Definition
Meaning
A proper noun referring to Antoine-Laurent de Lavoisier (1743–1794), the French nobleman and chemist widely regarded as the father of modern chemistry.
Used metonymically to refer to his scientific contributions, such as the law of conservation of mass, the modern system of chemical nomenclature, or the understanding of combustion and oxygen.

Not in standard modern English. The adjectival form is rarely used; one would say 'Lavoisier's work' or 'Lavoisierian' in specialised historical texts.
He is considered the founder of modern chemistry for his systematic approach, his role in establishing the law of conservation of mass, his work on combustion and gases, and his development of a logical chemical nomenclature.
