Claude Louis Berthollet (9 December 1748 – 6 November 1822) was a Savoyard-French chemist who became vice president of the French Senate in 1804.^[1] He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature. On a practical basis, Berthollet was the first to demonstrate the bleaching action of chlorine gas, and was first to develop a solution of sodium hypochlorite as a modern bleaching agent.

Awards and honors[edit]

During his lifetime, Guyton de Morveau received the cross of the Legion of Honour (1803) and was made an Officer of the Legion of Honour for service to humanity (1805). He was made a baron of the First French Empire in 1811.[12][13]

Louis Bernard Guyton de Morveau‘s 1788 publication entitled Méthode de Nomenclature Chimique, published with colleagues Antoine Lavoisier, Claude Louis Berthollet, and Antoine François, comte de Fourcroy,^[14] was honored by a Citation for Chemical Breakthrough Award from the Division of History of Chemistry of the American Chemical Society, presented at the Académie des Sciences (Paris) in 2015.^[15][16]

Guyton de Morveau died in Paris on 2 January 1816.^[12]
