On This Day – Sep 30 : Discovery of oxygen
Unfortunately the letter from the Swedish chemist was never acknowledged and Joseph Priestley 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”.
