Volta's pile, the first battery
For the first time, current flows through a wire steadily

Alessandro Volta stacked discs of zinc and copper separated by brine-soaked card and got a steady current. He reported the battery to the Royal Society in London in 1800; the unit of voltage, the volt, is named after him.
