A person who administers ether as an anesthetic; a device for vaporizing or dispersing ether.
From 'etherize' plus the agent suffix '-er' (one who does). A historical medical term for early anesthetists or the equipment they used.
The first etherizers were brave pioneers—they had to figure out the right dose by trial and error, knowing too little meant screaming pain and too much meant death, with no monitors to help them.
