I recently discovered that Jules Verne's Nautilus (1875) was named after the "first practical submarine", designed and built by Robert Fulton (later a steamboat designer) and first tested in 1800. Fulton built the submarine as a delivery device for the torpedoes he also invented, and tried to sell the weapons system to Napoleon to counter the dominant British fleet. So while Verne is one of the great scifi inventors of all time, his submarine was an homage to an older invention, dialed up to eleven. I wonder if there is another timeline somewhere of inventions that no science fiction story ever anticipated. It may be a shorter list.
