Charles Coüasnon
Charles Coüasnon was a French scientist who lived a long time ago. He liked to study how different things work and how they can be used to make new things.
One thing he studied a lot was something called "oxygen". Oxygen is a gas that we breathe in from the air, and it helps us stay alive. But Charles Coüasnon found out that oxygen could also be used to make things burn more quickly.
He also discovered a way to measure the amount of oxygen in the air by using a special tool called a "thermometer". This was really important because it helped people understand more about the air we breathe and how it affects things around us.
Overall, Charles Coüasnon was a smart scientist who taught us a lot about oxygen and how it can be used.
