See Article History Antoine-Laurent Lavoisier, born August 26,Paris, France—died May 8,Parisprominent French chemist and leading figure in the 18th-century chemical revolution who developed an experimentally based theory of the chemical reactivity of oxygen and coauthored the modern system for naming chemical substances. Having also served as a leading financier and public administrator before the French Revolutionhe was executed with other financiers during the revolutionary terror.
Biography Early life and education Antoine-Laurent Lavoisier was born to a wealthy family of the nobility in Paris on 26 August The son of an attorney at the Parliament of Paris, he inherited a large fortune at the age of five upon the death of his mother.
In his last two years — at the school, his scientific interests were aroused, and he studied chemistrybotanyastronomyand mathematics. Lavoisier received a law degree and was admitted to the barbut never practiced as a lawyer.
However, he continued his scientific education in his spare time. He attended lectures in the natural sciences. His first chemical publication appeared in In collaboration with Guettard, Lavoisier worked on a geological survey of Alsace-Lorraine in June In Lavoisier received a provisional appointment to the Academy of Sciences.
Lavoisier as a social reformer Research benefitting the public good While Lavoisier is commonly known for his contributions to the sciences, he also dedicated a significant portion of his fortune and work toward benefitting the public.
The goal was to bring in water from the river Yvette into Paris so that the citizens could have clean drinking water. But, since the construction never commenced, he instead turned his focus to purifying the water from the Seine.
This was the project that interested Lavoisier in the chemistry of water and public sanitation duties. In addition, she assisted him in the laboratory and created many sketches and carved engravings of the laboratory instruments used by Lavoisier and his colleagues for their scientific works.
Completed in on the eve of the Revolution, the painting was denied a customary public display at the Paris Salon for fear that it might inflame anti-aristocratic passions. He did, however, present one important memoir to the Academy of Sciences during this period, on the supposed conversion of water into earth by evaporation.
By a very precise quantitative experiment Lavoisier showed that the "earthy" sediment produced after long-continued reflux heating of water in a glass vessel was not due to a conversion of the water into earth but rather to the gradual disintegration of the inside of the glass vessel produced by the boiling water.
He also attempted to introduce reforms in the French monetary and taxation system to help the peasants.
Adulteration of tobacco The Farmers General held a monopoly of the production, import and sale of tobacco in France, and the taxes they levied on tobacco brought revenues of 30 million livres a year. However this revenue began to fall because of a growing black market in tobacco that was smuggled and adulterated, most commonly with ash and water.
Lavoisier devised a method of checking whether ash had been mixed in with tobacco: Of one vendor selling adulterated goods he wrote "His tobacco enjoys a very good reputation in the province Perhaps the Farm could gain some advantage by adding a bit of this liquid mixture when the tobacco is fabricated.
Thereafter the factories of the Farmers General added, as he recommended, a consistent 6. He was energetic and rigorous in implementing this, and the systems he introduced were deeply unpopular with the tobacco retailers across the country. This unpopularity was to have consequences for him during the French Revolution.
He then served as its Secretary and spent considerable sums of his own money in order to improve the agricultural yields in the Solognean area where farmland was of poor quality. The humidity of the region often led to a blight of the rye harvest, causing outbreaks of ergotism among the population.Dec 10, · In the 18th century the discoveries of the French scientist Antoine Lavoisier were so important that today he is thought of as being the founder of modern chemistry.
He became the first person to isolate and name the element oxygen, which is the most common element on Earth. combustible substance (such as carbon) with oxygen. Perhaps the most profound contribution by Antoine Lavoisier, a key figure in the emerging field of chemistry in the late 18th century, was his insistence that chemistry be based on experiments and.
Lavoisier's discoveries introduced a new way to study elements, launching modern chemistry. Early Life In , Antoine Lavoisier was born in Paris, France to a wealthy family.

Explain the calx-retort experiment. Mercury was heated in a retort, linked to a bell jar, calx (mercury oxide) formed in the retort, and the volume reduced in the jar. When reheated, the calx released oxygen, and was equal to the amount of air lost. Antoine Lavoisier is commonly cited as a central contributor to the chemical revolution.
His precise measurements and meticulous keeping of balance sheets throughout his experiment were vital to the wide spread acceptance of the law of conservation of regardbouddhiste.com mater: Collège des Quatre-Nations, University of Paris.
