Answer:
Americans remember Robert Fulton for building a steamboat.
Explanation:
Robert Fulton was an American engineer, entrepreneur and inventor, known for developing the first steamboat, which became a commercial success.
In 1807, with his steam-powered ship called Clermont, he made a 400-kilometer journey along the Hudson River, from New York to Albany. Without being the inventor of steam navigation, Fulton gave it the final boost by making it functional and economically viable. Previously, in 1800, he had designed the first propeller submarine, the Nautilus.
