of dry pile is the Zamboni pile. Francis Ronalds in 1814 was one of the first to realize that dry piles also worked through chemical reaction rather than metal-to-metal contact, even though corrosion was not visible due to the very small currents generated. The dry pile could be referred to as the ancestor of the modern dry cell.
