Sewer Gas - History

History

During the mid 1800s, when indoor plumbing was being developed, it was believed by many that disease was spread by miasmas, or literally "bad air." Originally, traps in plumbing drain pipes were designed to help keep this bad air from passing back into living spaces within buildings. However, during the Broad Street cholera outbreak in London, in the Summer of 1854, physician John Snow, among others, worked to prove that polluted water was the culprit, not the foul smells from sewage pipes. Subsequently, even as the Germ theory of disease developed, society was slow to accept the idea that odors from sewers were relatively harmless when it came to the spread of disease.

Famous quotes containing the word history:

    [Men say:] “Don’t you know that we are your natural protectors?” But what is a woman afraid of on a lonely road after dark? The bears and wolves are all gone; there is nothing to be afraid of now but our natural protectors.
    Frances A. Griffin, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 19, by Susan B. Anthony and Ida Husted Harper (1902)

    It takes a great deal of history to produce a little literature.
    Henry James (1843–1916)

    In history the great moment is, when the savage is just ceasing to be a savage, with all his hairy Pelasgic strength directed on his opening sense of beauty;—and you have Pericles and Phidias,—and not yet passed over into the Corinthian civility. Everything good in nature and in the world is in that moment of transition, when the swarthy juices still flow plentifully from nature, but their astrigency or acridity is got out by ethics and humanity.
    Ralph Waldo Emerson (1803–1882)
