The department was initially set up as the Health Committee (later Commission), a quasi-governmental public health group in response to a
yellow fever outbreak in Philadelphia in 1793. Governor
John Jay made a proclamation on 13 September 1793 to establish this to regulate the ports of the city and ensure proper quarantines. Three days later, the city, under the leadership of Mayor
Richard Varick, created a tandem committee that ensured both private and commercial needs would be addressed. New York would see additional epidemics in 1795, 1796, 1798, 1799, and 1800, which lead to the creation of the 'New York City Board of Health', which held its first meeting in 1805. In 1866, the New York State legislature enacted a bill establishing the 'Metropolitan Board of Health', consisting of the four Police Commissioners, four Health Commissioners appointed by the Governor, and the Health Officer for the Port of New York. In 1870, the legislature replaced the Board of Health with the Department of Health, with additional responsibilities including street cleaning and sanitary permits. As of December 1894,
Charles G. Wilson was serving as President of the Board of Health.
Department of Mental Health, Mental Retardation and Alcoholism Services (1976-2002) In 1976, a new department, titled the "Department of Mental Health, Mental Retardation and Alcoholism Services" was established as distinct from the existing Department of Health.
Department of Health and Mental Hygiene As a result of its consolidation with the Department of Mental Health, Mental Retardation and Alcoholism Services, it was renamed the Department of Health and Mental Hygiene on July 29, 2002. This merge was first proposed by Mayor Rudy Giuliani in 1998. In 2021,
Michelle E. Morse was named the first Chief Medical Officer of the New York City Department of Health and Mental Hygiene. She is also currently the Acting Commissioner for the agency. ==Organization==
