John Snow
John Snow (1813-1858) was an English physician.
Snow is considered one of the fathers of modern epidemiology (the cholera cartographer); and a leader in the development of anaesthesia, medical hygiene and public health.
Developed the first staging classification for depth of anaesthesia in 1847, the five stages of narcotism or etherization as a precursor to classifications by Plomley and Guedel (1937)

Anaesthesia
The first classification system for general anaesthesia was proposed in 1847 by John Snow as the 5 stages of etherization (narcotism); and furthered by Francis Plomley in the Lancet in the same year. Guedel later proposed a four stage classification system to assess the depth of general anesthesia in 1937. This was designed for use with a single inhalational anesthetic agent (ether), in patients premedicated with morphine and atropine.
