Scheele's Priority for the Discovery of Oxygen
Cassebaum, H.; Schufle, J. A.
Journal of Chemical Education, 52, 7, 442-444, Jul 75
Concludes that Carl Scheele first observed oxygen and clearly understood what he was observing in June 1771, when he heated manganese dioxide with concentrated sulfuric acid. This was more than three years before Lavoisier or Priestley (who is usually credited with the discovery of oxygen) made similar observations. (Author/MLH)
