[17] Snow published an article on ether in 1847 entitled On the Inhalation of the Vapor of Ether. I had an interview with the Board of Guardians of St James's parish, on the evening of the 7th inst [7 September], and represented the above circumstances to them. John Snow, Father of Epidemiology A London physician by the name of John Snow mapped out the spread of a cholera outbreak in the city 150 years ago. He was especially interested in patients with respiratory diseases and tested his hypothesis through animal studies. [35], In 1830, Snow became a member of the temperance movement. From the last month of 1849 until late in 1853, Britain Dr. John Snow is famous for his investigations into the causes of the 19 th century cholera epidemics, and is also known as the father of (modern) epidemiology. Its opening was originally under a nearby house, which had been rebuilt farther away after a fire. He realised that chloroform was much more potent and required more attention and precision when administering it. The English physician and surgeon, John Snow, was experienced in the treatment of Cholera having treated many such patients and researching the disease at the Newcastle Infirmary. We were to choose one of these major discoveries and present their findings. [16], Snow's interest in anaesthesia and breathing was evident from 1841 and beginning in 1843, he experimented with ether to see its effects on respiration. Paper by Thomas Coleman: “John Snow, the London doctor often considered the father of modern epidemiology, analyzed 1849 and 1854 cholera mortality for a population of nearly half a million in South London. Dr. John Snow is now considered the Father of Epidemiology for finding the source of cholera over 150 years ago. John Snow (1813-1858) was a brilliant British physician. Dr. John Snow is famous for his investigations into the causes of the 19 th century cholera epidemics, and is also known as the father of (modern) epidemiology. His identification of the Broad Street pump as the cause of the Soho epidemic is considered the classic example of epidemiology. He showed that homes supplied by the Southwark and Vauxhall Waterworks Company, which was taking water from sewage-polluted sections of the Thames, had a cholera rate fourteen times that of those supplied by Lambeth Waterworks Company, which obtained water from the upriver, cleaner Seething Wells. Prior to his discoveries, there was little knowledge of how Cholera was spread, and thus, many people died unnecessarily within the crowded, unsanitary conditions of urban centers. He learned that [Article in Spanish] Cerda L J(1), Valdivia C G. Author information: (1)Departamento de Salud Pública, Facultad de Medicina, Pontificia Universidad Católica de Chile, Temuco, Chile. It seemed most likely to Snow ", Snow decided to publicize his views by giving lectures. testing the effects of precisely controlled doses of ether and chloroform on He treated 77 obstetric patients with chloroform. Admitted as a member of the Royal College of Surgeons of England on 2 May 1838, he graduated from the University of London in December 1844 and was admitted to the Royal College of Physicians in 1850. For other uses, see, Wedding Record of William Snow and Frances Empson, Huntington All Saints, 24 May 1812, Donaldson, L.J.

As more cases appeared, Snow began examining sick patients. [32] During the Annual Pumphandle Lecture in England, members of the John Snow Society remove and replace a pump handle to symbolise the continuing challenges for advances in public health. During his early years as an apprentice, he filled notebooks with his thoughts and observations on scientific subjects. This action has been commonly credited as ending the outbreak, but Snow observed that the epidemic may have already been in rapid decline: There is no doubt that the mortality was much diminished, as I said before, by the flight of the population, which commenced soon after the outbreak; but the attacks had so far diminished before the use of the water was stopped, that it is impossible to decide whether the well still contained the cholera poison in an active state, or whether, from some cause, the water had become free from it.
