|Scheele (shā'lə) Pronunciation Key
Swedish chemist who discovered a number of compounds and elements. He discovered oxygen around 1771, but because the results of his experiments were not published until 1777, Joseph Priestley is usually credited with the discovery. Scheele made extensive investigations of plant and animal materials, and his work was fundamental to the development of organic chemistry.
