Luigi Torchi invented the first direct multiplication machine in 1834. This was also the second key-driven machine in the world, following that of James White (1822). Very little is known about the inventor and the machine. We only know that he was a carpenter; his machine was awarded of a gold metal from the Imperial-regio istituto lombardo di scienze, lettere e arti in Milan in 1834. A document of such occasion provides the known details of the machine, where a second document shows a drawing of the machine itself. However, no detailed documents about how it worked are known to exist.
