Giovanni Aldini (April 10, 1762 – January 17, 1834), an Italian physicist, became professor of physics at Bologna in 1798. His work was chiefly concerned with galvanism 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 engaged in public demonstrations of galvanism, such as on the executed criminal George Forster at Newgate in London.
