Blaise Pascal
Blaise Pascal, oil painting by an anonymous artist, c. 1650; in the Musée Carnavalet–Histoire de Paris, Paris. Pascal laid the foundation for probability theory.
The Pascaline, designed by Blaise Pascal between 1642 and 1644, is considered an early digital calculator because it operated by counting discrete integers.1
Unlike analog devices that might measure continuous quantities, the Pascaline functioned by manipulating dials to perform addition and subtraction, effectively processing numerical values as distinct, countable units. This mechanical approach to integer-based calculation established it as a foundational precursor to modern digital computing technology.213
