Antoine Lavoisier

(Redirected from Antoine Laurent Lavoisier)

Antoine-Laurent de Lavoisier (August 26, 1743 – May 8, 1794) was a French nobleman prominent in the histories of chemistry, finance, biology, and economics. He stated the first version of the Law of Conservation of Matter, recognized and named oxygen (1778), disproved the phlogiston theory, and helped to reform chemical nomenclature. Lavoisier is often referred to as the father of modern chemistry. He was also an investor and administrator of the Ferme Générale, a private tax collection company; chairman of the board of the Discount Bank (later the Banque de France); and a powerful member of a number of other aristocratic administrative councils. Due to his prominence in the pre-revolutionary government in France, he was beheaded at the height of the French Revolution.

Early life

Born to a wealthy family in Paris, Antoine Laurent Lavoisier inherited a large fortune when his mother died. He attended the College Mazarin from 1754 to 1761, studying chemistry, botany, astronomy, and mathematics. His first chemical publication appeared in 1764. In 1767 he worked on a geological survey of Alsace-Lorraine. He was elected a member of the French Academy of Sciences in 1768 for an essay on street lighting. In 1769 he worked on the first geological map of France. In 1771, he married 13-year-old Marie-Anne Pierette Paulze, who translated from English for him, illustrated his books, and assisted him in his research.

Contributions to chemistry

Beginning in 1775, he served in the Royal Gunpowder Administration, where his work led to improvements in the production of gunpowder and the use of agricultural chemistry by designing a new method for preparing saltpeter.

Some of Lavoisier's most important experiments examined the nature of combustion, or burning. Through these experiments, he demonstrated that burning is a process that involves the combination of a substance with oxygen. He also demonstrated the role of oxygen in metal rusting, as well as its role in animal and plant respiration: working with Pierre-Simon Laplace, Lavoisier conducted experiments that showed that respiration was essentially a slow combustion of organic material using inhaled oxygen. Lavoisier's explanation of combustion replaced the phlogiston theory, which postulates that materials release a substance called phlogiston when they burn.

He also discovered that the inflammable air of Henry Cavendish which he termed hydrogen (Greek for water-former), combined with oxygen to produce a dew, as Joseph Priestley had reported, which appeared to be water. Lavoisier's work was partly based on the work of Priestley (he corresponded with Priestley and fellow members of the Lunar Society). However, he tried to take credit for Priestley's discoveries. This tendency to use the results of others without acknowledgment, then draw conclusions is said to be characteristic of Lavoisier. In Sur la combustion en general (On Combustion in general), 1777 and Considérations Générales sur la Nature des Acides (General Consideration on the Nature of Acids), 1778), he demonstrated that the "air" responsible for combustion was also the source of acidity. In 1779, he named this part of the air oxygen (Greek for acid-former), and the other azote (Greek for no life). In Reflexions sur le Phlogistique, 1783, Lavoisier showed the phlogiston theory to be inconsistent.

Lavoisier's experiments were among the first truly quantitative chemical experiments ever performed; that is, he carefully weighed the reactants and products involved, a crucial step in the advancement of chemistry. He showed that, although matter changes its state in a chemical reaction, the quantity of matter is the same at the end as at the beginning of every chemical reaction. He burnt phosphorus and sulfur in air, and proved that the products weighed more than the original. Nevertheless, the weight gained was lost from the air. These experiments provided evidence for the law of the conservation of matter. Lavoisier also investigated the composition of water and air, which at the time were considered elements. He discovered the components of water were oxygen and hydrogen, and that air was a mixture of gases - primarily nitrogen and oxygen. With the French chemists Claude-Louis Berthollet, Antoine Fourcroy and Guyton de Morveau, Lavoisier devised a chemical nomenclature, or a system of names describing the structure of chemical compounds. He described it in Méthode de nomenclature chimique (Method of Chemical Nomenclature, 1787). Their system facilitated communication of discoveries between chemists of different backgrounds and is still largely in use today, including names such as sulfuric acid, sulfates, and sulfites.

