Sir John Simon

Died 23 Jul 1904 at age 87 (born 10 Oct 1816).English pathologist, whose sanitary reforms led to modern standards of public health. In 1850, Simon joined with the new Epidemiological Society, which in 1853 published a report which was submitted to Parliament, calling for compulsory smallpox vaccination of all infants. He also recognized that outside and home employment of mothers is a factor in infant mortality; in 1856 he stated that "infants perish under the neglect and mismanagement that their mothers' occupation implies." With the passing of the Public Health Act of 1848, local boards of health were set up, responsible for drainage, paving, cleansing and an ample supply of water. Simon described the improvements in English Sanitary Institutions, 1890. He was knighted in 1887.
