Editor's Take:

Pascal packed a remarkable range of achievements into a short life of just 39 years. As a teenager he built one of the first mechanical calculators to help his father, a tax official, with his sums. He made important discoveries about air pressure and vacuums, and the scientific unit of pressure, the pascal, is named after him. With Pierre de Fermat, he laid the foundations of probability theory, originally to answer questions about gambling. His later writings, collected as the Pensées, include 'Pascal's wager', a famous argument for believing in God.
