Chauncey Street Unlike most military heroes honored with street names in Brooklyn, Isaac Chauncey (1772-1840) actually had a connection to the County of Kings. After time spent in naval operations in China and the Mediterranean, Chauncey returned to the United States to take command over the Brooklyn Navy Yard. He remained there until the War of 1812, when he was dispatched to the Great Lakes to oversee America’s naval forces. Chauncey later returned to Brooklyn to once again direct the Brooklyn Navy Yard, this time for nearly a decade.

In hindsight, there was much they did not see: they were a block from Chauncey Street, nicknamed “Chancy” among neighbors, where a police officer is parked 24 hours a day to deter gunfights. A woman who lives nearby giggled as she recalled a recent morning when she was late to work because there were too many bullets flying to cross Chauncey.
