Gian Domenico Romagnosi

From Wikipedia, the free encyclopedia

Gian Domenico Romagnosi (December 11, 1761 – June 8, 1835) was an Italian philosopher, economist and jurist.

Romagnosi is believed to be the first person to publish, in 1802, an account suggesting a relationship between electricity and magnetism, about two decades before Hans Christian Ørsted's 1820 discovery of the same relationship. Romagnosi's account of an electric current from a voltaic pile deflecting a magnetic needle, published in an Italian newspaper, was largely overlooked by the contemporary scientific community.
