August 17, 1807 - For the first time in the world, steamships were put into commercial use as ferries in New York City, USA.

In 1807, he built the wheeled "Phoenix" ship "Phoenix" from the coast of New York to Philadelphia for a trial flight, on the way to the storm "Clemont" ship but after 13 days of sailing still peacefully arrived in Philadelphia, this is the world's first ship sailed by sea.
