Gottfried Wilhelm von Leibniz
b. July 1, 1646, Leipzig
d. November 14, 1716, Hannover, Hanover

German philosopher, mathematician, and political adviser, important both as a metaphysician and as a logician and distinguished also for his independent invention of the differential and integral calculus. 1661, he entered the University of Leipzig as a law student; there he came into contact with the thought of men who had revolutionized science and philosophy--men such as Galileo, Francis Bacon, Thomas Hobbes, and René Descartes. In 1666 he wrote De Arte Combinatoria ("On the Art of Combination"), in which he formulated a model that is the theoretical ancestor of some modern computers.
