Chadwick: Report on the Sanitary Condition of the Labouring Population of Great Britain

1842 Life and health institution

Share

A report on the sanitary condition of the labouring population of Great Britain of 1842, which linked epidemic diseases to 'atmospheric impurities produced by decomposing animal and vegetable substances, by damp and filth, and close and overcrowded dwellings' and demanded drainage, removal of refuse and better water supply.

Its author, the English lawyer and civil servant Edwin Chadwick, was a committed miasmatist (his formula: 'all smell is disease'), and the programme of sewerage and piped water grew precisely out of the belief in contagious smell.

The reform worked because removing sewage and supplying clean water interrupted the waterborne route of cholera and typhoid, that is, for a reason the theory itself did not foresee. Hamlin (1998) shows that the 'sanitary idea' additionally pushed poverty and hunger out of the explanation.

What it grew from

• "Airs, Waters, Places": disease from air, waters and locality

  influenced · Confidence: high

  Chadwick's sanitary reform grew out of the miasma theory: the conviction that disease comes from smell and filth produced the programme of drainage and sewerage.

  Dispute: "It worked for the wrong reason": Hempel puts it plainly: "The government was doing the right thing, albeit for the wrong reasons". Hamlin (1998) complicates this: Chadwick was not merely wrong about etiology but deliberately narrowed the explanation to "filth", excluding poverty and hunger (Corbett: "argued that the primary cause of pauperism and misery was not poverty or rampant capitalism, but filth"). Halliday adds that Chadwick's early flushing of sewage into the Thames may have intensified the cholera epidemics of 1848-1849 and 1853-1854 (full text of the article unavailable; the thesis is taken from its introduction and its well-known argument; needs checking).

  parallel to · Confidence: medium

  The sources confirm that both were miasmatists of the same sanitary movement; the independence of their programmes and the absence of influence between them are not documented.

  Nightingale and Chadwick independently developed the same miasmatic programme of hygiene (air, cleanliness, drainage).

  Dispute: No historian has been found who asserts a direct influence of Chadwick on Nightingale: they worked within the same sanitary movement and knew each other, but the influence itself is not documented.
