Volta, Alessandro, Conte

(älĕs-sän`drō kôn`tā vôl`tä), 1745–1827, Italian physicist. He was professor of physics at the Univ. of Pavia from 1779 and became famous for his work in electricity. Napoleon I made him a count and a senator of the kingdom of Lombardy. Volta invented the so-called Volta's pile (or voltaic pile); the electrophoruselectrophorus,
device used to generate static electric charges. It has two parts: a nonconducting plate (e.g., of hard rubber) that is negatively charged and a metal plate with an insulated handle.
