The Warsaw Uprising of 1794 was an armed Polish insurrection by the Warsaw's populace early in the Kościuszko Uprising. Supported by the Polish Army, it aimed to throw off Russian control of the Polish capital. It began on 17 April 1794, soon after Tadeusz Kościuszko's victory at Racławice. A National Militia led by shoemaker Jan Kiliński, armed with rifles and sabers from the Warsaw Arsenal, inflicted heavy losses on the more numerous and better equipped, but surprised enemy garrison. Apart from the militia, the most famous units to take part in the liberation of Warsaw were formed of Poles who had been conscripted into the Russian service. Within hours, the fighting had spread from a single street on the western outskirts of Warsaw's Old Town to the entire city. Part of the Russian garrison was able to retreat under the cover of Prussian cavalry, but most were trapped inside the city. Isolated Russian forces resisted in several areas for two more days.
Marie Curie (1867–1934) was a Polish-French physicist and chemist. Born Maria Skłodowska in Warsaw, she studied at the clandestine Floating University and began her practical scientific training in the same city. In 1891, she followed her older sister to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work, becoming the first female professor at the University of Paris (La Sorbonne). Her achievements included a theory of radioactivity (a term that she coined), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium (which she named for her native country) and radium. Under her direction, the world's first studies were conducted into the treatment of neoplasms, using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she established the first military field radiological centres. She was the first woman to win a Nobel Prize (in Physics, shared with her husband, Pierre Curie, and with her doctoral advisor, Henri Becquerel, in 1903), the only woman to win it in two fields (the other being Chemistry, in 1911), and the only person to win in multiple sciences. Curie died in 1934 of aplastic anemia brought on by years of her exposure to radiation.
