Transcript of Luigi Galvani

Luigi Galvani Luigi Galvani and Alessandro Volta Alessandro Volta, a professor of physics in 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 conduction's were caused by a specific electricity intrinsic to animals. Volta believed that the contractions depended on the metals Galvani used to connect nerves and muscles in his experiments. By experiment Alessandro Volta found that it was the two dissimilar metals, not the frog’s leg that produced the electricity. The frog’s leg was just an indicator of presence of the electricity. After the controversy with Volta, Galvani kept a low profile partly because of his attitude towards the controversy, and partly because his health and spirits had declined, especially after the death of his wife, Lucia, in 1790. Early Life Luigi Galvani was born on September 9,1737 in Bologna, Italy. His family was not aristocracy, but they could afford to send at least one of their sons to undertake a scholarly career. At first he wished to enter the church and join a religious institution but was advised not to. Instead Galvani decided to take a medicine course at the University of Bologna. Along with medicine Galvani learned the theory and practice of surgery. He Graduated in 1759. Legacy after death Landmarks Luigi Galvani has 3 landarks in honor of him. Galvani’s monument,Liceo Ginnasio Luigi Galvani, and his home. Galvani's monument can be found at the Univestity of Bologna while his home has been perserved and can be seen in the middle of Bologna. Liceo Ginnasio Luigi Galvani is a famous secondary school built back in 1860. Early Life His Experiment While cutting a frog’s leg, Galvani's steel scalpel touched a brass hook that was holding the leg in
place the dead frogs leg twitched. Further experiments confirmed this effect, and Galvani was convinced that he was seeing the effects of what he called animal electricity, the life force within the muscles of the frog. Galvani's report of his investigations were mentioned specifically by Mary Shelley as part of the summer reading list leading up to an ad hoc ghost story contest on a rainy day in Switzerland — and the resultant novel Frankenstein — and its reanimated construct. However, there is no direct mention of electrical reanimation in Frankenstein. Galvani's name also survives in the Galvanic cell, Galvani potential, galvanic corrosion, the galvanometer and galvanization. The Società Chimica Italiana awards a medal to recognize the work of foreign electrochemists. The crater Galvani on the Moon is named after him.