His Traité Élémentaire de Chimie (Elementary Treatise of Chemistry, 1789, translated into English by Robert Kerr) is considered to be the first modern chemical textbook, and presented a unified view of new theories of chemistry, contained a clear statement of the Law of Conservation of Mass, and denied the existence of phlogiston. Also, Lavoisier clarified the concept of an element as a simple substance that could not be broken down by any known method of chemical analysis, and he devised a theory of the formation of chemical compounds from elements. In addition, it contained a list of elements, or substances that could not be broken down further, which included oxygen, nitrogen, hydrogen, phosphorus, mercury, zinc, and sulphur. It also forms the basis for the modern list of elements. His list, however, also included light and caloric, which he believed to be material substances. While many leading chemists of the time refused to believe Lavoisier's new revelations, the Elementary Treatise was written well enough to convince the younger generation.

Lavoisier's fundamental contributions to chemistry were a result of a conscious effort to fit all experiments into the framework of a single theory. He established the consistent use of chemical balance, used oxygen to overthrow the phlogiston theory, and developed a new system of chemical nomenclature which held that oxygen was an essential constituent of all acids (which later turned out to be erroneous). For the first time the modern notion of elements is laid out systematically; the three or four elements of classical chemistry gave way to the modern system, and Lavoisier worked out reactions in chemical equations that respect the conservation of mass (see, for example, the nitrogen cycle). His contributions are considered the most important in advancing the science of chemistry to the level of what had been achieved in physics and mathematics.

Law and politics

Of key significance in Lavoisier's life was his study of law. He received a law degree and was admitted to the bar, but never practiced as a lawyer. He did become interested in French politics, and as a result, he obtained a position as tax collector in the Ferme Générale, a tax farming company, at the age of 26, where he attempted to introduce reforms in the French monetary and taxation system. While in government work, he helped develop the metric system to secure uniformity of weights and measures throughout France.

Execution

As one of 28 French tax collectors and a powerful figure in the unpopular Ferme Générale, Lavoisier was branded a traitor during the Reign of Terror by revolutionists in 1794, and tried, convicted and guillotined all on one day in Paris, at the age of 51. Ironically, Lavoisier was one of the few liberals in his position. One of his actions that may have sealed his fate was a contretemps a few years earlier with the young Jean-Paul Marat, who subsequently became a leading revolutionary.

An appeal to spare his life was cut short by the judge: "The Republic has no need of geniuses [or, alternately, "scientists."]." His importance for science was expressed by the mathematician Joseph Louis Lagrange who lamented the beheading by saying: "It took them only an instant to cut off that head, but France may not produce another like it in a century."

One and a half years following his death, Lavoisier was exonerated by the French government. When his private belongings were delivered to his widow, a brief note was included reading "To the widow of Lavoisier, who was falsely convicted."

About a century after his death, a statue of Lavoisier was erected in Paris. It was later discovered that the sculptor had not actually copied Lavoisier's head for the statue, but used a spare head of the Marquis de Condorcet, the Secretary of the Academy of Sciences during Lavoisier's last years. Lack of money prevented alterations being made and, in any case, the French argued pragmatically that all men in wigs looked alike anyway. The statue was melted down during the Second World War and has never been replaced. Lavoisier's real memorial is chemistry itself.

Can a severed head think?

A story relates how Lavoisier arranged a final experiment at his death intended to determine whether and for how long a severed head remains conscious after decapitation. Supposedly, Lavoisier decided to blink as many times as possible, and had an assistant count the blinks, which numbered between 15 and 20. The story may be apocryphal. Standard biographies have never mentioned the incident, and some biologists have expressed skepticism that it would be possible. Empirical evidence on this point varies in reliability and is difficult to evaluate.[1]

Empirical evidence on this point varies in reliability and is difficult to evaluate.[1]. The crimson birthmark on the top of his bald head was often the source of much satire among critics and cartoonists. Standard biographies have never mentioned the incident, and some biologists have expressed skepticism that it would be possible. Gorbachev is the most famous person in modern times with visible naevus flammeus. The story may be apocryphal. Nevertheless, he maintains respect for the faiths of people of all religions, as evidenced by his leading role in the establishment of freedom of religion laws in the former Soviet Union. Supposedly, Lavoisier decided to blink as many times as possible, and had an assistant count the blinks, which numbered between 15 and 20. Baptized in the Russian Orthodox church as a child, Gorbachev is an atheist.

