Antoine Lavoisier
1743–1794
Helping create modern chemistry and discovering the role of oxygen in chemical reactions
Early Life
Antoine Lavoisier was born in Paris, France, in 1743. As a child, he loved learning and asked many questions about how the world worked. He was especially curious about science and nature.
Antoine studied many subjects, including math, astronomy, and chemistry. Even though he trained to be a lawyer, his true passion was science. He spent much of his free time doing experiments and reading scientific books.
Discovering a New Way to Do Science
Before Antoine’s time, chemistry was confusing and full of guesses. Many scientists did not measure things carefully. Antoine believed that good science should be based on careful experiments and exact measurements.
He began using a scale to weigh materials before and after experiments. This helped him discover an important rule called the Law of Conservation of Mass. It means that matter is not created or destroyed—it only changes form.
Amazing Achievements
Antoine Lavoisier helped discover the role of oxygen in burning and breathing. He showed that fire needs oxygen to burn, which helped explain how combustion works.
He also helped name many chemical elements and compounds. Some of the names we still use today came from his work. Because of this, Antoine is often called the “Father of Modern Chemistry.”
Helping Others Learn
Antoine didn’t just do experiments—he also wanted others to understand science. He wrote clear textbooks that explained chemistry in a simple and organized way. These books helped students and scientists all over the world.
He worked with his wife, Marie-Anne Lavoisier, who drew pictures of his experiments and helped translate scientific works. Together, they made science easier to share and understand.
Legacy
Antoine Lavoisier’s ideas changed how scientists study chemistry. His careful methods are still used in laboratories today. Even though he lived long ago, his discoveries continue to help people learn about the world.
He is remembered as a scientist who brought order, clarity, and excitement to chemistry. His work reminds us that asking questions and measuring carefully can lead to amazing discoveries.
