Alessandro Volta an early electric battery, which produced a steady electric current. Volta had determined that the most effective pair of dissimilar metals to produce electricity was zinc and copper. Initially he experimented with individual cells in series, each cell being a wine goblet filled with brine into which the two dissimilar electrodes were dipped. The voltaic pile replaced the goblets with cardboard soaked in brine. In announcing his discovery of the voltaic pile, Volta paid tribute to the influences of William Nicholson, Tiberius Cavallo, and Abraham Bennet. The battery made by Volta is credited as one of the first electrochemical cells.
Bust of Alessandro Peretti di Montalto Bust of Alessandro Peretti di Montalto The Bust of Alessandro Peretti di Montalto is a portrait sculpture by the Italian artist Gian Lorenzo Bernini.
