Antoine Lavoisier was a French chemist born in 1743, often called the "Father of Modern Chemistry." He is best known for his role in establishing the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Lavoisier's work laid the foundation for modern chemical nomenclature and helped to clarify the roles of elements and compounds. Lavoisier also played a crucial role in debunking the phlogiston theory, which was a popular explanation for combustion at the time. His experiments led to the discovery of oxygen and hydrogen, which are essential elements in chemistry. Sadly, Lavoisier's life was cut short during the French Revolution, but his contributions continue to influence science today.
