Why it matters
The opening date marks Morton’s public ether demonstration at Massachusetts General Hospital on 16 October 1846, during an operation by John Collins Warren. It is a milestone in dissemination, not a claim that all anesthesia began that day.
University of Texas Medical Branch: William T. G. Morton ↗Crawford Long had used ether during an operation in Georgia on 30 March 1842. His work predates the Boston demonstration and helps explain why priority and public recognition became separate historical questions.
Georgia Historical Society: Crawford Long and anesthesia ↗Anesthesia and antisepsis addressed different obstacles. Patients could survive an operation yet die from infection. Lister’s work in the 1860s applied ideas about microorganisms to surgical practice, developing procedures intended to reduce infection.
Royal College of Surgeons: Lister in the archives ↗The endpoint marks the rabies vaccination of Joseph Meister after a dog bite in July 1885. Pasteur worked with medical collaborators, including Jacques Joseph Grancher. This was a specific milestone in rabies prevention, not the beginning of vaccination as a whole.
