August 7, 1837: Death of Chester Averill who was Professor of Chemistry at Union College in Schenectady, New York. Averill is known for a letter that he wrote to the Mayor of Schenectady, New York during the 1832 cholera epidemic which praised the disinfecting properties of chloride of lime (chlorine). The treatise quoted many learned men of the time who demonstrated that chloride of lime eliminated the spread of contagious diseases by attacking the miasmas associated with them. The letter also made reference to the destruction of certain “viruses” that may have been responsible for transmission of the diseases.
Commentary: Averill’s letter is an extraordinary document that is worth reading. He was far ahead of his time. Indeed, he preceded Dr. John Snow’s conclusions about cholera transmission (1849) by 17 years.
