What happened
On October 16, 1846, in the surgical amphitheater on the fourth floor of the Bulfinch Building at Massachusetts General Hospital, the first successful public demonstration of ether for surgical anesthesia was performed. William T. G. Morton, a dentist, administered ether to the patient Edward Gilbert Abbott through an apparatus of a tube connected to a glass globe, so that the surgeon John Collins Warren could remove a tumor from Abbott's neck. During the operation the patient did not shrink or cry out from pain; afterward he reported feeling only something like scraping with a blunt instrument. A plaque in the room, now called the Ether Dome, records that this was the first public demonstration of anesthesia to the extent of producing insensibility to pain during a serious surgical operation.
Why it matters
Before anesthesia, surgery was a race against agony, and its speed and scope were limited by how much pain a conscious patient could endure. Ether removed that limit and transformed surgery from a last-resort ordeal into a controlled procedure, marking the birth of anesthesiology and opening the door to the longer, more careful operations modern medicine depends on.
How we know
The demonstration is documented by the operating-day surgical records preserved from Massachusetts General Hospital and by the hospital's own historical account of the event and the Ether Dome where it took place.
