Antoine Lavoisier (1743-94)
Born into a wealthy French family, Antoine Lavoisier is considered to be the founder of modern chemistry. He and his wife Marie-Anne Pierrette Paulze collaborated on numerous scientific projects.
Lavoisier was a polymath, inspired by the ideas of the Enlightenment. His studies included philosophy and law and he invented many new instruments and very accurate quantitative methods to analyse the elements contained in chemical compounds. These inventions led him to identify the element oxygen. He also developed a new method of chemical nomenclature: a way of naming chemical substances which, with modifications, is still in use today.
Lavoisier’s work as a tax collector for the king led to him being executed by the French revolutionaries on the guillotine. After Lavoisier’s execution, his wife continued to fight for recognition of his ideas, bringing together and publishing his final work.
