Scheele, KARL WILHELM, born in 1742, showed an early taste for chemical study, and followed for some years the business of apothecary at Stockholm, Upsala, and Koping. He discovered, among other valuable products, oxygen, chlorine, barytes, fluoric and tartaric acid, arsenite of copper (Scheele's green), glycerine, and prussic acid.
