Born in Germany in 1646, Gottfried Wilhelm von Leibniz was known as one of the greatest philosophers of his time. He was known as a religious, Christian man, who valued family. He was a scholar in mathematics, language, literature, metaphysics, and authored many books. Leibniz is also known for his development of the binary system, the mechanical calculator, and for his contribution to what was later to become the subject of topology. He is likely most famous for being involved in one of the

**great debates**of his century - the claim to developing calculus; it is believed that Leibniz and Newton simultaneously and independently developed methods in calculus. While Newton accused Leibniz of stealing his calculus methods, it is now thought that the two mathematicians had different approaches to calculus. Leibniz developed a geometric approach to calculus, using summation notation.Sources:
