Gottfried Wilhelm Leibniz (1646 - 1716) Was Born

Leibniz was a German philosopher and mathematician who wrote primarily in Latin and French.
He invented infinitesimal calculus independently of Newton, and his notation is the one in general use since then. He also invented the binary system, foundation of virtually all modern computer architectures.
He was, along with René Descartes and Baruch Spinoza, one of the three greatest 17th-century rationalists philosophers. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in biology, medicine, geology, probability theory, psychology, linguistics, and information science.
