Bollée (Replica)
Direct multiplier with multiplication block
1889
In 1889, the Frenchman Léon Bollée from Le Mans won a gold medal at the Paris World Exhibition with a direct multiplier. In the machine, Bollée represented the small multiplication tables in form of round rods on a base plate. For each position of the setting mechanism - sliding in a movable carriage - is a multiplication block of this type represented. Only a limited series of this extremely heavy machine was built. However, the importance of Bollée's design became apparent only a few years later with Otto Steiger's series-produced "Millionaire" calculating machine, in which Bollée's solution for the multiplication block was used in a slightly modified form.