A story relates how Lavoisier arranged a final experiment at his death intended to determine whether and for how long a severed head remains conscious after decapitation. A journalist asked him, "would you like the Berlin Wall to be taken down?" Gorbachev replied very seriously, "Why not?". Lavoisier's real memorial is chemistry itself. In 1989, on an official visit to China during the demonstrations in Tiananmen Square, shortly before the imposition of martial law in Beijing, Gorbachev was asked for his opinion on the great wall of China: "It's a very beautiful work", he replied, "but there are already too many walls between people". The statue was melted down during the Second World War and has never been replaced. In 1987, Gorbachev acknowledged that his liberalizing policies of glasnost and perestroika owed a great deal to Alexander Dubček's "socialism with a human face." When asked what the difference was between the Prague Spring and his own reforms, Gorbachev replied, "Nineteen years.". Lack of money prevented alterations being made and, in any case, the French argued pragmatically that all men in wigs looked alike anyway. In the West, Gorbachev was colloquially known as 'Gorby', in part because of a perception that he was less austere than his predecessors.

It was later discovered that the sculptor had not actually copied Lavoisier's head for the statue, but used a spare head of the Marquis de Condorcet, the Secretary of the Academy of Sciences during Lavoisier's last years. He also received an honorary Doctorate from the University of Münster. About a century after his death, a statue of Lavoisier was erected in Paris. Bush. When his private belongings were delivered to his widow, a brief note was included reading "To the widow of Lavoisier, who was falsely convicted.". President George H.W. One and a half years following his death, Lavoisier was exonerated by the French government. In 2005, Gorbachev was awarded the Point Alpha Prize for promoting German reunification along with former German Chancellor Helmut Kohl and former U.S.

An appeal to spare his life was cut short by the judge: "The Republic has no need of geniuses [or, alternately, "scientists."]." His importance for science was expressed by the mathematician Joseph Louis Lagrange who lamented the beheading by saying: "It took them only an instant to cut off that head, but France may not produce another like it in a century.". Gorbachev, together with Boris Yeltsin, criticized Putin's actions as a step away from democracy. One of his actions that may have sealed his fate was a contretemps a few years earlier with the young Jean-Paul Marat, who subsequently became a leading revolutionary. In September 2004, following Chechen terrorist attacks across Russia, President Vladimir Putin launched an initiative to replace the election of regional governors with a system whereby they would be directly appointed by the President and approved by regional legislatures. Ironically, Lavoisier was one of the few liberals in his position. In June 2004, Gorbachev represented Russia at the funeral of Ronald Reagan. As one of 28 French tax collectors and a powerful figure in the unpopular Ferme Générale, Lavoisier was branded a traitor during the Reign of Terror by revolutionists in 1794, and tried, convicted and guillotined all on one day in Paris, at the age of 51. Gorbachev to Trademark his Forehead.

While in government work, he helped develop the metric system to secure uniformity of weights and measures throughout France. The company now no longer uses the trademark. He did become interested in French politics, and as a result, he obtained a position as tax collector in the Ferme Générale, a tax farming company, at the age of 26, where he attempted to introduce reforms in the French monetary and taxation system. In early 2004, Gorbachev moved to trademark his famous port wine birthmark, after a vodka company featured the mark on labels of one of their drinks to capitalize on its fame. He received a law degree and was admitted to the bar, but never practiced as a lawyer. He resigned as party leader in May 2004 over a disagreement with the party's chairman over the direction taken in the December 2003 election campaign. Of key significance in Lavoisier's life was his study of law. On November 26, 2001, Gorbachev also founded the Social Democratic Party of Russia—which is a union between several Russian social democrat parties.

His contributions are considered the most important in advancing the science of chemistry to the level of what had been achieved in physics and mathematics. In 1997, Gorbachev starred in a Pizza Hut commercial made for the USA to raise money for the Perestroika Archives. For the first time the modern notion of elements is laid out systematically; the three or four elements of classical chemistry gave way to the modern system, and Lavoisier worked out reactions in chemical equations that respect the conservation of mass (see, for example, the nitrogen cycle). In 1996, Gorbachev ran for re-election in Russia, but received only about 1 percent of the vote. He established the consistent use of chemical balance, used oxygen to overthrow the phlogiston theory, and developed a new system of chemical nomenclature which held that oxygen was an essential constituent of all acids (which later turned out to be erroneous). He also became a member of the Club of Rome. Lavoisier's fundamental contributions to chemistry were a result of a conscious effort to fit all experiments into the framework of a single theory. In 1993, he also founded Green Cross International, of which he was one of three major sponsors of the Earth Charter.

