Antoine-Laurent de Lavoisier (26 August 1743 – 8 May 1794) He is also known to be “the father of modern chemistry.” He was a nobleman famous in the histories of Chemistry and Biology; he also stated the first version of the Law of Conservation of Mass, named oxygen and hydrogen, abolished the phlogiston theory and also helped construct the metric system.
He also wrote the first extensive list of elements and helped to reform chemical nomenclature. An investor and administrator of the "Ferme Générale" (a private tax collection company); He was also the chairman of the board of the Discount Bank. He was accused by Jean-Paul Marat of selling watered-down tobacco and of other crimes and of guillotined (behead).
1789 - The principle of conservation of mass was first outlined clearly by Antoine Lavoisier (1743–1794)
It has been claimed that Mikhail Lomonosov (1711–1765) had expressed similar ideas during 1748—and proved them by experiments—but this has been challenged.[6] Others who anticipated the work of Lavoisier include Joseph Black (1728–1799), Henry Cavendish (1731–1810), and Jean Rey (1583–1645).
Antoine is born of a wealthy family from Paris. He was able to inherit a large fortune when he was 5 years old because of his mother’s death.
He Studied in the College of Mazarin from 1754 to 1761. He studied Chemistry, Botany, Astronomy and Mathematics.
1748 - The Law of Conservation of Mass was first stated at a physical theory by Russian scientist Mikhail Lomonosov
1767- Lavoisier worked on a geological survey of Alsace-Lorraine. When he was 25, he was elected as a member of French Academy of Sciences.
1771- at the age of 28, Lavoisier married the 13-year-old Marie-Anne Pierrette Paulze, the daughter of a co-owner of the Ferme. Over time, she proved to be a scientific colleague to her husband. She translated documents from English for him, including Richard Kirwan's Essay on Phlogiston and Joseph Priestley's research. She created many sketches and carved engravings of the laboratory instruments used by Lavoisier and his colleagues. She edited and published Lavoisier’s memoirs (whether any English translations of those memoirs have survived is unknown as of today) and hosted parties at which eminent scientists discussed ideas and problems related to chemistry.
1789 - This theory (the Law of Conservation of Mass) was later reiterated and confirmed by French scientist Antoine Lavoisier . Lavoisier verified his theory in practice by carrying out a number of carefully measured experiments in which he reacted tin and lead with oxygen.
