The father of modern chemistry is widely recognized as Antoine-Laurent Lavoisier. He revolutionized the field by transforming chemistry from a qualitative to a quantitative science, establishing the law of conservation of mass, and identifying oxygen's role in combustion and respiration. Lavoisier also helped systematize chemical nomenclature, named oxygen, and wrote the foundational text Traité élémentaire de Chimie in 1789. His meticulous experiments and clear classification of elements laid the groundwork for modern chemical science

. While others like Jabir ibn Hayyan (Geber) and Robert Boyle contributed significantly to chemistry's history, Lavoisier's work marks the beginning of chemistry as a precise and systematic science, earning him the title "father of modern chemistry"