While many leading chemists of the time refused to believe Lavoisier's new revelations, the Elementary Treatise was written well enough to convince the younger generation. Gorbachev founded the Gorbachev Foundation in 1992. His list, however, also included light and caloric, which he believed to be material substances. Nevertheless, polls indicate that a majority of Russians are pleased with the result of the individual aims of perestroika, Gorbachev's chief legislative legacy. It also forms the basis for the modern list of elements. However in Russia, his reputation is very low because he is perceived to have brought about the collapse of the country and is held responsible for the misery that followed. In addition, it contained a list of elements, or substances that could not be broken down further, which included oxygen, nitrogen, hydrogen, phosphorus, mercury, zinc, and sulphur. Gorbachev is generally well regarded in the West for having ended the Cold War.

Also, Lavoisier clarified the concept of an element as a simple substance that could not be broken down by any known method of chemical analysis, and he devised a theory of the formation of chemical compounds from elements. However, he later resigned on December 25, 1991 as the USSR became defunct. His Traité Élémentaire de Chimie (Elementary Treatise of Chemistry, 1789, translated into English by Robert Kerr) is considered to be the first modern chemical textbook, and presented a unified view of new theories of chemistry, contained a clear statement of the Law of Conservation of Mass, and denied the existence of phlogiston. Gorbachev was elected as the first executive president of the Soviet Union on March 15, 1990. Their system facilitated communication of discoveries between chemists of different backgrounds and is still largely in use today, including names such as sulfuric acid, sulfates, and sulfites. In the end Yeltsin won them round too with promises of more money. He described it in Méthode de nomenclature chimique (Method of Chemical Nomenclature, 1787). But when the CPSU was proscribed after the August coup, Gorbachev was left with no effective power base beyond the armed forces.

With the French chemists Claude-Louis Berthollet, Antoine Fourcroy and Guyton de Morveau, Lavoisier devised a chemical nomenclature, or a system of names describing the structure of chemical compounds. The inherent contradictions in this approach - praising Lenin, admiring Sweden's social model and seeking to maintain the annexation of the Baltic states by military force - were difficult enough. He discovered the components of water were oxygen and hydrogen, and that air was a mixture of gases - primarily nitrogen and oxygen. Gorbachev had aimed to maintain the CPSU as a united party but move it in the direction of social democracy. Lavoisier also investigated the composition of water and air, which at the time were considered elements. Those arrested for high treason include the "Gang of Eight" that had led the coup. These experiments provided evidence for the law of the conservation of matter. Furthermore, Gorbachev was forced to fire large numbers of his Politburo and, in several cases, arrest them.

Nevertheless, the weight gained was lost from the air. However, upon his return, Gorbachev found that neither union nor Russian power structures heeded his commands as support had swung over to Yeltsin. He burnt phosphorus and sulfur in air, and proved that the products weighed more than the original. During this time, Gorbachev spent three days (August 19 to 21) under house arrest at a dacha in the Crimea before being freed and restored to power. He showed that, although matter changes its state in a chemical reaction, the quantity of matter is the same at the end as at the beginning of every chemical reaction. Conservatives in the Soviet leadership launched the August Coup in 1991 in an attempt to remove Gorbachev from power and prevent the signing of the new union treaty. Lavoisier's experiments were among the first truly quantitative chemical experiments ever performed; that is, he carefully weighed the reactants and products involved, a crucial step in the advancement of chemistry. On the eve of the treaty's signing the conservatives struck.

In Reflexions sur le Phlogistique, 1783, Lavoisier showed the phlogiston theory to be inconsistent. In contrast to the reformers' lukewarm approach to the new treaty, the conservatives, still strong within the CPSU and military establishment, were completely opposed to anything which might lead to breakup of the Soviet motherland. In 1779, he named this part of the air oxygen (Greek for acid-former), and the other azote (Greek for no life). However, the more radical reformists, such as Russian SFSR President Boris Yeltsin, were increasingly convinced that a rapid transition to a market economy was required and were more than happy to contemplate the disintegration of the USSR if that was required to achieve their aims. In Sur la combustion en general (On Combustion in general), 1777 and Considérations Générales sur la Nature des Acides (General Consideration on the Nature of Acids), 1778), he demonstrated that the "air" responsible for combustion was also the source of acidity. The new treaty was strongly supported by the Central Asian republics, who needed the economic power and markets of the Soviet Union to prosper. This tendency to use the results of others without acknowledgment, then draw conclusions is said to be characteristic of Lavoisier. Gorbachev's response to growing republic separatism was to draw up a new treaty of union which would have created a truly voluntary federation in an increasingly democratised USSR.

