Designed by Dr John Snow (1813–1858), an English doctor who led the early development of anaesthetics, this facemask and breathing tube apparatus were used to administer the anaesthetic drug ether.
Snow had observed that the success rates of using ether during operations were variable. His inhaler was designed to regulate the temperature and concentration of the ether used, resulting in more effective anaesthesia.
