Carlo Matteucci was an Italian physicist and biologist, best known for his work in the field of bioelectricity. Born on June 21, 1811, and dying on December 8, 1868, he is recognized for his pioneering studies that explored the electrical phenomena associated with living organisms, particularly focusing on the electrical properties of muscle and nerve tissues.

Carlo Matteucci investigated electric currents associated with muscle using sensitive galvanometers. Museo Galileo preserves an instrument marked for his muscle-current work in 1840: an astatic galvanometer with suspended needles, many turns of fine wire and a readable scale. The apparatus connects a weak electrical signal with a mechanical deflection, illustrating why instrument sensitivity and suppression of the background geomagnetic field mattered for early physiological measurements.[ref]
