Jonathan Mason Warren, MD, was an MGH surgeon best known for his work in reconstructive surgery. He was present at the first successful public demonstration of surgical anesthesia in the Ether Dome in 1846 and is believed to have been the first to administer ether to a child. Warren’s family had close ties to the hospital — his father was MGH cofounder John Collins Warren, MD — and his wedding clothes are preserved here. Since the average man of British descent at the time was about 5’8,” these clothes indicate that Warren was short for his day as well as ours.
