He became justifiably famous for his atomic theory, but true to his Quaker convictions continued to live a very simple life. He became a professor at the University of Manchester in his mid twenties. Born in Eaglesfield, England in the family of a poor weaver, John was a child prodigy who started his own school at the age of 12.

John Dalton (1766-1844) proposed the basic atomic theory which forms the cornerstone of modern chemistry. The search for the basic structure of matter. The persistent work of Lavoisier established oxygen as a pure substance with particular chemical properties - so he is often credited with discovering that pure matter consists of chemical elements. Some substances formed solid oxides and thus gained mass when burning, while others produced gaseous oxides which were given off and therefore decreased in mass. After it was done burning and there was only ash left, he took the weight of the container again. He would then weigh, for example, wood it in the container and burn it. Antoine then built an apparatus with sealed containers. This was not an easy task with the tools he had at hand. Antoine knew that gases escaped when burning substances, so he wanted to capture the gases and take the weight of them. This required quantitative experiments in close containers in order to keep track of the mass of the gases. Lavoisier performed many quantitative experiments with combustion, and concluded that the gas oxygen was being added to the substance which was burning. He wrote the first modern chemistry textbook in 1789. He discovered the role of oxygen in combustion and established the principles for naming chemicals. Some Chemistry History Lavoisier, the Father of ChemistryĪntoine Lavoisier (lah-vwah-ZHAY), 1743-1794, introduced quantitative measurement into the study of chemistry with his discovery of the law of conservation of mass.
