Leopoldo Nobili (1784 - August 5, 1835) was an Italian physicist who invented a number of instruments critical to investigating thermodynamics and electrochemistry. After attending the Military Academy of Modena he became an artillery officer. In 1825 he developed the astatic galvanometer, a type of sensitive ammeter, an instrument for detecting electric current. He worked with Macedonio Melloni on the thermomultiplier, a combination of thermopile (electronic device that converts thermal energy into electrical energy) and galvanometer. He was appointed professor of physics at the Regal Museum of Physics and Natural History in Florence where he worked with Vincenzo Antinori on electromagnetic induction. Because of his researches, he is regarded as one of the Italian pioneers in the field of electromagnetism. He died in 1835 at the age of 50 or 51.
