In 1789, French nobleman and scientific researcher Antoine Lavoisier discovered the law of conservation of mass and defined an element as a basic substance that could not be further broken down by the methods of chemistry.

Pierre-Simon Laplace and Antoine Lavoisier, in their 1780 treatise on heat, arrived at values ranging from 1, 500 to 3, 000 below the freezing-point of water, and thought that in any case it must be at least 600 below.

Antoine-Laurent de Lavoisier ( also Antoine Lavoisier after the French Revolution ; 26 August 17438 May 1794 ; ), the " father of modern chemistry ," was a French nobleman prominent in the histories of chemistry and biology.

With the French chemists Claude-Louis Berthollet, Antoine Fourcroy and Guyton de Morveau, Lavoisier devised a systematic chemical nomenclature.

The first of these scientific concepts of acids and bases was provided by the French chemist Antoine Lavoisier, circa 1776.

Chemistry came of age when Antoine Lavoisier ( 1743 – 1794 ) developed the theory of Conservation of mass in 1783 ; and the development of the Atomic Theory by John Dalton around 1800.

It is because of these and other contributions that Antoine Lavoisier is often celebrated as the " Father of Modern Chemistry ".

Antoine Lavoisier ( 1743 – 94 ) is considered the " People known as the father or mother of something | Father of Modern Chemistry ".

Chemistry as we know it today, was invented by Antoine Lavoisier with his law of Conservation of mass in 1783.

Antoine Lavoisier conducting an experiment related combustion generated by amplified sun light.

Antoine Lavoisier developed the theory of combustion as a chemical reaction with oxygen

This proved to be false in 1785 by Antoine Lavoisier who found the correct explanation of the combustion as reaction with oxygen from the air.

By the time of Antoine Lavoisier, for example, a list of elements would no longer refer to classical elements.

The world ’ s first ice-calorimeter, used in the winter of 1782-83, by Antoine Lavoisier and Pierre-Simon Laplace, to determine the heat evolved in various chemical change s ; calculations which were based on Joseph Black ’ s prior discovery of latent heat.

Berthollet, along with Antoine Lavoisier and others, devised a chemical nomenclature, or a system of names, which serves as the basis of the modern system of naming chemical compounds.

In 1772, Antoine Lavoisier used a lens to concentrate the rays of the sun on a diamond in an atmosphere of oxygen, and showed that the only product of the combustion was carbon dioxide, proving that diamond is composed of carbon.

For example, in 1788, he painted a portrait of Antoine Lavoisier and his wife.

After he discovered that France was not self-sufficient in gunpowder, a Gunpowder Administration was established ; to head it, the lawyer Antoine Lavoisier was appointed.

French scientists such as Antoine Lavoisier worked to replace the archaic units of weights and measures by a coherent scientific system.

Three of the board members include a founding father of modern chemistry Antoine Lavoisier, Benjamin Franklin and an expert in pain control Joseph-Ignace Guillotin.

* Antoine Lavoisier

The name is based on the genus Polygonum and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum.

The person celebrated as the " father of modern chemistry " is Antoine Lavoisier ( 1743 – 1794 ) who developed his law of Conservation of mass in 1789, also called Lavoisier's Law.

In 1789, Antoine Lavoisier securely differentiated chemistry from alchemy by introducing rigor and precision into his laboratory techniques ; allowing him to deduce the conservation of mass and categorize many new chemical elements and compounds.

* 1789: Antoine Lavoisier discovers the law of conservation of mass, the basis for chemistry, and begins modern chemistry

In 1789 Antoine Laurent de Jussieu classified all climbing aroids as Pothos and all terrestrial aroids as either Arum or Dracontium in his book Families des Plantes.

The family was described by Antoine Laurent de Jussieu in 1789.

In 1789, Antoine Laurent de Jussieu, nephew of Bernard de Jussieu, published that classification scheme.

The family Amaranthaceae was first published in 1789 by Antoine Laurent de Jussieu in Genera Plantarum, p. 87 – 88.

He was sent to school in the faubourg St. Antoine, and from its roof witnessed the storming of the Bastille in 1789 – commemorated in his poem, " Le quatorze juillet " ( The 14th of July ).

The family name is attributed to Antoine Laurent de Jussieu's 1789 Genera Plantarum, secundum ordines naturales disposita juxta methodum in Horto Regio Parisiensi exaratam, and is a conserved name, so that even if an earlier name were to be discovered for the family, Iridaceae would remain valid.

The success of this work was hindered by its innovations in the use of terms, which were ridiculed by the defenders of the popular sexual system of Linnaeus ; but it did much to open the way for the establishment, by means principally of Antoine Laurent de Jussieu's Genera Plantarum ( 1789 ), of the natural method of the classification of plants.

* 1789 – Antoine Lavoisier: law of conservation of mass, basis for chemistry, and the beginning of modern chemistry

He translated several scientific works into English, such as Antoine Lavoisier's Traité Élémentaire de Chimie in 1789.

The first European to describe these plants was Philibert Commerçon, a French botanist accompanying French Navy admiral and explorer Louis Antoine de Bougainville during his voyage of circumnavigation, and first published for him by Antoine Laurent de Jussieu in 1789.

From 1780 until 1789, Louis Antoine and his younger brother, Charles Ferdinand, Duke of Berry, were educated by the marquis de Sérent, their gouverneur, in the château de Beauregard, a few miles from Versailles.

Carolus Linnaeus first classified G. sempervirens as Bignonia sempervirens in 1753 ; Antoine Laurent de Jussieu renamed the genus in 1789.

Despite all these advances, the person celebrated as the " father of modern chemistry " is Antoine Lavoisier who developed his law of conservation of mass in 1789, also called Lavoisier's Law.

His grandfather, Antoine Louis Marie, duc de Gramont ( 1755 – 1836 ), had emigrated during the French Revolution, and his father, Antoine Heraclius Genevieve Agenor ( 1789 – 1855 ), duc de Gramont and de Guiche, fought under the British flag in the Peninsular War, became a lieutenant-general in the French army in 1823, and in 1830 accompanied Charles X of France to Scotland.

It was established in 1789 by Antoine Laurent de Jussieu.
