What did William Farr discover?
Farr developed a classification of causes of death, constructed the first English life table, and made major contributions to occupational epidemiology, comparing mortality in specific occupations with that of the general population.

The theory of zymotic disease was Farr’s contribution to the debate on aetiology. He identified urbanisation and population density as public health issues. In terms of nosology he classed epidemic, endemic and contagious diseases as “zymotic”, seen as diseases of filth and overcrowding.
What did William Farr contribute to epidemiology?
William Farr’s contributions to epidemiology were both broad and deep.

Farr fully co-operated with Snow’s efforts to test his theory, giving Snow unpublished material from the death registers, and, when Snow’s preliminary results appeared promising, ordered local registrars in South London to inquire into the source of water, when a cholera death was registered [1l, 19e].

How did Henry Whitehead help John Snow?
Snow’s work — and Whitehead’s own investigations — convinced Whitehead that the Broad Street pump was the source of the local infections. Whitehead then joined with Snow in tracking the contamination to a cesspool that leaked into the water table which led to the outbreak’s index case.
Who is known as father of public health?
Public Health and Modern.
What was the final piece of the mystery that Henry Whitehead discovered?
Whitehead discovered that baby Frances had gotten sick before the outbreak of cholera started and that her mother disposed of her feces in a cesspool that was “just steps away from the Broad Street pump” (46).

Thereafter she emptied the pails in the cesspool opening in front of her house. Likely baby Lewis had Vibrio cholerae which contaminated the napkin used to absorb diarrhea.
