Freiherr von Gottfried Wilhelm Leibniz

Born in Leipzig in 1646 and later active in Mainz and Hanover, Leibniz built an unusually wide-ranging career as a philosopher, mathematician, jurist, historian, diplomat, and political adviser. He earned a doctorate in law while still very young and spent much of his life working in public service as well as scholarship.

His ideas reached into many fields. In mathematics, he is famous for major work on calculus and for notation that remains in use. In philosophy, he wrote about metaphysics, reason, knowledge, and the nature of reality, always aiming for elegant systems that could bring many kinds of knowledge together.

Leibniz died in Hanover in 1716, but his reputation only grew after his lifetime. Today he stands as one of the great universal minds of early modern Europe, admired not just for individual discoveries but for the sheer range and ambition of his thought.
