Luigi Galvani ( / ɡ æ l ˈ v ɑː n i / , also US : / ɡ ɑː l -/ ; 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, using a frog, he discovered that the muscles of dead frogs' legs twitched when struck by an electrical spark. This was an early study of bioelectricity , following experiments by John Walsh and Hugh Williamson .

13-421: Galvanic (after Luigi Galvani ) may refer to: Galvanic anode Galvanic bath Galvanic cell Galvanic corrosion Galvanic current Galvanic isolation Galvanic potential Galvanic series Galvanic skin response Galvanic vestibular stimulation Galvanism Galvanization Operation Galvanic, World War II attack which included

26-454: A cell potential ; biological electricity has the same chemical underpinnings as the current between electrochemical cells , and thus can be duplicated outside the body. Volta's intuition was correct. Volta, essentially, objected to Galvani’s conclusions about "animal electric fluid", but the two scientists disagreed respectfully and Volta coined the term "Galvanism" for a direct current of electricity produced by chemical action. Since Galvani

The house in which he was born may still be seen on Via Marconi, 25, in the center of Bologna. Domenico was a goldsmith . His family had produced several illustrious men. Galvani then began taking an interest in

65-493: The University of Pavia , was among the first scientists who repeated and checked Galvani’s experiments. At first, he embraced animal electricity. However, he started to doubt that the conductions were caused by specific electricity intrinsic to the animal's legs or other body parts. Volta believed that the contractions depended on the metal cable Galvani used to connect the nerves and muscles in his experiments. Every cell has

78-462: The 18th century by the scientific community. In recognition of his merits, the emperor of Austria made him a Knight of the Iron Crown and a councillor of state at Milan , where he died. He bequeathed a considerable sum to found a school of natural science for artisans at Bologna. Aldini's most famous public demonstration of the electro-stimulation technique of deceased limbs was performed on

91-462: The executed criminal George Forster at Newgate in London in 1803. The Newgate Calendar describes what happened when the galvanic process was used on the body: On the first application of the process to the face, the jaws of the deceased criminal began to quiver, and the adjoining muscles were horribly contorted, and one eye was actually opened. In the subsequent part of the process the right hand

104-408: The field of "medical electricity". This field emerged in the middle of the 18th century, following electrical researches and the discovery of the effects of electricity on the human body by scientists including Bertrand Bajon and Ramón M. Termeyer  [ pl ] in the 1760s, and by John Walsh and Hugh Williamson in the 1770s. Alessandro Volta , a professor of experimental physics in

117-461: The new authority. Galvani, who disagreed with the social and political confusion, refused to swear loyalty, along with other colleagues. This led to the new authority depriving him of all his academic and public positions, which took every financial support away. Galvani died peacefully surrounded by his mother and father, in his brother’s house depressed and in poverty, on 4 December 1798. Galvani's legacy includes: Galvani, according to William Fox,

130-434: Was "by nature courageous and religious." Jean-Louis-Marc Alibert said of Galvani that he never ended his lessons “without exhorting his hearers and leading them back to the idea of that eternal Providence, which develops, conserves, and circulates life among so many diverse beings.” Giovanni Aldini Giovanni Aldini (10 April 1762 – 17 January 1834) was an Italian physician and physicist born in Bologna . He

143-712: Was a brother of the statesman Count Antonio Aldini (1756–1826). He graduated in physics at University of Bologna in 1782. He became professor of experimental physics at University of Bologna in 1798, in succession to his uncle Luigi Galvani (1737–1798). His scientific work was chiefly concerned with galvanism , anatomy and its medical applications, with the construction and illumination of lighthouses , and with experiments for preserving human life and material objects from destruction by fire. He wrote in French and English in addition to his native Italian, and in Latin, still used in

156-504: Was raised and clenched, and the legs and thighs were set in motion. Mary Shelley (born Mary Godwin 30 August 1797) would have been only 5 years old in January 1803 when Aldini experimented on the corpse of George Foster. In her introduction to the 1831 edition of Frankenstein she does not mention Aldini, but "galvanism" was among the evening discussion topics before she experienced her "waking dream" that led to her writing. Chapter 5,

169-410: Was reluctant to intervene in the controversy with Volta, he trusted his nephew, Giovanni Aldini , to act as the main defender of the theory of animal electricity. Galvani actively investigated animal electricity until the end of his life. The Cisalpine Republic , a French client state founded in 1797 after the French occupation of Northern Italy, required every university professor to swear loyalty to
