On This Day In Chemistry

September 30th

Carl Wilhelm Scheele sent a letter to Antoine Lavoisier announcing the discovery of oxygen (O) on this day in 1774

Unfortunately the letter from the Swedish chemist was never acknowledged and Joseph Priestly published the discovery first. Scheele was trounced in the announcement of other discoveries as well. For this reason, Isaac Asimov nicknamed him “hard-luck Scheele”.
