the first to state this‚ but this is false. The first to state this was actually Jean Ray who had come up with a similar law. This law only became established after Lavoisier discovered it. Lavoisier produced his book Elementary Treatise on Chemistry. In this book he states the difference between a compound and an element‚ since so many people did not know the difference. This book also included the idea that light was a chemical element. He also stated in his book that there was a substance

After revolutionizing chemistry‚ naming elements‚ discovering combustion and respiration‚ Antoine Lavoisier helped transform chemistry from a qualitative science into a quantitative one. Antoine Lavoisier was born on August 26‚ 1743 in France’s Capital‚ Paris. Antoine’s father was Jean-Antoine Lavoisier‚he was a lawyer in the Paris Parliament while his mother‚ was Émilie Punctis‚ and her family wealth had come from a butchery business. Antoine’s mother died while he was five leaving him a large inheritance
