Biography

Marie Skłodowska-Curie (1867–1934) was a Polish-born physicist and chemist best known for her groundbreaking research on radioactivity. She was born in Warsaw, Poland, during a time when women had very few opportunities in education. Despite facing many obstacles, she excelled in science from a young age.

Since higher education for women was restricted in Poland, Marie moved to Paris in 1891 to study at the Sorbonne University. She earned degrees in physics and mathematics, becoming one of the top students in her class. In 1895, she married Pierre Curie, a French scientist, and together they initiated on groundbreaking research that changed the course of science forever.

Discovery of Radioactivity (1896–1898)

Before Marie Curie’s work, the concept of radiation was not well understood. In 1896, scientist Henri Becquerel discovered that uranium emitted mysterious energy, but he did not investigate further.

Marie Curie expanded on Becquerel’s findings and conducted experiments to measure how uranium affected the air around it. She realized that this energy was not dependent on external sources like light or heat—it was an natural property of the uranium itself.

 She named this phenomenon radioactivity—a completely new concept in science.

 Radioactivity was a natural property of atoms, not a chemical reaction. These discoveries laid the foundation for nuclear physics and modern radiation therapy used in cancer treatment.

Discovery of Polonium and Radium (1898)

Marie Curie suspected that uranium was not the only element with radioactive properties. While testing pitchblende (a mineral containing

uranium), she found that it was much more

radioactive than pure uranium itself. This meant another, unknown substance was present.

Through months of detailed chemical experiments,

Marie and Pierre Curie isolated two completely new elements:

Polonium and Radium

Interesting Facts About Marie Curie

 First Woman to Win a Nobel Prize – In 1903, Marie Curie won the Nobel Prize in Physics (shared with Pierre Curie and Henri Becquerel) for their work on radioactivity.  First Female Professor at the Sorbonne – After Pierre Curie’s tragic death in 1906, she took over his position and became the first female professor at the Sorbonne.  Refused to Patent Her Discoveries – Despite the enormous potential for financial gain, Marie Curie refused to patent her discoveries, believing that science should benefit humanity, not personal profit.

Marie’s notebooks and personal belongings, including her wedding ring, are still radioactive and are stored in lead-lined boxes.
