Léon Bollée’s calculating machine was the first true mechanical multiplying calculator, utilising an internal multiplication table ‘pre-programmed’ in brass to provide instant multiplications at a single turn of the handle.
Léon Bollée’s calculating machine was the first (after two comparatively forgotten machines by Barbour and Verea) to succeed as a true mechanical multiplying calculator, utilising an internal multiplication table ‘pre-programmed’ in brass to provide instant multiplications at a single turn of the handle.1
