Carl Wilhelm Scheele but it wasn't until 1810 when it was identified as Chlorine by Sir Humphry Davy.
Chlorine was observed for the first time by Jan Baptist van Helmont near 1630 (in Holland) and prepared for the first time in laboratory by Carl Wilhelm Scheele in 1774 (in Sweden), but considered it to be a compound of oxygen. Sir Humphry Davy (in England) named it after identifying chlorine as a chemical element in 1810.
