Eudiometer truly pioneered by Count Alessandro Volta (1745–1827), an Italian physicist who is well known for his contributions to the electric battery and electricity. Aside from its laboratory function, the eudiometer is also known for its part in the "Volta pistol". Volta invented this instrument in 1777 for the purpose of testing the "goodness" of air, analyzing the flammability of gases, or to demonstrate the chemical effects of electricity. Volta's Pistol had a long glass tube that was closed at the top, like a eudiometer. Two electrodes were fed through the tube and produced a spark gap inside the tube. Volta's
Alessandro Cruto the rest of his life between his family and his old laboratory. He continued his experiments on the accumulation of atmospheric energy and the invention of a toy called "mosca elettrica" ("electrical fly"). Cruto died, almost forgotten by all, in 1908. Alessandro Cruto Alessandro Cruto was an Italian inventor, born in the village of Piossasco, who created the incandescent light bulb. Son of a construction foreman, he attended the school of architecture at the University of Turin, while also attending Physics and Chemistry lectures with the dream of crystallizing carbon to obtain diamonds. In 1872 he opened a small workshop
