A Life of Science and Discovery
Louis Joseph showed a great interest in science from a young age. When his father passed away in 1769, Louis Joseph became the Duke of Picquigny. His passion for science led him to become a respected member of the scientific community. In 1764, he was chosen as a Fellow of the Royal Society in London, which is a big honor for scientists.
Early Scientific Work
At just 24 years old, Louis Joseph decided to leave his military career as a colonel to focus entirely on studying natural sciences. He made several important discoveries in chemistry.
In 1775, he proved that the gas produced during the brewing of beer was actually carbon dioxide. He also showed a simple way to make fizzy water by shaking water over vats where beer was fermenting. He even found a method to make certain chemicals form crystals using carbon dioxide from beer.
A Brave Experiment
Scientists at the time knew that breathing in fumes from burning coal could be dangerous because of carbon dioxide. Chaulnes wanted to find a way to help people who had breathed in too much of this gas. He suggested using ammonia gas to help them recover.
After successfully trying his method on animals, he wanted to test it on himself. He gave clear instructions to his assistant. Then, he bravely locked himself inside a glass box with burning charcoal, which produces carbon dioxide.
"When you see me fall," he said, "take me out of the cabinet and help me as I've taught you to do."
His assistant followed the instructions quickly, and Louis Joseph recovered, proving his method could work!
Travels and Writings
Louis Joseph also loved to travel. In 1763, he visited Egypt and made very accurate drawings of ancient monuments that had not been properly described before. He published a paper in 1783 about an Egyptian monument near Cairo, known as the Well of Birds, which was a tomb for sacred animals. In his paper, he shared interesting details about his attempts to make copies of the amazing hieroglyphs found there.
He also published another important paper in 1780 called Mémoire et Expériences sur l'air fixe qui se dégage de la bière en fermentation. This paper was about the gas that comes from fermenting beer, showing his continued interest in this area of chemistry.
