Freiherr von Gottfried Wilhelm Leibniz

Born in Leipzig in 1646 and dead in Hanover in 1716, Leibniz was a German polymath whose work reached across philosophy, mathematics, science, law, history, and public service. He studied law and philosophy while still very young, then built a career not only as a thinker but also as a diplomat and adviser attached to German courts.

He is especially famous in philosophy for works such as the Monadology and Discourse on Metaphysics, where he tried to explain reality as orderly, rational, and intelligible. In mathematics, he is widely credited as a co-developer of calculus alongside Isaac Newton, and the notation he introduced, including the integral sign and the use of d for differentials, became enormously influential.

What makes him especially interesting as an author is the range of his curiosity. His writing connects abstract questions about mind, matter, and God with practical interests in engineering, libraries, politics, language, and scientific method, giving his books an unusual mix of precision and imagination.
