The first public demonstration of surgical anesthesia, at the Massachusetts General Hospital, October 16, 1846. Various anesthetics, from alcohol to opium, were used through history, but it was not until 1846 that a successful operation was demonstrated to the public and an account published. Administering ether gas through the patient's mouth, was American dentist William T.G. Morton.(1819-1868). Some observers left the theater in disgust, believing the demonstration to be a sham.
