Gottfried Wilhelm (von) Leibniz (1646-1716) was a German mathematician and philosopher. He developed differential and integral calculus notation. His philosophy is noted for its optimism. Leibniz made major contributions to physics and technology, probability theory, biology, medicine, geology, psychology, linguistics, and computer science. He wrote works on philosophy, politics, law, ethics, theology, history, and philology. He wrote in several languages, but primarily in Latin, French, and German. He was a life member of the Royal Society and the Berlin Academy of Sciences, drew up its statutes, and served as its first President.
Leibniz defended his thesis in Philosophy at 19 but the University of Leipzig turned down his doctoral application and refused to grant him a Doctorate in Law.
