About this date

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.

About credit

Priority was fiercely disputed, with several claimants. Long, Morton and Horace Wells all have a claim.

Chapter I

The world before

Life before Anaesthesia

Patients were held down while surgeons worked as fast as they could. Many refused operations because of the pain.

The human achievement

How it came about

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

How it works

Anaesthesia, explained in two steps.

Step 01 of 02

Blocking pain

Ether depresses the nervous system so the patient does not feel or remember the operation.

IV

The transformation

What changed for humanity

  1. Surgery

    Complex operations in the abdomen and chest became feasible.

  2. Childbirth

    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

Life before and after Anaesthesia

Before

Awake, held down, a few minutes.

After

Unconscious and painless.

Anaesthesia

  • Beyond the collection

    Antiseptic surgery

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

  • Beyond the collection

    Modern anaesthesia

    Drugs are now monitored by dedicated specialists.

Human stories

The people and the moments

The Ether Dome

The operating theatre where Morton demonstrated ether is still preserved at Massachusetts General Hospital and is known as the Ether Dome.

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