Antoine Lavoisier (1743-1794) Antoine-Laurent Lavoisier (lah vwah ZYAY) was one of the best-known French scientists and was an important government official. His theories of combustion, his development of a way to classify the elements and the first modern textbook of chemistry led to his being known as the father of modern chemistry. He contributed to much of the research in the field of chemistry. He is quoted for saying, "Nothing is lost, nothing is created, everything is transformed." Lavoisier was born in Paris, France on Aug. 26, 1743. When he was eleven years old he attended a college called Mazain. For Lavoisier's last two years in college he found a great deal of interest in science. He received an excellent education and …show more content…
On 1772 he was studying on combustion, which he is most known for in science. Lavoisier presented an important memoir on conversion of water into earth evaporation. This brought him to the Oxygen Theory of Combustion. On 1774 Lavoisier carried out experiments on calcinations of tin and lead and confirmed the increase of weight of metals on calcinations from combustion of air. By demonstrating the nature of combustion, he disproved the phlogiston theory. The phlogiston theory stated that all flammable materials contained a substance called phlogiston. According to this theory, materials gave off phlogiston as they burned. Air was necessary for combustion because it absorbed the phlogiston that was released. This was thought at the time to be a fact. Lavoisier showed this theory to be false and made oxygen the reason that things burned, not phlogiston. Lavoisier burned textbooks that supported the theory. He was trying to make a point that the phlogiston theory was invalid and oxygen is the new answer to combustion. He laid the framework for understanding chemical reactions as combinations of elements to form new materials, or products. He concluded that combustion results from the rapid chemical union of a flammable material with a newly discovered gas, which he named "oxygen", previously known as "dephilogisticated air." The word "oxygen" means acid producer. Lavoisier and others had found that oxygen is a part of several acids. Lavoisier incorrectly
