Gottfried Wilhelm Leibniz

What Leibniz contributed

Gottfried Wilhelm Leibniz published an account of binary arithmetic in 1703, linking positional calculation to combinations of zero and one. Binary numeration alone did not create digital computing. The modern synthesis required Boolean logic, switching theory, reliable two-state components, coding schemes and machines capable of storing and transforming long sequences. The topic begins with early modern devices associated with Wilhelm Schickard, Blaise Pascal and Gottfried Wilhelm Leibniz, but it should not be narrated as a parade of solitary inventors. These machines grew from long traditions of numerical notation, abaci, counting boards, clockmaking and precision metalwork. Pascal's calculator was designed around addition and subtraction for administrative arithmetic.

Why it mattered

Provides a robust common discrete representation for machine storage, processing and transmission. Reduces the mental and written burden of executing repetitive arithmetic procedures.
