French chemist and biologist

French chemist and biologist
French chemist known as the 'father of modern chemistry', who discovered the role of oxygen in combustion and helped reform chemical nomenclature.
Born in 1743, Lavoisier established the law of conservation of mass. He named oxygen and hydrogen and helped systematize chemical nomenclature. His work in quantitative chemistry laid foundations for modern chemical reactions. He was instrumental in developing the metric system. Despite his scientific achievements, he was executed during the French Revolution in 1794. His methods remain central to chemical science today.
