The discovery of anesthesia is considered one of medicine’s most important breakthroughs. Today’s sophisticated surgical procedures would not be possible without anesthesia. Hartford dentist, Horace Wells didn’t discover nitrous oxide, he was the first to discover its ability to allow practitioners to perform pain-free procedures. In collaboration with Hartford Stage, the Connecticut Historical Society has created a panel exhibit illustrated by artifacts from its collection that highlights some of the lesser-known aspects of Wells’s fascinating and unique story. Visitors to the Hartford Stage’s play Ether Dome will be able to learn more about Horace Wells and the history behind his breakthrough discovery.
