Oxygen was discovered by the Swedish chemist Carl Wilhelm Scheele in 1772, almost simultaneously with the English scientist Joseph Priestley. However, it was the French chemist Antoine Lavoisier who named the element "oxygen" and recognized its role in combustion and respiration.
He discovered that oxygen is present in the burning of matter.
The scientist who is credited with discovering oxygen is Joseph Priestley, an English chemist and clergyman. He isolated oxygen in 1774 by heating mercuric oxide and noting the release of a gas that enhanced combustion.
