08/05/1794 French chemist Antoine-Laurent Lavoisier dies at age 50

Antoine-Laurent de Lavoisier was a French nobleman and chemist who was central to the 18th-century chemical revolution and who had a large influence on both the history of chemistry and the history of biology. He was also a powerful member of a number of aristocratic councils and an administrator of the Ferme générale, one of the most hated components of the Ancien Régime, the monarchy and feudal system of France up to 1789. At the height of the French Revolution, he was charged with tax fraud and selling adulterated tobacco, and was subsequently guillotined.
