In 1844, Thomas Clyde partnered with British-based Swedish inventor John Ericsson to apply his screw-propeller to steam vessels.
After several experimental versions, Clyde launched the twin-screw propeller steamer John S. McKim making it the first screw steamer built in the United States for commercial use.
