Robert Fulton (November 14, 1765 – February 25, 1815) was an American engineer and inventor who is widely credited for developing a commercially successful steamboat; the first was called North River Steamboat (later Clermont). In 1807 that steamboat traveled on the Hudson River with passengers, from New York City to Albany and back again, a round trip of 300 miles (480 km), in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers.
