Antoine-Laurent Lavoisier, often called the father of modern chemistry, helped name hydrogen following experiments that demonstrated the composition of water.1
While the English chemist Henry Cavendish had previously identified the gasâthen referred to as "inflammable air"âas a distinct substance, it was Lavoisier who confirmed that water is a chemical compound formed by the combustion of this gas with oxygen.12
Based on this discovery, Lavoisier coined the French term hydrogène, which is derived from Greek words meaning "water producer" or "maker of water". This name reflects the fundamental observation that the gas generates water when it burns.123
