Snow suffered a stroke while working in his London office on 10 June 1858. He was 45 years old at the time. He never recovered, dying six days later on 16 June 1858. He was buried in Brompton Cemetery. It has been speculated that his premature death may have been related to his frequent exposure and experimentation with anesthetic gases, which is now known to have numerous adverse health effects. Snow administered and experimented with ether, chloroform, ethyl nitrate, carbon disulfide, benzene, bromoform, ethyl bromide and dichloroethane during his lifetime. Legacy and honours A plaque commemorates Snow and his 1854 study in the place of the water pump on Broad Street (now Broadwick Street). It shows a water pump with its handle removed. The spot where the pump stood is covered with red granite. A public house nearby was named "The John Snow" in his honour. The John Snow Society is named in his honour, and the society regularly meets at The John Snow pub. An annual Pumphandle Lecture is delivered each September by a leading authority in contemporary public health. His grave in Brompton Cemetery, London, is marked by a funerary monument. In York a blue plaque on the west end of the Park Inn, a hotel in North Street, commemorates John Snow. Together with fellow pioneer of anaesthesia Joseph Thomas Clover, Snow is one of the heraldic supporters of the Royal College of Anaesthetists. The Association of Anaesthetists of Great Britain and Ireland awards The John Snow Award, a bursary for undergraduate medical students undertaking research in the field of anaesthesia. Despite reports that Snow was awarded a prize by the Institut de France for his 1849 essay on cholera, a 1950 letter from the Institut indicates that he received only a nomination for it. In 1978 a public health research and consulting firm, John Snow, Inc, was founded. In 2001 the John Snow College was founded on the University of Durham's Queen's Campus in Stockton-on-Tees. In 2009, the John Snow lecture theatre was opened by Anne, Princess Royal, at the London School of Hygiene & Tropical Medicine. In 2013 The Lancet printed a correction of its brief obituary of Snow, originally published in 1858: "The journal accepts that some readers may wrongly have inferred that The Lancet failed to recognise Dr Snow's remarkable achievements in the field of epidemiology and, in particular, his visionary work in deducing
