The person for whom Pascal is named, Blaise Pascal, lived from 1623 to 1662. He was a child prodigy and accomplished mathematician. In 1642, at 21 years of age, he invented a calculation machine. Pascal is credited with the discovery of the mathematical theory of probability. He also made fundamentally important contributions to number theory, geometry, and the advancement of scientific theory in the face of religious criticism.
