Commissioner of Health of the City of New York
The Commissioner of Health of the City of New York is the head of the city's Department of Health and Mental Hygiene. The commissioner is appointed by the Mayor of New York City, and also serves on the city's Board of Health with the chairperson of the Department's Mental Hygiene Advisory Board and nine other members appointed by the mayor.

History
The Metropolitan Board of Health, which was the predecessor agency to the Department of Health and consisted of sanitary and vital statistics bureaus, had its first meeting on March 5, 1866. The modern Department of Health, under a single commissioner, was formed by the New York City Charter revision pursuant to Chapter 137 of the Laws of 1870 passed by the New York State legislature. In the early years after its formation, commissioners were sometimes political appointments, with no experience in medicine or related fields. In 2002, the Department of Health was merged with the Department of Mental Health, Mental Retardation and Alcoholism Services to form the Department of Health and Mental Hygiene.

Qualifications
City regulations currently require that the commissioner of health must be a doctor of medicine, and have either
 an M.P.H. degree, an M.B.A. or M.P.A. degree with concentration in the health field, or an equivalent degree and at least five years' teaching experience college or university public health, or
