He was Mayor of New York City from 1829 to 1833. Faced with reports of cholera in neighboring towns in 1832, he implemented a strict quarantine policy, regulating travel to and from New York City, and restricting ships to a distance of 300 yd (270 m) from port, and carriages from within 1.5 mi (2.4 km) of the city. His attempt to prevent an epidemic failed [3]- because it was based on the mistaken but then-accepted notion that transmission of cholera was through personal contact rather than through contaminated water and food, The actual means of transmission was not discovered until 1883.
