Antoine Lavoisier
However, his first publication, "Chemische Abhandlung von der Luft und dem Feuer", was delivered to the printer Swederus in 1775, but not published until 1777, at which time both Joseph Priestley and Antoine Lavoisier had already published their experimental data and conclusions concerning oxygen and the phlogiston theory. Carl was credited for finding oxygen with two other people, Joseph Priestley and Antoine Lavoisier. The first English edition, "Chemical Observation and Experiments on Air and Fire" was published in 1780, with an introduction "Chemical Treatise on Air and Fire".
