Oxygen was "discovered" by a number of scientists over a fairly brief time period. Antoine Lavoisier also claimed to have discovered oxygen, and he proposed that the new gas be called oxy-gène, meaning acid-forming, because he thought it was the basis of all acids. Unknown to Priestly, Carl Wilhelm Scheele had produced oxygen in June 1771. The major credit though goes to Joseph Priestley as he was the first one to publish his findings. When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn.

Who discovered the Oxygen. Joseph Priestley - Joseph Priestley - The discovery of oxygen and the chemical revolution: Priestley’s lasting reputation in science is founded upon the discovery he made on August 1, 1774, when he obtained a colourless gas by heating red mercuric oxide.
