Fulton died in 1815 in New York City from tuberculosis (then known as "consumption"). He had been walking home on the frozen Hudson River when one of his friends, Addis Emmet, fell through the ice. In the attempt to rescue his friend, Fulton got soaked with icy water. He is believed to have contracted pneumonia. When he got home, his sickness worsened. He was diagnosed with consumption and died at 49 years old. After his death, his widow remarried to Charles Augustus Dale on November 26, 1816. His descendants include Cory Lidle, a former Major League Baseball pitcher.
