[[Chlorine]] was discovered in 1774 by Swedish chemist [[Carl Wilhelm Scheele]], who called it ''"dephlogisticated marine acid"'' (see [[phlogiston theory]]) and mistakenly thought it contained [[oxygen]]. Davy showed that the acid of Scheele's substance, called at the time [[Chlorine#History|oxymuriatic acid]], contained no [[oxygen]]. This discovery overturned [[Antoine Lavoisier|Lavoisier's]] definition of acids as compounds of oxygen.<ref name="Distillations" /> In 1810, chlorine was given its current name by Humphry Davy, who insisted that chlorine was in fact an [[Chemical element|element]].<ref>{{cite journal|last = Davy|first = Humphry|title = On Some of the Combinations of Oxymuriatic Gas and Oxygene, and on the Chemical Relations of These Principles, to Inflammable Bodies|journal = Philosophical Transactions of the Royal Society|volume = 101|pages = 1–35|year = 1811|doi = 10.1098/rstl.1811.0001|url = https://zenodo.org/record/1432322|doi-access = free|bibcode = 1811RSPT..101....1D|access-date = 9 September 2019|archive-date = 1 August 2020|archive-url = https://web.archive.org/web/20200801214422/https://zenodo.org/record/1432322|url-status = live}}</ref> The name chlorine, chosen by Davy for "one of [the substance's] obvious and characteristic properties – its colour", comes from the Greek χλωρος (chlōros), meaning green-yellow.
