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)

Medical Eponyms
John Snow Silver Medal (1946)
The John Snow Silver Medal was originally given to anaesthetists who had distinguished themselves and received awards for gallantry in the Second World War.
In 1946 the first three recipients were the founder of the Association of Anaesthetists, Henry W Featherstone OBE; Leslie G Morrison MC; and Professor Edgar Alexander Pask OBE.
Now awarded to UK and Irish anaesthetists who have held high office in, and provided exceptional service to the Association; or eminent UK and Irish anaesthetists of great distinction
Key Medical Attributions
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.
