Three men have a real claim to having discovered surgical anesthesia, and medical history has never fully settled among them. The public credit went, and largely still goes, to William Morton, a Boston dentist whose ether demonstration at Massachusetts General Hospital on October 16, 1846, in the room since nicknamed the Ether Dome, is the single most reproduced image in the history of the practice: a patient rendered insensible, a tumor removed from his jaw without a cry, and a surgeon turning to the assembled crowd to declare, gentlemen, this is no humbug.
But the demonstration that made anesthesia famous was not the first use of it. Crawford Long, a physician practicing in rural Georgia, had removed a tumor from a patient's neck under ether in March 1842, four full years before Morton, using a gas he had already watched partygoers inhale recreationally at so-called ether frolics. Long simply did not publish his results until 1849, by which point Morton had already taken the public credit, and the priority claim Long left behind is exactly as strong on the facts and exactly as invisible in the popular memory of the discovery.
Horace Wells, a Hartford dentist and Morton's own former business partner, has the third claim, and the saddest one. Wells had begun using nitrous oxide in his own dental practice in 1844 and attempted a public demonstration at Massachusetts General Hospital in January 1845, a full year before Morton, using a patient who cried out during the procedure. The demonstration was judged a failure on the spot, Wells was humiliated in front of the same institution Morton would later triumph in, and his subsequent life, a collapsed practice, self-experimentation with anesthetic gases, and death by his own hand in 1848, reads now as a case study in how thin the line between the credited discoverer and the forgotten one can be.
The dispute over who deserves the credit was bitter in its own time, Morton spent years and a fortune trying to patent and monetize his ether preparation, litigating against Wells, Long and the chemist Charles Jackson who had originally suggested ether to him, and it remains genuinely open among historians rather than settled by later consensus. What is not in dispute is the effect: within months of Morton's demonstration, ether anesthesia had crossed the Atlantic and begun to remake surgery from a desperate, restrained-patient ordeal into a procedure a patient could survive unconscious, the foundation on which the entire modern practice of surgery would be built.