However, he tried to take credit for Priestley's discoveries. Gorbachev had accidentally unleashed a force that would ultimately destroy the Soviet Union. Lavoisier's work was partly based on the work of Priestley (he corresponded with Priestley and fellow members of the Lunar Society). Nationalist feeling also took hold in the Soviet republics of Georgia, Ukraine, and Azerbaijan. He also discovered that the inflammable air of Henry Cavendish which he termed hydrogen (Greek for water-former), combined with oxygen to produce a dew, as Joseph Priestley had reported, which appeared to be water. Calls for greater independence from Moscow's rule grew louder, especially in the Baltic republics of Estonia, Lithuania, and Latvia, which had been annexed into the Soviet Union by Stalin in 1940. Lavoisier's explanation of combustion replaced the phlogiston theory, which postulates that materials release a substance called phlogiston when they burn. Gorbachev's relaxation of censorship and attempts to create more political openness had the unintended effect of re-awakening long-suppressed nationalist and anti-Russian feelings in the Soviet republics.

He also demonstrated the role of oxygen in metal rusting, as well as its role in animal and plant respiration: working with Pierre-Simon Laplace, Lavoisier conducted experiments that showed that respiration was essentially a slow combustion of organic material using inhaled oxygen. Despite being an attempt to revitalize Soviet socialism, the democratization of the USSR and Eastern Europe tore away the power of the CPSU and Gorbachev himself. Through these experiments, he demonstrated that burning is a process that involves the combination of a substance with oxygen. The loosening of Soviet hegemony over Eastern Europe effectively ended the Cold War, and for this, Gorbachev was awarded the Nobel Peace Prize on October 15, 1990. Some of Lavoisier's most important experiments examined the nature of combustion, or burning. With the exception of Romania, the democratic revolutions against the pro-Soviet communist regimes were all peaceful ones. Beginning in 1775, he served in the Royal Gunpowder Administration, where his work led to improvements in the production of gunpowder and the use of agricultural chemistry by designing a new method for preparing saltpeter. Moscow's abandonment of the Brezhnev Doctrine led to a string of revolutions in Eastern Europe throughout 1989, in which communism collapsed.

In 1771, he married 13-year-old Marie-Anne Pierette Paulze, who translated from English for him, illustrated his books, and assisted him in his research. This proved to be the most far-reaching of Gorbachev's foreign policy reforms with his Foreign Ministry spokesman Gennadi Gerasimov jokingly calling his new doctrine the Sinatra Doctrine. In 1769 he worked on the first geological map of France. Also during 1988, Gorbachev announced that the Soviet Union would abandon the Brezhnev Doctrine, and allow the Eastern bloc nations to determine their own internal affairs. He was elected a member of the French Academy of Sciences in 1768 for an essay on street lighting. In February 1988, Gorbachev announced the withdrawal of Soviet forces from Afghanistan, which was completed the following year. In 1767 he worked on a geological survey of Alsace-Lorraine. This led to the signing of the Intermediate-Range Nuclear Forces Treaty (INF) in 1987.

His first chemical publication appeared in 1764. President Ronald Reagan met in Reykjavik, Iceland to discuss reducing intermediate-range nuclear weapons in Europe. He attended the College Mazarin from 1754 to 1761, studying chemistry, botany, astronomy, and mathematics. On October 11 1986, Gorbachev and U.S. Born to a wealthy family in Paris, Antoine Laurent Lavoisier inherited a large fortune when his mother died. In international affairs, Gorbachev sought to improve relations and trade with the West. . In December 1988, the Supreme Soviet approved the establishment of a Congress of People's Deputies, which constitutional amendments had established as the Soviet Union's new legislative body.

