# Marie Curie Maria Salomea Skłodowska-Curie (1867–1934) was a Polish-French physicist and chemist who conducted pioneering research on radioactivity — a term she coined. She was the first woman to win a Nobel Prize, the first person to win Nobel Prizes in two different sciences (Physics in 1903, Chemistry in 1911), and remains the only person to have achieved this distinction. Her discoveries of polonium and radium laid the groundwork for nuclear physics, cancer treatment, and our fundamental understanding of atomic structure. ## Scientific Breakthroughs Curie's doctoral research, begun in a converted shed at the École de Physique in Paris, investigated the mysterious rays emitted by uranium salts first observed by Henri Becquerel. Working systematically through every known element, she discovered that thorium also emitted rays, and that the intensity of radiation was proportional to the amount of element present — proof that radioactivity was an atomic property, not a chemical one. This was a conceptual revolution. With her husband Pierre Curie, she then isolated two new radioactive elements: polonium (named for her native Poland, then partitioned and under occupation) and radium. The process required processing tons of pitchblende ore by hand in grueling physical labor. The 1903 Nobel Prize in Physics was initially to be awarded only to Pierre and Becquerel — it was Pierre who insisted Marie be included. ## Defying Institutional Barriers After Pierre's death in 1906, Marie succeeded him as professor at the Sorbonne — the first woman to hold a professorship there in its 650-year history. When she was nominated for the French Academy of Sciences in 1911, she lost by two votes after a campaign that attacked her as a foreigner and a woman. The same year, she won her second Nobel Prize. The French press subjected her to xenophobic and misogynistic attacks throughout her career. She was a Polish immigrant in France, a woman in a man's field, and eventually a widow who dared to have a personal life — all of which made her a target for the kind of reactionary cultural politics that remains depressingly familiar. ## Legacy and Relevance to the Right-Wing KB Curie's story is a case study in how institutional power structures resist transformative talent when it comes in the "wrong" package. The same dynamics play out today in right-wing attacks on immigration (she was an immigrant), women in STEM (she was systematically excluded from institutions), and scientific research funding (her work was done in poverty-level conditions). Her research also connects to the nuclear dimension of defense tech — the atomic age she helped inaugurate became the foundation of the military-industrial complex, though she herself was a humanitarian who developed mobile X-ray units for battlefield medicine in World War I. --- ## See Also - [[Scientists]] - [[Vera Rubin]]
