Born 19 June 1623
Died 19 August 1662
Frenchman Pascal developed one of the world's first accurate mechanical calculators, the Pascaline, in the mid 1600s. This predecessor of the modern computer was presented in an elaborate handcrafted box. The Pascaline was not a commercial success in Pascal's lifetime however; it could do the work of six accountants and people worried that jobs would be lost.
