Horace Wells was an American dentist who pioneered the use of anaesthesia in dentistry, specifically nitrous oxide (or laughing gas). Born in Vermont, Wells was educated in Walpole, New Hampshire before studying dentistry in Boston. After obtaining a degree, Wells set up a practice in Hartford, Connecticut, with an associate named William T.G. Morton, who would become famous for his use of ether as an anesthesia on October 18, 1846. Wikipedia
