William T. G. Morton publicly demonstrated ether anaesthesia at Massachusetts General Hospital on 16 October 1846. Crawford Long had used ether in 1842 but did not publish until 1849.
Priority was fiercely disputed, with several claimants. Long, Morton and Horace Wells all have a claim.
The world before
Patients were held down while surgeons worked as fast as they could. Many refused operations because of the pain.
The human achievement
At the “Ether Dome” in Boston, Morton gave Gilbert Abbott ether while Warren removed a tumour from his neck. Word spread across Europe within months. Chloroform was soon used in childbirth, including by Queen Victoria in 1853.
Understanding the invention
Anaesthesia, explained in two steps.
Step 01 of 02
Ether depresses the nervous system so the patient does not feel or remember the operation.
IV
The transformation
Complex operations in the abdomen and chest became feasible.
Pain relief became available in labour.
Surgery no longer had to be done in seconds on screaming patients. Longer, more careful operations became possible.
Before and after
Before
Awake, held down, a few minutes.
After
Unconscious and painless.

Antiseptic surgery
Lister’s 1860s work made surgery safer from infection.

Modern anaesthesia
Drugs are now monitored by dedicated specialists.

Where accounts differ, this museum follows the documented record and says so.
