Which inventor created the advanced mechanical calculator that preceded the Stepped Reckoner?
Answer
Blaise Pascal
The context for Leibniz's breakthrough required understanding the limitations of prior mechanical aids. The most advanced calculating machine existing before Leibniz focused his efforts in the 1670s was the Pascaline, developed in the 1640s by Blaise Pascal. While brilliant at handling addition and subtraction through intricate gear arrangements and carry mechanisms, the Pascaline lacked the direct multiplication capability that Leibniz sought to engineer into his machine, forcing users to rely on tedious, repeated addition.
