This marvelous adding machine was designed and built between in 1692 and 1694 by the brilliant German mathematician and philosopher Gottfried Leibniz. Two original machines were built.
Leibniz was inspired by Pascal's design for an adding machine, known as the Pascaline, developed in 1642. Leibniz's mechanical innovation, called the stepped cylinder, later inspired the miniaturized form of the Curta Calculator, designed in Nazi-occupied Austria during WWII.
Liebniz's original is on display at the Niedersächsische Landesbibliothek (the National Library of Lower Saxony). A replica is on display at the Deutsches Museum in Munich.
