Giuseppe Domenico Botto (4 April 1791 – 20 March 1865) was an Italian physicist.
[1] In 1830 Botto described in a note a prototype electric motor on which he was working and published a description of it in a Memoria titled "Machine Loco-motive mise en mouvement par l'électro-magnétisme" to the Academy of Turin around 1836.
A device built on the basis of his description was part of the collection of scientific instruments of the Grand Duke of Tuscany, which is now kept at the Institute and Museum of History of Science in Florence.
Botto experimented with electrolysis of water using a manual generator of electric sparks, the electric magnet designed by Leopoldo Nobili and Vincenzo Antinori on the basis of the discovery of' electromagnetic induction made by Michael Faraday in 1831.
In 1833 he tested an iron-platinum thermocouple wrapped as a chain around a wooden stick which generated a current when heat from a flame was applied,.
