Luigi Galvani (/ ɡælˈvɑːni /, also US: / ɡɑːl -/; [1][2][3][4] Italian: [luˈiːdʒi ɡalˈvaːni]; Latin: Aloysius Galvanus; 9 September 1737 – 4 December 1798) was an Italian physician, physicist, biologist and philosopher, who studied animal electricity. In 1780, he discovered that the muscles of dead frogs' legs twitched when ...
Galvanism: electrodes touch a frog, and the legs twitch into the upward position [1] Galvanism is a term invented by the late 18th-century physicist and chemist Alessandro Volta to refer to the generation of electric current by chemical action. [2] The term also came to refer to the discoveries of its namesake, Luigi Galvani, specifically the ...
Galvanic cell. Galvanic cell with no cation flow. A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions. A common apparatus generally consists of two different metals, each ...
Frog galvanoscope. Frog's-leg galvanoscope. The frog galvanoscope was a sensitive electrical instrument used to detect voltage [1] in the late 18th and 19th centuries. It consists of a skinned frog's leg with electrical connections to a nerve. The instrument was invented by Luigi Galvani and improved by Carlo Matteucci.
Based on some findings by Luigi Galvani, Alessandro Volta, a friend and fellow scientist, believed observed electrical phenomena were caused by two different metals joined by a moist intermediary. He verified this hypothesis through experiments and published the results in 1791.
Volta's invention was built on Luigi Galvani's 1780s discovery that a circuit of two metals and a frog's leg can cause the frog's leg to respond. [1] Volta demonstrated in 1794 that when two metals and brine-soaked cloth or cardboard are arranged in a circuit they too produce an electric current.
17 January 1834. (1834-01-17) (aged 71) Alma mater. University of Bologna. Giovanni Aldini (10 April 1762 – 17 January 1834) [1] was an Italian physician [2] and physicist born in Bologna. He was a brother of the statesman Count Antonio Aldini (1756–1826). He graduated in physics at University of Bologna in 1782.
The studies by Williamson, Walsh, and Hunter appear to have influenced the thinking of Luigi Galvani and Alessandro Volta – the founders of electrophysiology and electrochemistry.
