The Electric Battery (Voltaic Pile)
The voltaic pile stacked alternating metal discs with brine-soaked separators to produce the first continuous electric current, launching the practical study and use of electricity.
Attribution — A single person is the clear, well-documented originator — uncommon in technology.
Alessandro Volta is the clear inventor of the pile (1800). It grew out of his dispute with Luigi Galvani over 'animal electricity' — Volta showed the effect came from the dissimilar metals, not the tissue.
What counts as the invention: Volta's invention (the battery) is distinct from Galvani's earlier discovery of bioelectric phenomena that prompted it.
Contributors
Historical impact
A steady current made electrochemistry, electromagnetism, telegraphy, and electroplating possible.
Modern relevance
Every battery, from a remote control to an electric car, is a descendant of the voltaic pile.
