Antoine Lavoisier 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 …show more content…
He noted that the weight of the air in which combustion occurred decreases. He found that when the burning material combined with the air somehow and that the air weighed less.

Lavoisier found that the weight of the products of combustion equals the weight of the reacting ingredients. This observation became known as the law of conservation of mass (or matter). He repeated many of the experiments of earlier chemists but interpreted the results far differently. 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
