Where did the name Lightning Calculator come from?

The original quincunx was invented by Galton in 1873. When the original Model WD-4 Quincunx was first invented for industrial use electronic calculators had not been invented yet. There were however large mechanical calculators being used in industry at the time called "Lightning Calculators".

Well you guessed it, it was named after this calculator because it could quickly demonstrate concepts. We occasionally get questions from antique dealers who find these devices to ask if there is any connection with our company. The only connection is that the original inventor copied the name. Since the name has been associated with quincunx boards over the years we still call ourselves "Lightning Calculator".
