Christian Friedrich Schönbein, a German scientist, is credited with the discovery of ozone in 1839.
Schönbein first produced ozone in the laboratory and subsequently identified it as a distinct chemical substance. His experiments and research laid the groundwork for understanding ozone's properties and its role in the atmosphere. He published his findings in 1840. While ozone had been observed prior to Schönbein's work, he was the first to characterize and name it.
