Father of Modern Chemistry. Lavoisier figured out that burning things needs oxygen from the air, and he explained what happens when things burn better than anyone ever had before. His ideas completely changed chemistry from guessing games into a real science with real rules.

Discovered Oxygen's Role. He proved that air isn't just one simple thing, but a mixture of gases including oxygen. When something burns, it combines with oxygen, which is why we need air to keep fires going.

Careful Measurements Matter. Lavoisier weighed everything super carefully before and after his experiments, and he noticed that matter never disappears, it just transforms into something else. This idea, called the law of conservation of mass, became one of chemistry's most important rules.

Named Important Elements. He didn't just discover things, he also gave clear names to many elements and gases that scientists still use today. His organization helped other scientists understand how all the different materials in the world fit together.
