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.
Abraham Bennet Abraham Bennet Abraham Bennet FRS (baptised 20 December 1749 - buried 9 May 1799) was an English clergyman and physicist, the inventor of the gold-leaf electroscope and developer of an improved magnetometer. Though he was cited by Alessandro Volta as a key influence on his own work, Bennet's work was curtailed by the political turbulence of his time. Abraham was baptised in Taxal, Derbyshire, the son of another Abraham Bennet, a schoolmaster, and his wife Ann "née" Fallowes. There is no record of him having attended university but he is recorded as a teacher at Wirksworth Grammar School as "MA".
