In around **1772**, Swedish chemist and pharmacist **Carl Wilhelm Scheele** produced and studied a gas that we now know as **oxygen**. He called it **“fire air”** because he observed that it strongly supported combustion.
Scheele’s experiments helped reveal that the air around us was not simply one single substance. Instead, it contained different gases with different properties. His work became an important part of the development of modern chemistry.
**Who was Carl Wilhelm Scheele?**
Carl Wilhelm Scheele (1742–1786) was a Swedish chemist and pharmacist known for his experimental work with many substances. He investigated gases, minerals, acids, and other chemicals and made several important observations during his scientific career.
**Why is oxygen so important?**
Oxygen is essential for most forms of life on Earth. Humans and many other organisms use oxygen during **cellular respiration**, a process that helps cells release energy from food. Oxygen also plays an important role in combustion and many chemical reactions.
**A fascinating part of the story:**
The history of oxygen’s discovery involved more than one scientist. Scheele investigated oxygen around **1772**, while **Joseph Priestley** independently produced and studied the gas in **1774**. Later, **Antoine Lavoisier** helped establish oxygen’s role in combustion and respiration and gave the element its name.
**Quick facts:**
Element: **Oxygen**
Chemical symbol: **O**
Atomic number: **8**
Scheele’s work: **around 1772**
Scheele’s name for it: **“Fire air”**
Oxygen is essential for life and many natural and chemical processes.
From a laboratory experiment centuries ago to our understanding of the atmosphere today, the discovery of oxygen shows how scientific knowledge develops through **careful observation, experimentation, and the work of multiple scientists**.
**Science is full of discoveries that changed the way we understand our world!**
