Antoine-Laurent Lavoisier, French Chemist
Lavoisier combining oxygen and hydrogen with an electric spark to form water. Antoine-Laurent Lavoisier (August 26, 1743 - May 8, 1794) was a French chemist who is considered the founder of modern chemistry. He changed the science from a qualitative to a quantitative one. He is noted for his discovery of the role oxygen plays in combustion. He recognized and named oxygen (1778) and hydrogen (1783) and opposed the phlogiston theory. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. He predicted the existence of silicon (1787) and was also the first to establish that sulphur was an element (1777) rather than a compound. He discovered that, although matter may change its form or shape, its mass always remains the same. His book Methods of Chemical Nomenclature of 1787 set the method of naming substances by their composition of elements, which is still used today. As the
