In 1807, he and Robert R. Livingston built the first commercially successful steamboat, North River Steamboat (later known as Clermont). Livingston's shipping company began using it to carry passengers between New York City and up the Hudson River to the state capital Albany. Clermont made the 150-mile (240 km) trip in 32 hours. Passengers on the maiden voyage included a lawyer Jones and his family from Bethlehem, Pennsylvania. His infant daughter Alexandra Jones later served as a Union nurse on a steamboat hospital in the American Civil War.