Due to his prominence in the pre-revolutionary government in France, he was beheaded at the height of the French Revolution. In June 1988, at the CPSU's Nineteenth Party Conference, Gorbachev launched radical reforms meant to reduce party control of the government apparatus. He was also an investor and administrator of the Ferme Générale, a private tax collection company; chairman of the board of the Discount Bank (later the Banque de France); and a powerful member of a number of other aristocratic administrative councils. In January 1987, Gorbachev called for democratization: the infusion of democratic elements such as multi-candidate elections into the Soviet political process. Lavoisier is often referred to as the father of modern chemistry. Gorbachev's goal in undertaking glasnost was to pressure conservatives within the CPSU who opposed his policies of economic restructuring, and he also hoped that through different ranges of openness, debate and participation, the Soviet people would support his reform initiatives. He stated the first version of the Law of Conservation of Matter, recognized and named oxygen (1778), disproved the phlogiston theory, and helped to reform chemical nomenclature. The press became far less controlled, and thousands of political prisoners and many dissidents were released.

Antoine-Laurent de Lavoisier (August 26, 1743 – May 8, 1794) was a French nobleman prominent in the histories of chemistry, finance, biology, and economics. This was a radical change, as control of speech and suppression of government criticism had previously been a central part of the Soviet system. , 1982. Gorbachev's introduction of glasnost gave new freedoms to the people, such as a greater freedom of speech.

Under this provision, cooperative restaurants, shops, and manufacturers became part of the Soviet scene. Grey, Vivian. The law initially imposed high taxes and employment restrictions, but these were later revised to avoid discouraging private-sector activity.

For the first time since Vladimir Lenin's New Economic Policy, the law permitted private ownership of businesses in the services, manufacturing, and foreign-trade sectors. Hundred Greatest Men, 1885 www.lib.utexas.edu. The Law on Cooperatives enacted in May 1987 was perhaps the most radical of the economic reforms during the early part of the Gorbachev era. Antoine Lavoisier, Elements of Chemistry, Dover Publications Inc., New York, NY,1965, 511 pages. However, many of his reforms were contrary to the beliefs of many in the Soviet government at the time. Reprinted Bruxelles: Cultures et Civilisations, 1965. Domestically, Gorbachev implemented economic reforms that he hoped would improve living standards and worker productivity as part of his perestroika program.

As de facto ruler of the Soviet Union, he tried to reform the stagnating Communist Party and the state economy by introducing glasnost ("openness"), perestroika ("restructuring"), and uskorenie ("acceleration", of economic development), which were launched at the 27th Congress of the CPSU in February 1986. Lavoisier, A. He became the Party's first leader to have been born after the Russian Revolution of 1917. Donovan, Arthur, "Antoine Lavoisier: Science, Administration, and Revolution.", Cambridge University Press, 1993.

Paris: Presses Universitaires de France, 1955. In 1984, he traveled to the United Kingdom, where he met with Prime Minister Margaret Thatcher.

Daumas, M. In 1975, he led a delegation to West Germany, and in 1983 he headed a Soviet delegation to Canada to meet with Prime Minister Pierre Trudeau and members of the Canadian House of Commons and Senate. La révolution chimique: Lavoisier. Paris: Alcan, 1890. His positions within the new CPSU created more opportunities to travel abroad that would profoundly affect his political and social views in the future as leader of the country. Berthelot, M. He was also close to Konstantin Chernenko, Andropov's successor, serving as second secretary. During this time Grigory Romanov, Nikolai Ryzhkov, and Yegor Ligachev were elevated, the latter two working closely with Gorbachev, Ryzhkov on economics, Ligachev on personnel.

With responsibility over personnel, working together with Andropov, 20 percent of the top echelon of government ministers and regional governors were replaced, often with younger men. There, he received the patronage of Yuri Andropov, head of the KGB and also a native of Stavropol, and was promoted during Andropov's brief time as leader of the Party before his death in 1984. He was elevated to the Politburo in 1979. In 1972, he headed a Soviet delegation to Belgium and two years later, in 1974, he was made a Representative to the Supreme Soviet, and Chairman of the Standing Commission on Youth Affairs.

His career moved forward rapidly, and in 1970, he was appointed First Secretary for Agriculture and the following year made a member of the Central Committee. In 1966, at age 35, he graduated from the Agricultural Institute as an agronomist-economist. Gorbachev joined the CPSU in 1952 at the age of 21. They were married in September 1953 and moved to Gorbachev's home region of Stavropol in southern Russia when he graduated in 1955.

He studied law at Moscow University, where he met his future wife, Raisa. Mikhail Gorbachev was born into a peasant family in the village of Privolnoye near Stavropol. . His attempts at reform led to the end of the Cold War, but also caused the end of the political supremacy of the Communist Party of the Soviet Union (CPSU) and the dissolution of the Soviet Union.
