William H. Hill
Hill liked to be known as a "River-Man," and is most associated with both walking a tightrope over Niagra Falls and riding in barrel over the falls.
He assisted famed Niagra Falls daredevil Jean Lussier who went over the falls in a giant rubber ball in 1928 by recovering the ball below the rapids.
Hill attempted his own feat to "shoot the rapids" below in falls in a barrel in 1931 with limited success. Saved from a whirlpool by his son, William Hill, Jr., the younger Hill was to go on to attempt to go over the falls himself in 1951 with fatal result.
