Inventors
Alessandro Volta
1745–1827 · Maker of continuous current
Italy
Galvani’s frogs twitched. Volta stacked metals and brine and drew a steady current without an animal. The pile is a chemical reactor you can hold. Every later battery is a conversation with that stack — including the one in your phone.
Why it mattered
- Gave laboratories a current that lasted.
- Opened electrolysis, telegraph, and the electrical century.
