| name = Luigi Torchi | birth_date = {{Birth year|1812}} | birth_place = Italy | nationality = Italian | fields = }} Luigi Torchi invented the first direct multiplication machine in 1834.[1] This was also the second key-driven machine in the world, following that of James White (1822)[2]. 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. The machine was exhibited in Brera between 1834 and 1837; it was later found by Giovanni Schiaparelli in bad conditions. After that, are not known further information about the machine.
