1807: Robert Fulton's North River Steamboat leaves New York City for Albany, New York, on the Hudson River, inaugurating the first commercial steamboat service in the world.
1927: Mathematician Erik Ivar Fredholm dies. He introduced and analyzed a class of integral equations now called Fredholm equations. Fredholm's work on integral equations and operator theory anticipated the theory of Hilbert spaces.
