Antoine Lavoisier (1743-1794) was the father of modern chemistry.

His researches included some of the first truly quantitative chemical experiments. He carefully weighed the reactants and products in a chemical reaction, taking thereby a crucial step in the advancement of chemistry. He showed that, although matter can change its state in a chemical reaction, the quantity of matter is the same at the end as at the beginning of every chemical change.

He investigated the composition of water and air, which at the time were considered to be elements. He determined that the components of water were oxygen and hydrogen and that air was a mixture of gases. With other French chemists, Lavoisier devised a systematic chemical nomenclature. This nomenclature facilitated communication of discoveries between chemists of different backgrounds. Still largely in use today, it includes names such as sulfuric acid, sulfates, and sulfites.
