The Wood Library Museum of Anesthesiology presents a timeline of the history of anaesthesia for the American Society of Anesthetists.
William T Morton gave the first successful demonstration of ether anaesthesia at the Massachusetts General Hospital in 1846.
Less than a year later, William Russ Pugh did the same in Tasmania.
John Belisario, a dentist, also performed many anaesthetics in 1947 in Sydney.
These dates mark the beginning of extraordinary developments that led to what we know as modern anaesthesia.
