Marie Salomea Skłodowska Curie (7 November 1867 – 4 July 1934), was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. As the first of the Curie family legacy of five Nobel Prizes, she was the first woman to win a Nobel Prize, the first person and the only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two scientific fields. She was the first woman to become a professor at the University of Paris in 1906.
She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw’s clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. In 1895 she married the French physicist Pierre Curie, and she shared the 1903 Nobel Prize in Physics with him and with the physicist Henri Becquerel for their pioneering work developing the theory of “radioactivity”—a term she coined. In 1906 Pierre Curie died in a Paris street accident. Marie won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
Under her direction, the world’s first studies were conducted into the treatment of neoplasms by the use of radioactive isotopes. In 1920 she founded the Curie Institute in Paris, and in 1932 the Curie Institute in Warsaw; both remain major centres of medical research. During World War I she developed mobile radiography units to provide X-ray services to field hospitals. While a French citizen, Marie Skłodowska Curie, who used both surnames, 8] never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland. She named the first chemical element she discovered polonium, after her native country.
Marie Curie died in 1934, aged 66, at the Sancellemoz sanatorium in Passy (Haute-Savoie), France, of aplastic anemia from exposure to radiation in the course of her scientific research and in the course of her radiological work at field hospitals during World War I. In addition to her Nobel Prizes, she has received numerous other honours and tributes; in 1995 she became the first woman to be entombed on her own merits in Paris’ Panthéon, and Poland declared 2011 as the Year of Marie Curie during the International Year of Chemistry. She is the subject of numerous biographical works, where she is also known as Madame Curie.
Liberté, égalité, fraternité, French for “liberty, equality , fraternity “, is the national motto of France and the Republic of Haiti , and is an example of a tripartite motto . Although it finds its origins in the French Revolution , it was then only one motto among others and was not institutionalized until the Third Republic at the end of the 19th century. Debates concerning the compatibility and order of the three terms began at the same time as the Revolution.
France, officially the French Republic (French: République française), is a sovereign state comprising territory in western Europe and several overseas regions and territories . The European part of France, called Metropolitan France , extends from the Mediterranean Sea to the English Channel and the North Sea , and from the Rhine to the Atlantic Ocean . France spans 640,679 square kilometres (247,368 sq mi) and has a total population of 67 million. It is a unitary semi-presidential republic with the capital in Paris , the country’s largest city and main cultural and commercial centre. The Constitution of France establishes the state as secular and democratic, with its sovereignty derived from the people.
During the Iron Age , what is now Metropolitan France was inhabited by the Gauls , a Celtic people. The Gauls were conquered in 51 BC by the Roman Empire , which held Gaul until 486. The Gallo-Romans faced raids and migration from the Germanic Franks , who dominated the region for hundreds of years, eventually creating the medieval Kingdom of France . France emerged as a major European power in the Late Middle Ages , with its victory in the Hundred Years’ War (1337 to 1453) strengthening French state-building and paving the way for a future centralized absolute monarchy . During the Renaissance , France experienced a vast cultural development and established the beginning of a global colonial empire . The 16th century was dominated by religious civil wars between Catholics and Protestants (Huguenots).
France became Europe’s dominant cultural, political, and military power under Louis XIV . French philosophers played a key role in the Age of Enlightenment during the 18th century . In 1778, France became the first and the main ally of the new United States in the American Revolutionary War . In the late 18th century, the absolute monarchy was overthrown in the French Revolution . Among its legacies was the Declaration of the Rights of Man and of the Citizen , one of the earliest documents on human rights , which expresses the nation’s ideals to this day. France became one of modern history’s earliest republics until Napoleon took power and launched the First French Empire in 1804. Fighting against a complex set of coalitions during the Napoleonic Wars , he dominated European affairs for over a decade and had a long-lasting impact on Western culture. Following the collapse of the Empire, France endured a tumultuous succession of governments: the monarchy was restored , it was replaced in 1830 by a constitutional monarchy , then briefly by a Second Republic , and then by a Second Empire , until a more lasting French Third Republic was established in 1870. By the 1905 law , France adopted a strict form of secularism , called laïcité , which has become an important federative principle in the modern French society.
France reached its territorial height during the 19th and early 20th centuries, when it ultimately possessed the second-largest colonial empire in the world. In World War I , France was one of the main winners as part of the Triple Entente alliance fighting against the Central Powers . France was also one of the Allied Powers in World War II , but came under occupation by the Axis Powers in 1940. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War . The Fifth Republic , led by Charles de Gaulle , was formed in 1958 and remains to this day. Following World War II , most of the empire became decolonized .
Throughout its long history , France has been a leading global center of culture, making significant contributions to art , science , and philosophy . It hosts Europe’s third-largest number of cultural UNESCO World Heritage Sites (after Italy and Spain ) and receives around 83 million foreign tourists annually, the most of any country in the world. France remains a great power with significant cultural , economic , military , and political influence. It is a developed country with the world’s sixth-largest economy by nominal GDP and eight-largest by purchasing power parity . According to Credit Suisse, France is the fourth wealthiest nation in the world in terms of aggregate household wealth. It also possesses the world’s second-largest exclusive economic zone (EEZ), covering 11,035,000 square kilometres (4,261,000 sq mi).
French citizens enjoy a high standard of living , and the country performs well in international rankings of education , health care , life expectancy , civil liberties, and human development . France is a founding member of the United Nations , where it serves as one of the five permanent members of the UN Security Council . It is a member of the Group of 7 , North Atlantic Treaty Organization (NATO), Organisation for Economic Co-operation and Development (OECD), the World Trade Organization (WTO), and La Francophonie . France is a founding and leading member state of the European Union (EU).
