Antoine Lavoisier: Who‚ What‚ When‚ Why‚ and How? Lavoisier is regarded as the founder of modern chemistry. Born in Paris‚ he studied both law and science‚ but after graduating concentrated his attention on science. He invested his money in a private tax-collecting company‚ the Ferme Generale‚ and thereby became rich enough to build a large and well-equipped laboratory. He then proceeded to study combustion. During the 18th century combustible matter was thought to contain a substance called

Antoine Lavoisier‚ a French chemist‚ revolutionized chemistry in the late 1700’s. He repeated many of the experiments of earlier chemists but interpreted the results far differently. Lavoisier paid particular attention to the weight of the ingredients involved in chemical reactions and of the products that resulted. He found that the weight of the products of combustion equals that of the original ingredients. His discovery became known as the law of the conservation of matter. Lavoisier noted that
