The Polhemus Memorial Clinic in Cobble Hill, Brooklyn, New York City was built in 1897 as an extension of a hospital for the poor on the corner of Henry and Amity streets. It was officially inaugurated January 5, 1898. Throughout most of its lifetime, 1897 to July 2008, it was part of the Long Island College Hospital (LICH). Joseph Korom, the author of The American Skyscraper (2008), considers the eight-story tower to be the first skyscraper hospital ever built. The clinic and adjacent row houses were designated part of the Cobble Hill Historic District in 1988.
