Minneapolis was destined to be a center of commerce due to its location at the Falls of St. Anthony, which was named by the French explorer Fr. Louis Hennepin in 1680. St. Anthony Falls is by far the largest source of water power on the Mississippi River. The falls were harnessed to power lumber mills in the 1840s and later for flour milling. By 1870, Minneapolis on the west bank and St. Anthony on the east bank formed the largest flour producing center in the world.
