He gave names to two important elements: nitrogen and oxygen. Lavoisier was the first man to draw up a lengthy list of elements, allowing him to predict the future discovery of silicon.

He was arrested and eventually executed during the French Revolution, having been accused of selling adulterated tobacco.

Lavoisier was born in Paris to a wealthy family; he became rich on a large inheritance from his mother.

He showed that oxygen was necessary for burning to take place, and that the element was also important in the respiration of living organisms, as well as being the driving force behind the formation of rust on metal. His results discredited the phlogiston theory, which had suggested that a substance of that name was released by burning objects.

He corresponded with Joseph Priestley, who had previously worked on this problem, but he attempted to take all the credit for himself, a fault he displayed on other occasions, too. In further examples, he demonstrated that the quantity of matter remains the same after it changes state, and that the weight gained by sulfur and phosphorus when burned was taken from the air; these results supported the law of matter conservation.
