unlike phosphorescence, did not depend on an external source of energy but seemed to arise spontaneously from uranium itself. Influenced by these two important discoveries, Marie decided to look into uranium rays as a possible field of research for a thesis.

Curie died in 1934 at the sanatorium of Sancellemoz (Haute-Savoie) , France, due to a plastic anemia brought on by exposure to radiation including carrying test tubes of radium in her pockets during research and her World War I service in mobile X-ray units created by her.

LONG LIVE Marie Curie.

Madem curie got two noble prizes, madem curie family got 5 noble prizes. Madem curie-2, her husbend piere curie-1 in 1903 alog with his wife and another man. In 1906 piere curie died in road accident, madem curie daughter irene curie and her husbend got noble prize for artificial radioactivity.

She was awarded half of the Nobel Prize for Physics in 1903, for their study into the spontaneous radiation discovered by Becquerel, who was awarded the other half of the Prize. In 1911 she received a second Nobel Prize, this time in Chemistry, in recognition of her work in radioactivity.

Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. The color of pure radium is almost pure white, but it readily oxidizes on exposure to air, becoming black in color.

Mari cure was given loads of plutonium by the poland government and her research on this element lead to the discovery and radium where one night in one of her store room an abandoned box and plutonium was glowing and that led to the invention of radium.

Curie died in 1934 aged 66 at a sanatorium in sancellemoz france due to a plastic anemia brought onby exposure to radiation while carring test tubes of radiumin her pockets during reseach and in the course of her work at feild hospitals during world war 2.
