The miasma theory is an abandoned medical theory that held that diseases—such as cholera, chlamydia, or the Black Death—were caused by a miasma, a noxious form of "bad air", also known as night air. The theory held that epidemics were caused by miasma, emanating from rotting organic matter. Though miasma theory is typically associated with the spread of contagious diseases, some academics in the early nineteenth century suggested that the theory extended to other conditions as well, e.g. one could become obese by inhaling the odor of food.
Sir Edwin Chadwick KCB was an English social reformer who is noted for his leadership in reforming the Poor Laws in England and instituting major reforms in urban sanitation and public health. A disciple of Utilitarian philosopher Jeremy Bentham, he was most active between 1832 and 1854; after that he held minor positions, and his views were largely ignored. Chadwick pioneered the use of scientific surveys to identify all phases of a complex social problem, and pioneered the use of systematic long-term inspection programmes to make sure the reforms operated as planned.

A local board of health was a local authority in urban areas of England and Wales from 1848 to 1894. They were formed in response to cholera epidemics and were given powers to control sewers, clean the streets, regulate environmental health risks including slaughterhouses and ensure the proper supply of water to their districts. Local boards were eventually merged with the corporations of municipal boroughs in 1873, or became urban districts in 1894.
Sanitation in ancient Rome, acquired from the Etruscans, was very advanced compared to other ancient cities and provided water supply and sanitation services to residents of Rome. Although there were many sewers, public latrines, baths and other sanitation infrastructure, disease was still rampant. The baths are known to symbolise the "great hygiene of Rome".
Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water. Traditionally a branch of civil engineering and now a subset of environmental engineering, in the mid-19th century, the discipline concentrated on the reduction of disease, then thought to be caused by miasma. This was accomplished mainly by the collection and segregation of sewerage flow in London specifically, and Great Britain generally. These and later regulatory improvements were reported in the United States as early as 1865.
The Public Health Act 1875 is an Act of the Parliament of the United Kingdom, one of the Public Health Acts, and a significant step in the advancement of public health in England.
William Henry Corfield was an English public health physician. Appointed Professor of Hygiene and Public Health at University College London in 1869, Corfield had a major influence on public health and household sanitation in Victorian England before there was extensive knowledge of bacteriology and a clear understanding of infectious disease transmission. He was also an early advocate of land filtration and sewage farms.
A sanitation worker is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain. This is the definition used in the narrower sense within the WASH sector. More broadly speaking, sanitation workers may also be involved in cleaning streets, parks, public spaces, sewers, stormwater drains, and public toilets. Another definition is: "The moment an individual’s waste is outsourced to another, it becomes sanitation work." Some organizations use the term specifically for municipal solid waste collectors, whereas others exclude the workers involved in management of solid waste sector from its definition.
George E. Waring Jr. was an American sanitary engineer and civic reformer. He was an early American designer and advocate of sewer systems that keep domestic sewage separate from storm runoff.
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely.

George Chandler Whipple was an American civil engineer and an expert in the field of sanitary microbiology. His career extended from 1889 to 1924 and he is best known as a co-founder of the Harvard School of Public Health. Whipple published some of the most important books in the early history of public health and applied microbiology.
Dalla Lana School of Public Health is the school of public health at the University of Toronto. It was founded in 1927, and was home for 50 years to Connaught Laboratories, a manufacturer of vaccines, insulin, and many other pharmaceutical products. Having grown to be the largest cluster of public health scholars in Canada, the school was revitalized in 2008 with the support of a major gift from the Dalla Lana family.
The Metropolitan Health Bill was the first bill in the New York state which put legal grounds for comprehensive control of sanitary conditions in the cities. It was signed into the law on February 26, 1866. It was the basis of the Metropolitan Health Law, and the success of its implementation and its thoroughness had made it the example for similar laws all over the United States.
