Robert Fulton (November 14, 1765 â February 24, 1815) was an American engineer and inventor who is widely credited with developing a commercially successful steamboat called Clermont. That steamboat went with passengers from New York City to Albany and back again, a round trip of 300 miles, in 62 hours in 1807.
In 1606, de Ayanz registered the first patent for a machine that used steam power to propel water from mines. The Spanish inventor â who is also credited with inventing one of the world's first air conditioning systems â used his steam engine to remove water from silver mines in Guadalcanal, Seville. While the Spaniard first patented a steam-operated machine for use in mining, an Englishman is usually credited with inventing the first steam engine. In 1698, Thomas Savery, an engineer and inventor, patented a machine that could effectively draw water from flooded mines using steam pressure.
