Maria Skłodowska-Curie coined a term of "radioactivity" that was the subject of the first Nobel Prize she won with her husband and Henri Becquerel.

After her husband death, Maria Skłodowska-Curie received a second prize in 1911 in chemistry for discovering the new elements polonium (Po) and radium (Ra), isolating pure radium and studying the chemical properties of radioactive elements. Her discoveries have become a breakthrough in the fight against cancer. During World War I she developed mobile radiography units to provide X-ray services to field hospitals.

She was a French citizen but she used both surnames and never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland. Moreover, she named the first chemical element she discovered polonium, after her native country.

She became one of the most important figures among the scientists. A photograph below presents probably the most formidable gathering of scientists in history - the first Solvay Conference, in 1911, Brussels, Belgium. Most of the scientists in the picture are Nobel laureates.

The Curie legacy is glorified to this day, and without the medical and chemical discoveries of the Nobel Prize-winning couple, many areas of science would not have developed to the state we are used to today. 

The property in Paris that was frequently visited by Maria Skłodowsa-Curie has been recently bought by Polish billionaire Dominika Kulczyk. She is going to create a charitable foundation called “House of Sisterhood” where exceptional women from all over Europe will have a chance to broaden their knowledge and perhaps follow in Curie’s footsteps and become new Nobelists.
