Blackwell House is a historic house on Roosevelt Island in New York City. The house's name comes from Jacob Blackwell, who built the house in 1796. He was the great-grandson of Robert Blackwell, who in 1686 took ownership of what was then known as Manning's Island and subsequently became the island's new namesake.^[2] The house was added to the National Register of Historic Places in 1972.^[1]
