Well-known pioneers of electrical engineering include Alessandro Volta with his battery (voltaic column) developed around 1800, Humphry Davy as the inventor of the arc lamp presented in 1809 and Moritz Hermann von Jacobi, who built the first rotating electric motor in 1834. In the middle of the 19th century, the development of electrical engineering gathered momentum. During the German Wars of Unification (German-Danish War 1864, Prussian-Austrian War 1866, Franco-Prussian War 1870/71), the military looked particularly favorably on the rapid further development of proven, usable telegraph technology. << Back
