Riverdale (population 47,850 as of the 2000 U.S. Census) is an affluent and upper middle class residential neighborhood in the northwest portion of the Bronx, a borough in New York City. Riverdale contains the northernmost point in New York City. In 1642, Anthony Van Corlaer died while attempting to swim across the Hudson from Spuyten Duyvil in Riverdale.[2] A witness to Van Corlaer's death stated that "the devil" in the shape of a giant fish swam up and proceeded to "seize the sturdy Anthony by the leg and drag him beneath the waves."[3] This may be the earliest recorded shark attack in the New World.[3] In the late 17th century, Frederick Philipse, the lord of Philipse Manor in Westchester County, received permission to construct a bridge across Spuyten Duyvil Creek and charge tolls. "King's Bridge", which was located roughly south of and parallel to where West 230th Street lies today, opened in 1693.[4]
