* Henry Cavendish (1731-1810): He first observed the formation of water from the reaction of hydrogen with oxygen in 1766. He called the resulting substance "inflammable air" and observed that it produced "dephlogisticated air" (oxygen) upon burning.
* Joseph Priestley (1733-1804): He independently discovered oxygen in 1774 and conducted experiments on the reaction of hydrogen with oxygen, further solidifying the connection between these gases and water.
* Antoine Lavoisier (1743-1794): He is credited with developing the modern understanding of chemical reactions and elements. He conducted extensive research on the composition of water, naming it "hydrogen oxide" and establishing the correct ratio of hydrogen and oxygen in its formation.
Therefore, it's more accurate to say that the discovery of the composition of water was a collaborative effort, with each of these scientists making significant contributions.
