hiphotos009459 Alessandro Volta (1745-1827) Italian physicist. On the table are two of his inventions, the Voltaic pile (wet battery) on the left, and the electrophorus, an apparatus demonstrating electrostatic charge by induction. His name is given to the unit of electromotive force, the volt.//

hiphotos014459 Alessandro Volta's wet pile or battery, 1800. Italian physicist Volta (1745-1827) was the inventor of the voltaic pile, an early battery and the first source of current electricity. This consisted of two different metals, separated by chemicals in order to enable a flow of electricity. In 1775, he invented the electrophorus, a precursor of the induction machine, and in 1777 he invented an 'inflammable air' electric pistol. The unit of electromotive force 'volt' is named after him. From Volta's paper published in Philosophical Transactions of the Royal Society, London, 1800.//

hiphotos015091 Voltaic battery (pile), 1887. A battery of the type invented by Italian physicist Alessandro Volta (1745-1827). It consists of a disc of zinc, a disc of copper, a disc of cloth moistened with acid, then a disc of zinc and so on. Each contact between zinc and copper formed a 'couple'. From Natural Philosophy by A Ganot. (London, 1887).//
